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.

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.
Below we will introduce some amplifiers selection of some tips.

To solve the resonance noise the best opcom op com car audio tuning method
Bass on the body
opcom op com except for the ear, also can let the body and produce a kind of resonance. No matter is the head, bones or skin, or even oral. Teeth. Each part of body will be due to low frequency and produce a kind of resonance. This resonance makes people feel very comfortable, this resonance to release the pressure ...
Do not remember how many times have talked about a topic, but still have quite partial person in common with my contact or to ask the " word " actually has the congenital golden ears is certainly feel just like a fish in water, but mainly to long-term practice listening, today according to Beijing digital industry requirements again, over five years ago in the magazine talked about " old ", a person for more than ten years experience summarized as follows for your reference ..1. ( but with an equalizer, the equalizer to about 75% of the volume of the volume .)
2 setting amp installation completed first will host . Amplifier volume are kept small to " 0 ". The amplifier frequency point and other functions:
A. sound field amplifier crossover switch set in high ( HIGH PASS or HP ):
Crossover switch between 80HZ-120HZ opcom op com ( usually first mention 90HZ as reference )
B. sound field amplifier is set in high ( HIGH PASS or HP ): ( if no sound field configuration is omitted )
Crossover switch is set at 200HZ - 400HZ
C. subwoofer amplifier frequency divider switches are set in the low pass ( LOWPASS or LP )
Crossover switch in 80HZ - 120HZ ( super bass amplifier as the front amplifier, crossover to a combination of consistent, if the offensive power is more than 90HZ, subwoofer amplifier must be less than 90HZ. Cannot have a 90HZ following 120HZ above, debugging, or back to the omission of certain audio voice, causing poor audio link )
D. All amplifier bass frequency enhancer ( EQ BASS ) return to zero or close ( OFF )
3 complete the above a predetermined action, into a vocal consisting mainly of disc to play, then the host volume from opcom op com zero to 80% - 90% ( e.g. ALPINE total volume for 35, 90% for 31, other brand is so calculated, over and above the sound volume, the host will probably output distortion signal to the amplifier input signal, causing excessive damage the horn or subwoofer monomer! )
4 now, don't back or front super bass loudspeaker has no sound!
(for some equipment collocation will produce bigger smaller gain effect, so it can be in any one of the power amplifier installation, even if the volume is zero but the host volume to 80% - 90% things will produce ranging from the size of the volume )
First put forward the volume switch power amplifier is increased gradually, until the front horn sound distortion sound so far, then the amplifier volume knob back view about half a clock dial ( such as the hour hand of the clock dial ), more action is to let up debugging main speakers sound field, in the main machine of the largest volume of output signal, also let power amplifier in the absence of distortion to produce lexia 3 diagnostic tool the largest output power, also let the front horn without distortion condition produced the greatest volume without cracking voice, rendering, and even burn the voice coil and malfunctions!
The volume of sound field debugging set properly, will host transferred back to normal listening volume, proceed to the next step and subwoofer convergence adjustment.
Super bass amplifier volume switch are increased gradually, until with the sound field sound the appropriate combination of make super bass playing in the instrument panel or dashboard of Frontier! If not always make super bass playing on the front panel, try super bass loudspeaker line inversion ( positive and negative line upside down ), perhaps can be improved when. When ultra low volume is too small can not reach the instrument board, too large to advancement in the trunk ring!
Finally, if there is a sound amplifier set, the sound field amplifier volume increase to recoil passengers can clearly hear, while seated passengers hear back sound so far, in order not to sound too big to influence of backcourt attack sound quality and sound field effect ( remember! In a formal tournament before sitting judge if heard sound field sound will be the soundstage depth project points)

Large dynamic DJ enthusiasts new darling: United States the MTX RT8PT MB Star C3 active subwoofer
According to incomplete statistics, MB Star C3 in the modified car stereo upgrade the original car's bass system number is up. Because the original car audio system is influenced by the power of the original car amplifier, bass effect is relatively poor, and can not express a whole atmosphere of the music, that require dynamic, or DJ enthusiasts, the original car stereo subwoofer system the upgrade is imperative for owners who started his car stereo, but due to not understanding, so the sound quality, although there will be requirements, but not too high. So many owners very happy just entered a modification of the road, you will start to increase the subwoofer.
Subwoofer be divided into the gun two kinds of active subwoofer and passive bass active subwoofer its own built-in amplifier subwoofer owners use when you do not need additional power amplifier; compared to the passive subwoofer shape and power of the active subwoofer choice can be more MB Star C3 flexible, the effect naturally more ideal. To tell you about today is the American audiophile-grade car audio, MTX RT8PT active bass gun, first take a look at how it looks:
Large dynamic DJ enthusiasts new darling: United States the MTX RT8PT active subwoofer
It is composed by an 8-inch subwoofer, a tunnel-style cabinet. The appearance of the box by a gray blanket wrapped carpet-wrapped box can be sustained from damage, and gray and all within the original car color matched, the back of the stereo to install a small amplifier, and a high-output guide tube.
Efficiency of the design of this high-quality, high-performance, high-output, very popular among consumers, it is compact and bass MB Star C3 explosive strong enough, can achieve the effect of a ten-inch bass speaker and amplifier and cabinet match and dive deep sound reproduction and high, turns out to be small and extraordinary. The small size also means that more easily placed, occupy less space. The most convenient is it to replace the original car audio enthusiasts host two input methods for high and low to bring the Gospel. Amplifier remote bass line with consumers while driving can while adjusting the size of the subwoofer, humane design is sufficient to prove the the MTX product to people- lexia 3 pp2000 centered design philosophy.
