Car audio amplifiers, to a large extent, determine the final audio output of your car audio. Selecting a location for the amplifier is therefore of great importance. Select a location that has good air circulation. It could be in the trunk or under a seat. It is always recommended that you use cables with larger diameters like RCA cables to connect the low level output of the radio to the low level input of the amplifier. Just in case your radio does not have a low level output, you will have to use a high-level speaker output. This arrangement is not preferred by most because of the noticeable increase in sound distortion. This arrangement works best when your amplifier is meant for bass only.

Another thing to take care of is the connection between the power antenna lead from the back of the radio to the amplifier. One can go through the user manual to find out the recommended gauge size for getting the right power and ground cables. It is always recommended that you connect the ground power cables before the RCA cables, to avoid damage.

A good fuse should be a priority for the system. Check the owner's manual for the proper rating of the fuse. Another important thing to note while installing amplifiers is that to ensure that the power cables do not run next to the RCA signal cables. If the cables are too close, it may lead to unwanted noise. If you have noise you are not able to stop, try using a noise filter. It can cut down the noise to negligible levels. The gauge cables for the amplifier ground or negative and the amplifier battery or positive should be the same.

Try to place your amplifier on some solid piece of metal, either in the body or the frame of your car. This is an important process, because most of modern day cars are built with fiberglass and finding a good ground conductor is always that much more difficult.

Although car audio installations are best done by professionals, real electronic geeks find great pleasure in installing the audio setting by themselves. There are literally hundreds of "do it yourself" help available on the Internet. You also have a great number of printed material on the subject. By following the steps, one can install a custom car audio system with relative ease.

Custom car audio installation is perhaps the most exciting aspect of having a good car audio. The first thing you need to do is to do a thorough analysis of your requirements. Planning is of utmost importance. Then you start with the installation of the amplifiers first. Installing car audio amplifiers is one of trickiest things that you can encounter. To begin with, acclimatize yourself with the wiring diagram. Choose a place which is a non-conductive surface and try and place your amplifier there, all the while being guided by steps provided by either through online resources or through user manuals. One good thing about installing car audio amplifiers is that you can always have a professional do the installation, should you find it cumbersome.

You can then go through the entire process step by step, like installing the car audio capacitors, placing the speakers at proper locations, and then connecting the various components involved in a car audio system. By following the guidelines given in various car audio guides, you can carefully connect the different parts with appropriate wiring. Once done you can check for the audio output. If it does not sound good, then you can try rectifying the same yourself or better still seek professional help. One can become pretty good at car audio installation with "trial and error" method. Constant practice would enable you to install your custom car audio, with relative ease. Check out online car audio installation guides, which can equip you with the "what's what" on car audio.
