Chevrolet Trax Officer Figure resolve Autocom
In recent years, small SUV the battlefield Autocom suddenly surging waged. Start
rumors that Ford will launch the first wing Bo% of this market segment
in the last year, when many of the manufacturers have woken up, followed
by the small SUV mushroomed flocked. It
did not take long for the flourishing of the small SUV market, ten
thousand contend, many manufacturers the surface zhengzheng Xiangrong,
secretly infighting, has not been in this market entrants is also
eyeing.
While GM, of course, will not miss the opportunity to join the war, General mature small car technology momentum and the ever-expanding market in China, launched a small SUV, of course beat GM Group. Universal breath launched Do Keangkela Chevrolet Trax Opel Mokka Britain Vauxhall sale of four small SUV, General give them different market positioning to distinguish between different audiences, and same Group with platform launched variety of different brands of the same models, practices and Volkswagen slight point like, I do not know whether to play the same market effect
Saw the Chevrolet Trax, we will soon be able to blurt out: this not is not Keangkela the this? At first I thought so too, but by NEXIQ 125032 comparison, Chevrolet Trax and Ang Kela both have a lot of difference between the appearance of the interior, despite being a product of the same platform, but the design has been positioning area separate.
On the the Chevrolet Trax former face design use familiar family of networks designed front the Founder appearance domineering, the wild the exquisite delicate seemed than do Keangkela many. The bumper under both scratch-resistant plate design, but smaller and larger sensory decorative role. Body lines obviously the Chevrolet Trax seem tough many prominent wheel arches and straight waistline more people feeling the full force, plus larger front air grille design which takes the shape of domineering interpreted more intense phase than under Keangkela seems delicate, one sentence summary: Chevrolet Trax appearance like huge muscles bodybuilding sportsman, do Keangkela like Sven delicate young white-collar workers.
Chevrolet Trax location of the rear-view mirror is not as directly linked to the general models in the A pillar, but placed in a small window below. Rear visibility is more intuitive, to this point, you have to experience it to know; GM Tech 2 This rear-view mirror, there is a magical place, is the so-called "aerodynamic optimization" can be regarded as an optimization initiatives noise. Wheels is matt six-spoke design, this polished practice preferences of Americans, the higher tone the better

The elegant gentleman evaluation of the new Mercedes-Benz Digimaster 3
Traction, with the trend, Mercedes-Benz Digimaster 3 also playing a family form of mask design, we can draw the conclusion from the new SLK, CLS, C63 AMG and SLS AMG, which we see in the body of the new SLK more progress of shadow. The elegant in slightly outrageous appearance, his back to the people's attention. In addition, is not difficult to see from our test results, Mercedes-Benz has not only elegant word shapers, driving pleasure is equally important!
Driving a Mercedes-Benz to run wild in the streets may be very vulgar things, especially sitting SLK 350 inside, it seems while listening Easy Listening, while a constant speed on the highway, and deliberately concealed pitched exhaust noise and reserve plenty of power is what you should do.
But on the actual driving his gentle driving, it can be said that a kind of torture. Like wasted youth, GM Tech 2 only under hard acceleration, taps and lines, as well as to experience the thrill of high-speed cornering, can only arouse you returning to the impulse. For me personally, the effort Benz SLK up and down, is evident.
7-speed G-TRONIC PLUS automated manual transmission is correspondingly very quickly and very happy to obey the command of the ankle, wire the rest of the action, directly from the exhaust pipe to a dull response, I always remind myself, this is not a AMG old style, it is indeed unlike Benz, driving pleasure wells up, in addition to the full-throttle start moment delay, the daily performance of the transmission is very smooth.

Winter noise reduction has a knack body sound insulation should be interpreted J2543 with caution
The owner liu recently very depressed,
J2543 into the winter, the car noise increased, oneself before the 4 s shops have for vehicle replacement winter oil, although activated when the noise is down slightly, but the driving there is still no obviously improved. To this, the expert said that the automobile noise mainly divided into engine noise, resonance noise, wind noise and tire noise, oil change can only reduce the engine noise, but for other noise is powerless, winter to car noise reduction, in fact is a system engineering.
Engine carbon to remove
As a car "heart", engine while providing abundant power, but it brings noise is also the most direct. Winter car engine noise slants big, is usually low temperature make the oil viscosity change is high, in the car boot lubrication effect caused by the bad. Moreover, the cold weather also makes engine need to run for a period of time to reach the best operating temperature, it also increases the engine J2543 noise. If the replacement winter oil, engine noise still obvious slants big, and the vehicle is a distance does not decrease, it will need to consider whether or not the engine carbon deposit problems.
