To build audio-video system in the car isn’t easy. Space in the car is limit and chairs which cause spread of voice hindered makes special problems.   And other trouble as like emerge from voice of machine car and also wind whir, especially when car was driven too fast. All of that can become obstacle / trouble factor.

For cars which have good voice absorption or good enough acoustic, it problem become easier. But for car which have less good voice absorption or bad acoustic, are needed special solving problem. Start from barricading voices which isn’t needed until solve barrier as like limitation space or chairs which hinder spread of voice.

Is needed by special technique and handling to solve that. That causes attend of an experienced installer is needed, because to build sound system in the car doesn’t just connect its component (best quality of speaker, head unit, best car DVD player and high quality screen monitor). Right position of tweeter for high voice, speaker for middle voice, bass and sub woofer for perfect bass voice in the good position very determine to build perfect sound system in the car. Of course the placed of screen monitor also determine the perfect audio-video system in the car.

An experiences installer will be able to set in order to sub woofer voice which is put in the backside car until intact to frontage.  In the same case also for speaker which is placed in the door, tweeter which is placed above dashboard near by front glass. Voice of tweeter has to be able to be heard perfectly in the backside of car.

High quality of component like car DVD player, LCD screen monitor, special car DVD player, DSP (Digital signal Processing), I-TA (Intelligent Time Alignment), DSO-3D (Dynamic Soundstage Organizer 3 Dimension), BEE-MP will make picture and sound of tweeter, speaker and sub woofer can see and heard perfectly wherever we sit in the car.

Driver who sits on the right side of course nearer to position and speaker which is right than  tweeter position and speaker which is left. So that for passenger who sits on the left side. In order to voice of tweeter and speaker which are on the right and left can be received at the same time both for driver and left side passenger so tools of DSP which have function to decompose voice and I-TA which has function to delay absorption voice time which will set it.

And, its results are voice of music in the car will be heard in the ear perfectly. Oscillation voice metal which is produced by percussion, put in box melody string guitar, attendant and bass also knock of piano key heard very good and realistic.

As like music space, to build home theatre in the car also has problem. Effect of three dimension voice is so important for home theatre needs sweet spot where all of voices from various type of speaker arrive at the spot together and heard equal hard. Sweet spot is needed in order to mood of car passenger are in the film atmosphere which is being watched if wanted, parents can enjoy their journey while listening their favorite songs. Whereas their children play game as like playstation 2. thereby the traffic jam will not felt as unbearable trouble.
