Since the automobile was created, there have been many inventors looking to improve their cars with their own work. The car-audio systems are just the same in that hobbyists have constructed a dizzying array of systems from car audio component speakers to systems requiring vans to carry.

Installing a car stereo car audio system starts with the car stereo. Car stereos come with different features such as CD changers, fancy displays... or just a radio. Systems having a high power output rating have a limited frequency range and are designed to be loud. For getting clearer and crisper sound one should purchase higher fidelity systems, which offer a wider frequency range with a smoother response. Persons who like to hear classical music would be interested in systems of high fidelity rather than volume. However, classic rock 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!

Lay out of the car needs to be examined after outlining the specifications of the system that one wants. If one doesn't want do do some big modifications then one needs to order speakers of the proper dimensions suitable to the audio car component which are available in many standad sizes - six inch diameter for example. Amplifiers can be placed at a convenient place anywhere so that it can be connected with wires to all the speakers as well as the stereo.

You will basically be ready to install your system once you have worked through all of this. One point consistently remains the same across the board (though it can vary greatly between cars): always make sure that the ignition is turned off and the battery disconnected when you start work on it. These are important practical and safety precautions. Both the car and stereo will have come with manuals outlining installation instructions, and beyond that it's up to you. One final piece of advice: do not run amplifier wires inside the car cab; it tends to make people nervous!