Xian specific card motor sports club directors XuZhi said carbon deposit is generally fuel or into the combustion chamber of the lubricating oil from the incomplete combustion. In the city traffic, due to the crowded road conditions make it always in stop-and-go state, engine can't keep high speed operation, fuel incomplete combustion produces a residue in the long run it will form carbon deposit, it is difficult to avoid. General ran train high speed, let the engine keep high speed driving a period of time can play the role of carbon removal.
In addition to removing carbon from the "source" up noise reduction method, can also by blocking transfer to Ds 708 the noise reduction. For example for nacelle firewall do acoustic processing, with a layer of high temperature resistant, flame retardant composite materials to directly from the engine to reduce the noise of the transmission bridge. If his car engine cover no sound insulation cotton word, also can go to add a layer of sound insulation cotton, so also can rise to reduce the effect of noise.

Car audio modification on collocation vas 5054a and knowledge of choose and buy
Car audio and home audio system, vas 5054a is the need to pay attention to match, especially HI - FI levels of audio equipment, tie-in and appropriate, can give full play to the potential of the system, tie-in undeserved word, then can produce the "bottleneck", namely the best sound quality is not that part of the link to decide, but depends on the worst of link, this as the "barrel principle", water take how many, the shortest board decided. So, sound unlikely to meet their requirements, but also spent injustice, resulting in unnecessary waste. Therefore, prior about car audio collocation knowledge, for car audio modification if it is very necessary.
With the system, mainly consider the following two problems: the first is the link power matching, 2 it is of different brands equipment voice orientation.
Every link power matching in the process of collocation is one of the most important factors, which to a great extent determine the output quality is good or bad, but hold up vas 5054a is very simple, the guarantee enthusiasm to learn.
Power matching principle: car audio main component part is head, power amplifier and horn, head of the rated power can be equal to, or slightly less than the rated power amplifier, which not only can get good voice, also compare save cost, of course, if you don't consider the question of price, the nose is the power of the bigger the better, And amplifiers rated power to equal to or slightly greater than horn rated power, power amplifier power partial small, then push bad speakers, especially music element details and low frequency, if power amplifier power is too big a word of waste resources, namely, power consumption, reflected in the vehicle fuel consumption is, and the higher the price general power amplifier. Also, if you don't Mb Star C3 consider price questions, power amplifier is the bigger the better.
For most consumers, choose a good power amplifier than choose brand speakers or head to important, and that need to be in the investment of power amplifier money relative ratio horn or head to more, it is easy to get good voice.
Voice orientation principle: different brand has a different voice orientation, wild collocation are likely to reduce the whole system voice quality. In the sound field, mainly divided into three kinds of styles of voice: European sound, the sound, Japan sound. These three distinct voice features, the European sound to pay attention to the reduction of sound, exquisite flavor, real, rigorous is its most important manifestation of; The United States in the low frequency sound lay particular stress on the strengthening, pay attention to shock, western region the cowboy as straightforward and heroic; But Japan is like the sound of voice beautification and modification, though not authentic, but after the modification of the voice really close a lot of people taste. At present domestic brands of equipment to the United States more sound and Japan sound. Of course, there is the reader will ask, is there any "China sound", that's a very good question. With the domestic brand in the international no formed on the effect, because the domestic car audio toyota id4c key brand no one to be able to let consumer common recognition and understanding of the brand. However, with the rise of independent brands and domestic brands such as HuiWei, card lai, optimal's card and so on brand is gradually formed influence, the domestic market is brewing "China sound". Domestic brand sound out of style is varied, if collocation well also can form good voice, and the price is relatively more advantage.

Common loudspeakers sound Autocom way
At present most of the horn are still use
Autocom the traditional cone tub monomer movement before and after the voice, more academic parlance, the trumpet call electrodynamic (Electrokinetic Dynamic) or Moving Coil (Moving Coil). In the early 1877 years of German Siemens Erenst Vemer have moving-coil loudspeakers patent, but vacuum tube late to matters 0 seven years to formal use, but Edison the first player is stylus directly drive the diaphragm and then the horn amplification voice, so Siemens patent has not used. In 192 the United States singular company Chester Rice and Edward Kerrog and Edison bell company p. G.H okuto first to develop practical moving coil horn, for more than seventy years, in addition to material continuously improved outside, you take is the horn technology really have progress? Below are some common horn sound mode:
A, moving coil. Basic Autocom principle from Fleming left hand's law, a current word line and magnetic line of force vertical in the magnet north and south electrode, way line will be magnetic line of force and the current of the two interact with each other and mobile, in put a piece of diaphragm attachment in the word online, with the current change diaphragm has before and after the movement. At present more than ninety percent of the cone basin monomer are moving coil design.
