Default Install an amp--few question

--if i wanna install an amp, i basically take the red & white audio cables out of the new head unit and connect to the amp..right? then run the wires from the amp to the speakers?

Yes, you need to get some RCA cables and connect your head unit to the amp. You will also need to run a remote wire from the back of the head unit to the amp. This wire is usually blue and could also be labeled power antenna. This turns the amp on and off when you turn your key on and off. You will also need to run a power and ground wires. Power needs to come off your battery.

The amp output is for additional speakers you are adding. Your roll bar speakers are powered off your head unit until you unhook them.

Your better off running new wire. With the added power, they will carry more signal-less distortion.

Any more ?'s, pm me.

Good Luck.

Now the answers to these questions depend on one very important question.

Are you using a factory or aftermarket stereo?

If you're using the factory head unit you will need something called a "line level adapter". This is a device that converts the output signals from the amp into RCA connections which can be wired to an aftermarket amp.

If you're running an aftermarket amp you can typically use the RCA Pre-Amp outputs on the back of it to drive an amp.

The amp will only power the speakers that it's connected to. If you're running an aftermarket head unit you would still need to wire the front speakers to the aftermarket head units internal amp. If you're running this off a factory head unit, you would simply leave that wiring alone when you install the wiring harness and only tap into the rear speaker wires.

Make sense?
