The cars have a long and coloured history when it comes to the modifications of "do-it-yourself" kind, and car-audio is not any different. The tilted amateurs built systems with variable complexity, of four audio component loudspeakers forf car of any type to the whole vans completion.

Lining up a car stereo car audio system begins with the car stereo. You can find stereos that feature CD changers, fancy displays... or just a radio! Some systems are designed simply to be loud, and feature a high power output rating, but have a limited frequency range. Higher fidelity systems offer a wider frequency range with a smoother response, making it sound clearer and crisper. Essentially, if you like to listen to classical - loudly or not - you probably want a system that focuses on fidelity rather than volume... but classic rock simply needs to be played loud.

Majority of the car stereos available today in the market come with four component speaker outputs, which tend to increase with the increase in price. The output is measured by parameters called impedance and power rating, measured in ohms and watts respectively. It is not necessary to go into the basics of these parameters to make a good choice. One has to simply take care that the impedance on the car audio component speakers that one selects matches with that of the stereo output channel exactly and that the wattage of the speaker should be either equal to or greater than that of the stereo. The speakers can be damaged if the ouput wattage of the stereo exceeds that of the speaker.

If you aren't satisfied with the sound coming from your car's stereo, and you want a louder, high-fidelity system, you'll need to get a separate amplifier. After you install the amplifier into your existing stereo, it will read the stereo's signal, amplify it, and then output this increased signal to your speakers. It's easy to add car audio component speakers with an amplifier - just be sure to use the output specifications of the amplifier and not the specifications of your stereo!

After you have outlined the specifications of the system you want, you must examine the layout of your car. Car audio component speakers come in many standard sizes - six inch diameter, for example - and unless you're looking to do some serious modifications, you obviously need to order speakers of the proper dimensions! Amplifiers can be placed anywhere convenient, but keep in mind you will have to run wires to all the speakers, as well as the stereo.

You will be ready to install your audio system in the car once you've worked all this out. The installation of the system varies greatly between cars. However one point common to all cars is that you should make sure that the car is off and the battery disconnected before you start working on it. Instructions for installation can be got from car and the stereo manuals and you are on your own for installing them. Finally, you should not run amplifier wires inside the car cab since it makes people nervous.