Second, the electromagnetic. In a U type magnet in the middle of the erection removable cut plate (armature), when current flows through the coil armature are magnetization and magnet produces suction spending phenomenon, and at the same time, drive the diaphragm movement. This kind of design cost is low but the effect not beautiful, so multi-purpose in receiver and small on the headphones.
Three, inductive. And the electromagnetic principle close, but armature double, and magnet on the two voice coil is not symmetrical, when the signal current through the two armature to different flux will push each other and movement. And electromagnetic is different place is inductance can be regenerated lower frequency, but the efficiency is Cable for Renault Can Clip very low.
Four, electrostatic. The basic principle is urga (Coulomb) law, usually in the form of plastic qualitative diaphragm and aluminum inductive materials vacuum evaporation process, two diaphragm face to face put, when one piece with positive current high voltage when another slice of will induction out small current, by each other mutual attract repulsion action to promote air can make a sound. Electrostatic monomer because light quality and vibration dispersed small, so it was very easy to get clear transparent Alt, the bass power have not got caught, and its efficiency is not high, the use of dc original and easy to gather dust. At present such as Martin - Logan and manufacturers have successfully developed a static and moving coil hybrid horn, solve the electrostatic body bass the problem of insufficient, in the use of electrostatic earpiece is also widely.

Discuss car audio modification 20 elements obd2 center
Sound the first to: quality
Timbre is refers to the voice quality, obd2 center many people put it and "tone" confusion. What is called a voice quality? When you say a pair of shoes quality good. Do you refer to must be fit, comfortable, durable, and does not mean it made form not good-looking, Mao every now and then. Similarly, when you say a sound equipment quality good and bad, you also not in said it level how to, positioning as can be, but shows the equipment "be able to bear or endure not resistant to listen to!" As resistance to don't wear well, close as don't fit me. A sound quality very good equipment, its performance abroad is comfortable, resistant to listen to. You don't have to discuss it sounds comfortable, resistant to listen to reason, that is the experts, if you use your ears to judge will do. Some equipment can strong, amazing speed, analytic force is strong, but not durable listen to, that may be the problem of sound quality. A good stereo equipment, its quality obd2 center should be like a good voice, let a person the listen to not greasy.
Perhaps I said so you still think very abstract. Actually otherwise, I can again raise real column to illustrate. When you mention cloth, you will say, the material quality is very good. When you are eating steak, you will say: this cow row of meat quality is very good. When you praise a child, will say: the child's qualification is very good. So, when you hear a sound equipment or a musical instrument, you also will say: its sound quality is very beautiful. From the above these examples, you can clearly know "mass" is inherent nature. Quality high, very good, very beautiful represents the nature of this equipment is very good, it lets people sounds very comfortable. I can say quality audio equipment is the most important part of, so I put it in the first.
Sound the second to: tone
Tone refers to the color of the voice.obd2 center In English, the sound QUALITY (TONE QUALITY) and TIMBRE (TIMBRE or TONE COLOR) a look and then know its referred to is not the same thing. But in Chinese, the sound and tone are often mix, misuse. We often hear: the violin tone really cold, the violin tone really warm, said method, this means the violin in tone. Sound like light, is a color, but it is not your eyes see, but as a ears to hear. Usually, the warm tone voice is soft; The cold voice tone more hard. Too soft or too hard of course is not very good. Sometimes, tone can also use "noble", "beauty" of the word to describe, basically it is also one of the nature. But, like cloth is general, fabric refers to its material, fabric color but refers to the color of it, meanwhile there are still significant line. In the audio equipment review, tone as color general, it is to point to it unique color. Some equipment tone yellow, some partial white, some partial lexia 3 cold, and even you can say it is bring sorrow overseas blue. In short, audio equipment such as instrument general, almost from the more your tone is the fact. A $two million violin its tone may beauty has the golden luster; And a five thousand sets currency violin its tone may like faded pictures. Although each person view each different, however, "beauty" still has a recognized that "consensus", you can't say a upturned nose are "beautiful incarnation"; The same you can not say a cold blue tone of the equipment is beauty. This is our consensus to tone beauty.
