Installing an Amplifier

Deciding on an Amp

Let's have a look at installing an amplifier or what most of us simply call an Amp. If you are planning on operating a sub or two with mid-range and tweeters then you'll need a couple amps. There are a number of different types, some use one to power subs alone,some use multiple amps to power their systems. Some amps have built in crossovers that can cross over different frequencies that are dedicated to a certain speaker. some amps are dedicated to a full range signal,such as a set up for 3 way speakers. Big subwoofers sound the best playing in 100 Hz and lower. How much power your amp needs depends on how many speakers you plan on driving with it,it should be able to put out 1.5 to 2 times the power continuously as the lowest power speaker that is hooked up to it. You want amp that has enough power for your speakers so :clipping does not become an issue. This is where the sound wave squares off and the top and bottom of the sound wave gets clipped off. The whole idea is to get maximum performance and years of enjoyment from your system. For now lets just look at the basic set up.

If you want thump,the only way to get it is with a quality amplifier. Tip #1,don't cover your amp,it needs cooling! And make sure the amp is mounted solid.

Usually mounting your amp under the front seat works the best for cooling as there is plenty of air circulating under there. This is where most amp manufacturer's recommend mounting. It also gives you an opportunity to do a thorough cleaning job underneath.

A little planning will save a lot of grief when you're running your power supply for your amp. Securely mount where ever you need to. This will insure trouble free operation of your amp because you'll know your power is properly tended to.

When ever possible use an existing hole in the firewall to run your amps power though into the passenger compartment. This saves time knowing that there is clearance behind this part of the firewall.

Every modern stereo head unit has what's called a remote signal control wire. This is the wire that tells your amp to turn on. Originally this wire was designated as a power antenna wire and can be used for either application even in this day and age.

Be sure to use a suitable ground for your amp. Using either a wire brush or a small piece of sand paper so that you have true metal to metal contact. after the ground is secure,hit it with a quick blast of spray paint to seal it and prevent any type of rust from forming. Rust makes a lousy ground.








Make sure you read the instructions very carefully when it comes to the wiring. Many,many problems have come from seemingly slight mistakes. Knowing what the instructions say can prevent hard earned money from going down the tubes..yes,speaking from experience. Be sure to note what color RCA is coming from what channel from the head unit. double check all connections before powering up any amp.

Now that your installation is complete,follow the manufacturer's instructions and adjust settings for the best sound.
