Look at the sound engineer how to Diagnostics OBD2 teach you refit vehicle sound

Not long ago, in Beijing car city auto parts Diagnostics OBD2  focusing on "auto aftermarket service quality competition", many consumers car audio modification of put forward many questions. For this, the reporter visited the city auto parts, car audio senior technicians, please they sound refitted some problems do solutions for consumer reference.

Sheet metal is the first interference factors
What kind of car suitable to install what kind of sound, how to achieve the best effect. Generally speaking, the car in the course of driving when plate gold and sound low-frequency replay, if sheet metal partial thin words, can produce resonance a low frequency noise, will have more cover music of the low frequency part, thus affecting the car DVD stereoscopic effect.

Horn position is very Diagnostics OBD2  critical
In addition to the difference of structure of the body, but a different car the car original horn installation Settings habits are also different. If only buy installation common stereo system, the owners were the best car will be placed in the back door of the horn in the car door. And if installation AV system of words, as the pursuit of surround effect can be imitated, system and series car, but in the pillow parts the horn. As for the front door of the car horn, it should be the alto horn installed in front door plank place, Alt installed in instrument desk or A column in the best sound.

Engine noise can also affect effect
In addition to body thickness, the original car horn sound effect for the car the impact of outside, automobile engine working state and work noise characteristics in the car audio effect also have greater interference. Therefore, in the inside vehicle acoustics, must pay attention to in the engine parts the soundproof cotton, with a view to play a sound Diagnostics OBD2  insulation, sound absorption, purify crew enjoy car audio environment.

Electronic system interference can not be ignored

In addition, with modern car height automation, car body of all kinds of circuit system is densely covered, the electronic system in owners bring great rides convenience and fun at the same time, but also to a certain extent interference people enjoy pure car stereo. General Japanese car circuit to acoustic interference will be a little bit small. This is because the Japanese car computer system often use less well than the system and the system more cars's sake, and the system beauty Outil de crochetage automobile cars use commonly vehicle-mounted computer frequency is higher, therefore more prone to interference sound system of electronic noise.