Timbre is refers to the voice quality, obd2 center many people put it and "tone" confusion. What is called a voice quality? When you say a pair of shoes quality good. Do you refer to must be fit, comfortable, durable, and does not mean it made form not good-looking, Mao every now and then. Similarly, when you say a sound equipment quality good and bad, you also not in said it level how to, positioning as can be, but shows the equipment "be able to bear or endure not resistant to listen to!" As resistance to don't wear well, close as don't fit me. A sound quality very good equipment, its performance abroad is comfortable, resistant to listen to. You don't have to discuss it sounds comfortable, resistant to listen to reason, that is the experts, if you use your ears to judge will do. Some equipment can strong, amazing speed, analytic force is strong, but not durable listen to, that may be the problem of sound quality. A good stereo equipment, its quality obd2 center should be like a good voice, let a person the listen to not greasy.
Perhaps I said so you still think very abstract. Actually otherwise, I can again raise real column to illustrate. When you mention cloth, you will say, the material quality is very good. When you are eating steak, you will say: this cow row of meat quality is very good. When you praise a child, will say: the child's qualification is very good. So, when you hear a sound equipment or a musical instrument, you also will say: its sound quality is very beautiful. From the above these examples, you can clearly know "mass" is inherent nature. Quality high, very good, very beautiful represents the nature of this equipment is very good, it lets people sounds very comfortable. I can say quality audio equipment is the most important part of, so I put it in the first.
Sound the second to: tone
Tone refers to the color of the voice.obd2 center In English, the sound QUALITY (TONE QUALITY) and TIMBRE (TIMBRE or TONE COLOR) a look and then know its referred to is not the same thing. But in Chinese, the sound and tone are often mix, misuse. We often hear: the violin tone really cold, the violin tone really warm, said method, this means the violin in tone. Sound like light, is a color, but it is not your eyes see, but as a ears to hear. Usually, the warm tone voice is soft; The cold voice tone more hard. Too soft or too hard of course is not very good. Sometimes, tone can also use "noble", "beauty" of the word to describe, basically it is also one of the nature. But, like cloth is general, fabric refers to its material, fabric color but refers to the color of it, meanwhile there are still significant line. In the audio equipment review, tone as color general, it is to point to it unique color. Some equipment tone yellow, some partial white, some partial lexia 3 cold, and even you can say it is bring sorrow overseas blue. In short, audio equipment such as instrument general, almost from the more your tone is the fact. A $two million violin its tone may beauty has the golden luster; And a five thousand sets currency violin its tone may like faded pictures. Although each person view each different, however, "beauty" still has a recognized that "consensus", you can't say a upturned nose are "beautiful incarnation"; The same you can not say a cold blue tone of the equipment is beauty. This is our consensus to tone beauty.

To teach you to car lexia audio mixing techniques
A suit very beautiful car audio system,
lexia if it doesn't perform up to the sound of appearance, every effort results to zero, actually tuning of capability, must be accumulated a lot of experience, not short-term training can make, itself must be familiar with all sorts of equipment function and characteristics, accumulated enough professional technology after, get up to.
The purpose of the tuning is the value of the equipment will play out, finding more of god's voice, in fact this work, and is not very easy, because of its variables is too large, also because of this, tuning work is a quite fun and challenging things. In fact tuning work more than half is in the examination system, if the system wiring is not correct, or system collocation have questions, with no amount of time also can't adjust the due effect. So before you begin tuning before late must check a few projects:
1. Alt horn, or so channel, lexia and before and after channel, phase is correct?
2. Use single tone (MONO) signal testing, each a single voice, performance is consistent?
3. Measurement subwoofer to expand the power of the machine, and, in the volume, can have a lot of pressure drop (less than 12.5 volts)?
4. From expanding machine end measurement horn Yin resistance to correct?
5. Turn up the volume, listen to see horn have issued abnormal sound?
Mixing projects also has three key points:
1. The equilibrium degree: this means that each frequency band balanced degree, the proportion of each other, if the frequency response out-of-flatness of words, volume larger frequency band will advance to the distortion point, expanding machine and horn itself can't lexia balanced play, for no reason consumption meaningless current.
2. Sensitivity: the sensitivity of the whole system set is very important, once upon a time stage expander to electronic partials apparatus to expand machine, incorrect sensitivity setting signal is not input expanding machine before they have distortion, some host signal output is too small, expanding machine sensitivity, must turn up, cause signal-to-noise more bad, also appeared sound (Hiss sound), in this case is easy to produce engine noise interference, this is quite not correct system collocation.
