Adding an Amplifier
Last Updated: October 25, 2006

Installing aftermarket speakers is a major improvement in the audio department of your Beretta. But sometimes your head unit just doesn't have the wattage output to power your new speakers at the recommended RMS level. This is where an amp comes into play.

Tools Needed
· Trusty Phillps-Head screwdriver
· Wire strippers

An amplifier receives the sound signals from your head unit via RCA lines. The back of your aftermarket head unit will have atleast one set of RCA output jacks, they should be red and white. If you buy a wiring kit from somewhere this will have the RCA lines with it. Plug the lines into the back of your head unit and plug the other end into the corresponding colored jacks on your amp.

Next thing you'll need to be wiring up is your remote wire, this sends the signal from your head unit to your amp. It effectively is a remote turn on for your amp so that the amp doesn't stay on all the time and kill your battery. Coming out of the back of the head unit is your remote wire, it is usually blue/and will be labeled remote. From this wire you can run almost any wire that carries a signal and hook it to the terminal on your amp where it says remote. Simple enough, eh?

Next step in wiring your amp is the ground wire. This wire should be of a larger gauge than the previous ones, and will normally be black or brown. This should connect to a screw somewhere that goes directly into metal. After you have it screwed into metal you can hook it up to the large terminal on your amp marked Ground or ( - ).

Next up is the power wire. This one will need to be connected your battery, or a strong electrical power source. You will have to go through the firewall with this one, and that usually requires making a small hole. The power wire will usually have a fuse in it to prevent a power surge from frying your amp. Once you get it fastened to the battery or other power source you can hook it up to the large terminal on your amp marked either Positive, Power, or ( + ).

Lastly you will need to hook this up to your speakers, depending upon how many channels your amp has this can be confusing. Basically you will just need to take the ( + ) and ( - ) wires from your speakers and connect them to the corresponding terminals on your amp. Do not connect there to the power and ground terminals, your amp will have an area on a different side from these terminals specifically for the speakers.

This pretty much wraps it up, however there are some things that are specific per amp, this is just a basic wiring description and you should consult your owners manual before attempting this yourself. accepts no responsibility for any accidents with wiring, or malfunctions.
