A car stereo amplifier is a necessity if you take your car audio seriously. A car stereo amplifier is what helps determine the type of audio output your stereo will produce. If you have never experienced what a car amplifier can do, you will be blown away at the quality of sound that can be achieved. In fact, once you hear your favorite music played with the power of an amp, you will be instantly hooked.

When you decide to purchase a car amplifier, one of your first decisions will be where to place it in your vehicle. You have several options but keep in mind an area where the amplifier will have the best air circulation. Common areas to install the amplifier include the trunk or under a seat. Also remember that the amplifier needs to be grounded so a metal surface to attach it to is key.

Most people will have professionals install their car amps. If you are a do-it-yourselfer, the next step is deciding how to connect the amplifier to your car stereo. RCA cables are the common cable type to use and they are used to connect the low level radio output to the low level input of the amp. There are other cable set-ups to use and some precautions to take before hooking up cables. These precautions should be laid out fairly well in the user's manual.

There are a few things to keep in mind when installing a car amplifier:

1. The amplifier should be installed on top of metal as a ground conductor. 2. Ground cables should be connected before the RCA cables. 3. Avoid installing power cables next to RCA cables to help avoid extra noise.

Again, the user manual should go over these elements in depth. Number one is very important, since newer model cars are made mainly of fiberglass, it may be difficult finding a solid piece of metal to attach the amplifier to.

When it comes to such technical issues as installing a car amplifier, you may be better off spending the extra money having one professionally installed. You can save yourself a lot of time and frustration. However, if you are adamant about doing it yourself, research online as well as reading the user's manual thoroughly to be safe and avoid any damage.