3. Crossover point: crossover point set, in relation to the horn of the scope of work, the influence of the performance of the sound effect crossover point choice, there are many variables,toyota id4c key here is to decide the important voice performance levels, such as horn of the frequency response range, partials apparatus of the slope, vehicle itself resonance characteristics, expand the machine's power and the size of the horn, will affect the crossover point setting, fixed the crossover point and band type crossover point, it is difficult to get what you want equinox, trimming type is a more ideal way, there are many skills, not on the notes that, until the classroom detailing.
4. Front door plank horn of the actual performance: the front door horn performance, affects the overall effect, however, the most easily overlooked place, is here, because before the door, most is a irregular space, and is the metal plate niv plate of the resonant tank, shape belongs to the flat speakers, not ideal gold law, some door internal is a maze, some horn can only be fixed in the door inside, this is not the ideal resonant tank, some is the volume is too large, more than 50 liters, lock a 6 inch bass sound box, the result, 6 inches and a half horn bear power are lower, bass shape was gone, the front door internal processing is very important.
The purpose of the tuning is the value of the equipment will play out, finding more of god's voice, in fact this work, and is not very easy, because of its variables is too large, also because of this, tuning work is a quite fun and challenging things.

The car should make inspection and maintenance
When the door-to-door heating hot,
lexia 3 remind us the cold winter is coming. In before winter we also need to make the car inspection and maintenance.
Fox wiper blade into the preparation
Autumn rain more, wiper is used very frequently. And gum, guano and more inferior glass water often can make wiper blade damage. After winter weather turns cool will also speed up the soft wipers rubber aging, led directly to the glass front cleaning effect variation, influence ride safety. So before winter can check the working effect of wiper blade, when there is aging or beyond the reach of cleaning effect, can consider to change.
In addition, the weather turns cool, low temperature will appear rime, in this season, you want to pay special attention to front windshield of defrosting diffuser out wind is normal, quantity of heat is enough, if appear problem, to solve.
- brake system often check
Pay attention to brake fluid is enough quantity, when need should be timely add note or replacement. Always check the brake have become weak, lock, the brake pedal [strength if there is obd2 a change, when necessary, clean up the whole braking system pipe section.
Fox fangdongye pay attention to freezing point
Fangdongye for winter for transport is the most important, through summer and fall seasons, fangdongye consumption will usually large. If before and after water or find fangdongye change qualitative phenomenon, must carry on the replacement as soon as possible. We can also to 4 s store fangdongye freezing point and specific gravity of the inspection, to the north of the vehicle, the best should choose the freezing point minus 35 ℃ for the following antifreeze liquid products, must not less than 20 ℃ below zero, if a freezing point work play a fangdongye effect the.
- prevent battery "strike"
The weather turns cool, for the vehicle's battery also constitute a considerable threat. Parking flameout, don't forget to close the car light, because after a night of battery consumption, at any time may not electricity, can't start the car. In addition, try not to use in vehicle did not start CD, cigarette lighter on electrical equipments, traffic in the process also less with all kinds of vehicle electrical appliances.
Near the end of the general life of battery, car owners in the driving can have the feeling, such as car a few days he found dozen do not catch fire, fuel consumption increase, Lexia 3 v47 the car heavy, fuel consumption increase obviously, etc.
- belt wear need to change
Belt inspection is also not allow to neglect, if there was skid, fracture phenomenon, can make the related auxiliary loss function. The old belt wear and serious, make belt and pulley decrease the contact area. At this time as long as strong a pressure belt, belt is deeply sink into the groove of the pulley. The rubber belt and a aging problem, if belt rubber serious aging, must be timely change new belt.

Vehicle inspection items and erroneous zone
The car for you work some time, you renault can clip may have neglected to its daily maintenance. So if you prepare in 11 during driving long journey words, be sure to check his car is to maintenance date, if close to or has been cycle words or please go to the professional stores carry on the routine maintenance, and especially important inspection including oil, fangdongye and brake fluid so easy to make the vehicle has caused a serious security hidden danger when the damaged part.
Perhaps the first time owning a car friend may to maintenance period sciolistic, think that as long as in the maintenance of kilometers within the maintenance even normal maintenance. But manufacturer general meeting for next time maintenance work out a cycle, even if in the period of driving mileage does not meet the prescribed mileage is also the need for routine maintenance. For example, BMW automobile after-sale will be for each a non high-performance BMW car designated maintenance date, the official maintenance date for 1 year 10000 kilometers, that is to say whether to take the lead in 1 year period or in the road 10000 kilometers, are going to be the next phase of maintenance.
In addition, some DE system turbine car basic more or less exist certain oil loss, the trip before must according to check the oil reserves, conditional owners also accompanied 1 l ~ 2 l add oil, for the road of one thousand oil limit alarm in time to add. Whether the definition of general maintenance except through the mileage outside, cycle is reached then is also the need for maintenance, many owners will ignore cycle said. This chart shows that the vehicle is a BMW 1 series car, the traffic in the instrument desk computer clearly stipulates the next oil change mileage and latest time, of course, mileage and time is according to your daily driving habits and oil reserves and occur at any time of change.
In decided to drive a car on a long trip, the first step is to make sure is the trip road conditions and the BMW GT1 number of ride because, according to different road and the use of tire pressure is different. For the average normal original car is concerned, in before they leave the factory has been set a set of tire pressure standard, you can attach on vehicle from the manual and driving seat open the door to door place inquires the corresponding tire pressure, according to the number of roads in and choice of tire pressure, generally long distance high speed while driving tire pressure is unfavorable for the high value, to do moderate is the most safe.
Set the tire pressure and after the tyre for regular inspection, such as whether there is a slow leak and tied with nail phenomenon appear, such as signs that should be solved at once. Mr. ZouYun also suggests we, should also carry on vehicle related in fetal tools, such as use explosion-proof tire accident, in the low pressure state shall not exceed 30 km per hour speed to replace low tire service point, and in either case tire damage or be pierced by don't trying to draw foreign body.
Tire pressure set after mb star c3 the completion of Mr. Zou for we demonstrate the latest tyre test bench work principle. Different from general need to jack up the car, the device can be directly drawn on the vehicle suspension arm after the car is raised, so as to let the rear wheel impending is very convenient.

Let the original V-Checker V500 car audio on flying wings JiShuPian
Modern car in addition to pay attention to V-Checker V500 the control driving pleasure and ride comfort outside, also pay attention to the driver and take more other fun, such as video fun. More and more manufacturers are the car audio as one of the selling point, and constantly propaganda saying more than multichannel speaker system effect how good how to real reduction music essence flavor. From former scale with the radio to cassete machine to CD machine, has been developed to today's senior DVD multitrack 5.1 surround system, car audio system as an important driving pleasure factor has been exist and will always continue. But because the manufacturer is in automobile development cost considerations decided to the original car audio system always power is not big, sound frequency width reduction is insufficient, the original engine decoding generally and so on, these problems in various levels of the models in more or less exist. Many have a pair of "gold, silver and copper ears" of our car audio can be said and love and hate, love because like driving in enjoying the sound system brings listening pleasure, hate is because the original car audio system generated music always makes people feel there is always V-Checker V500 such and such defects, modification and to get into a fight damage the car decoration, car moving knife dynamic gun love dearly unceasingly. Therefore, the toad provide some tips through a small changes to don't want to get into a fight damage the car decoration and want to make the original car audio if increase.
Different levels of car, manufacturers provide car audio systems also have quality difference, so in this premise condition, we must look at how to improve her car segment the original sound system. We subdivided into three phenomenon: one is high enough fully bright and burr feeling heavy; 2 it is intermediate frequency is very thin, whether human or drums are seems to have no air no force; The third is low frequency divergent feel dizzy. Let's just for the moment according to these three phenomena to discuss.
First of all, in accordance with the said toad tips to debug the original car audio system before, please put the car balance all return to zero, which is usually within the host high school bass don't increase, because only by enhancing the frequency of a wave is out of the question, can only make the horn are more difficult to control V-Checker V500 the whole voice off-odor. Let the car audio system back to the original state to listen to, according to their ears to judge their own sound system in primitive state belongs to the above three phenomenon which judgment. After coming out, then look down toad tips:
A high enough, transparent and bright and burr feeling heavy (beginning ability requirement level: primary difficulty coefficient: 0 the highest difficulty standards for 10)
The problem generally appear in mini and small car this level, encounter this kind of situation, the high guard down, in the guard and a layer of about 3-5 mm thick low density sponge, high quality will improve immediately. The concrete with thick low density sponge depending on the Alt power and installation location, if from the ear relatively near with thick point, from the ear more far, with thin point, this kind of sponge everywhere all have, for example, computer graphics card box match to packaging graphics card sponge sheet. Such practice ability are not Digimaster 3 GG or MM, can hang around the high put one to two little fluffy cotton cloth doll accessories, through the put in different position high to listen to, take listening most comfortable position to put. Simple enough? But the effect than in guard put sponge a little time point.

Fine talk about acoustic noise Volvo VIDA DiCE method
A. Noise testing steps
System appear noise is to Volvo VIDA DiCE let each modified technician have a headache problem, however, have to master the noise search method, identification and remove skills can easily deal with these problems. Of course, noise have a great part of it is not standardized operation caused by, so to develop good habits can eliminate noise generation. For system noise can be three steps to deal with:
1. Identify
First deal with the noise of the system identification, listen carefully to noise type, pay attention to the following: what kind of symptom? Is what kind of noise? Noise is follow the whole system have? Noise is with volume size change and change? Noise from what when begin? Whether noise with the engine and speed and change? For how long?
2. Isolation
When you identify noise type, Volvo VIDA DiCE the second step is to analyze the failure circuit part, and will it isolation. Equipment problems were relatively easy to solve, so long as will equipment demolition and repair its function whether there will be a problem to change into a can, in here should pay special attention to, don't immediately will equipment change, because if there was short circuit or reverse equal status, you may burn another station equipment. So shall first will have the problem of equipment interface equipment and environmental check carefully, and then converter to test.
The isolation of the alternative is to skip or disconnect the equipment or circuit, and then check if there is the emergence of the noise.
3. Eliminate
To identify and analyze the noise, the next step is to eliminate noise, the noise can generally from three aspects Volvo VIDA DiCE to solve: the car environment, acoustics and electronic.
The car environmental noise mainly through the equipment put the position or connection ways, interior environment affect noise types have mainly clutter noise into, electromagnetic interference, and the other for the car environment caused by the noise.
Acoustic problems mainly is the phase, scattering, and the load disturbance shot problems. Electronic problems about filtering the main processing, power cord, ac signal, earth and other car electric to the influence of the audio system. Electronic processing requirements higher basic knowledge, and to oscilloscope, the signal generator, ford IDS VCM distortion tester etc instruments have higher understanding. Simple portable radio it is a to hum radiated interference problem dealt with better tools.

Teach you car audio modification lexia economic strategy
Audio is an important
lexia component part of the car. In the car audio wonderful music in the boxcars ring, not only is a kind of enjoyment, but also can make us relax. EMMA car audio network survey know: with the increasing number of private cars has, many people for car audio requirements is not satisfied with the original factory car audio configuration, car audio modification therefore become a beginning work.
ZhouZhiYong is a car DVD fancier, engaged in audio modification has more than ten years, he and sister together open car audio center in the same also have a good reputation. ZhouZhiYong infatuated with car audio, this from his car just sees one spot. He is now open the car the entire audio equipment added up to $130000! "A concert is a problem!" At the mention of her car, ZhouZhiYong will feel especially proud.
But, like ZhouZhiYong such car audio enthusiasts is minority after all, most people can't like him in lexia the car go to war. In fact in the ZhouZhiYong reception customer, low-standard cars modified occupy the most, "prestige car audio system was very good, modification is much necessary. And low-standard cars will be different, modified room is very big". Many people to refit acoustics, ask the first word is "whether you want to spend a lot of money". ZhouZhiYong said, when sound modification is not to spend big price, the key is the main clear his car pursuit is a kind of what kind of effect, and then you can according to the models and design work out a set of suitable for their own, ratio of the right sound configuration, "a lot of car 23000 yuan will only inside the carriage music atmosphere promoted a class".
Refitting the matters needing attention
The modified car audio shop a lot, but there is no lack of among them pass away the sham as the genuine generation. Therefore, if moved refitted idea, must pay attention to some items:
1, see refitting shop lexia have relevant departments issued certificate. In the modified acoustic process, installation is an important link, because want to change the car line, so even if you spend more money, if installation cannot guarantee, the car but is a kind of hurt, serious when even can cause potential safety problems. Therefore, must look for professional modified shop. Sometimes, from the installation time length can simple tell a modified shop have professional level. Professional refitting shop assumes a specific task, refitting process sleek, spend time is relatively short. Conversely, those who operate messy, when using a long shop will not be easily believe that.
2, horn as long as no logo will not want to buy.
3, don't blindly see refitted vehicle of the store. Many refitting the store is provided with modified good vehicle, but don't think his car can achieve the same effect, because those samples are mostly carefully build, unless you want to spend the same amount of money, it is hard to the shoulder to shoulder.
4, listen to ask. The average person is difficult to respectively on the market a wide variety of head and the performance lexia 3 diagnostic tool of the speaker. If have no idea, might as well listen to, but attention must listen to with a tune, because different head and the speaker to music performance ability is different, only listen to with a tune, can choose his favorite type. In addition, on the market the same kind of head and speaker sometimes have a large price difference, so, in determined before each modification to store much ask, consult price. But then pay particular attention to a bit, some modification shop intentionally given lower head price, but don't think so you just picked up cheap, in most cases, you must also at the same time they there refitting speaker, or you simply can't get low head, the reason is the somebody else's car audio and on the horn the head "loss" make up a deficiency back yet.
ZhouZhiYong is a car DVD fancier, engaged in audio modification has more than ten years, he and sister together open car audio center in the same also have a good reputation. ZhouZhiYong infatuated with car audio, this from his car just sees one spot. He is now open the car the entire audio equipment added up to $130000! "A concert is a problem!" At the mention of her car, ZhouZhiYong will feel especially proud.
But, like ZhouZhiYong such car audio enthusiasts is minority after all, most people can't like him in lexia the car go to war. In fact in the ZhouZhiYong reception customer, low-standard cars modified occupy the most, "prestige car audio system was very good, modification is much necessary. And low-standard cars will be different, modified room is very big". Many people to refit acoustics, ask the first word is "whether you want to spend a lot of money". ZhouZhiYong said, when sound modification is not to spend big price, the key is the main clear his car pursuit is a kind of what kind of effect, and then you can according to the models and design work out a set of suitable for their own, ratio of the right sound configuration, "a lot of car 23000 yuan will only inside the carriage music atmosphere promoted a class".
Refitting the matters needing attention
The modified car audio shop a lot, but there is no lack of among them pass away the sham as the genuine generation. Therefore, if moved refitted idea, must pay attention to some items:
1, see refitting shop lexia have relevant departments issued certificate. In the modified acoustic process, installation is an important link, because want to change the car line, so even if you spend more money, if installation cannot guarantee, the car but is a kind of hurt, serious when even can cause potential safety problems. Therefore, must look for professional modified shop. Sometimes, from the installation time length can simple tell a modified shop have professional level. Professional refitting shop assumes a specific task, refitting process sleek, spend time is relatively short. Conversely, those who operate messy, when using a long shop will not be easily believe that.
2, horn as long as no logo will not want to buy.
3, don't blindly see refitted vehicle of the store. Many refitting the store is provided with modified good vehicle, but don't think his car can achieve the same effect, because those samples are mostly carefully build, unless you want to spend the same amount of money, it is hard to the shoulder to shoulder.
4, listen to ask. The average person is difficult to respectively on the market a wide variety of head and the performance lexia 3 diagnostic tool of the speaker.

Choose amplifiers trick car audio modification bmw opps indispensable three common sense
Car audio as flow of the concert
bmw opps hall GuLv becomes a kind of enjoyment. Whether or not the car audio enthusiasts, in the face of these full of metallic simple sense equipment will be its unique magnetic deeply attracted. But perhaps for most people, how to choose and buy satisfaction of the audio equipment is a difficult problem.
Below we will introduce some amplifiers selection of some tips.
Determine the same benchmark amplifier power
Power is sound system is the most important parameter, said a sound system with load ability. This is also our when buy should be paid attention to in the first place. But if each manufacturer with different measurement datum to mark product performance, the lack bmw opps of enough know it is difficult to make objective comparison. Power amplifier is also so, in view of the power amplifier logo should pay attention to the following three points:
Firstly, the battery voltage.
Car battery voltage is often change, for the two kinds of common logo: 14.4 V / 100 w, 12 V / 100 w power amplifier are two different power description. Because of the car in the process of driving voltage basically in the 12 v or so, so in 12 v voltage condition the measured power value is more close to the truth. And with the constant voltage 12 v as the datum mark power amplifiers in reach more than 12 v can attain greater power.
Second, the harmonic distortion rate THD.
In comparison of the power amplifier continuous output power, should be in the same (or more close to) under THD value. Different THD value test out quality difference is very obvious, sometimes bmw opps the identification of the maximum power is very high, but is likely to its distortion and noise is also very high. So in check maximum power at the same time should also pay attention to the identification of THD value.
Thirdly, frequency range.
Power amplifier of continuous power output should be in its actual use frequency range for detection. For the power amplifier, should ask the identification complete detection range, only mark a frequency power value doesn't make any sense.
In determining the same reference, we can to compare the power amplifier. Usually, in the choose lexia 3 diagnostic tool and buy when sound system generally follow the principle of high power output. The greater the power amplifier output power, showing that they drive the speaker's ability is stronger also. The power amplifier should be greater than horn instructions power, if choose power partial small, in the long-term use of high power output, easy to burn out, still can bring about quality difference, distortion and the emergence of the fault.
