How do you install an amp to 95 riviera?

Answer 1

Run your power, ground, and remote wires. Then connect your RCAs to the back of your CD player and your amp, then connect your speakers to the amp..-Shocker

I don't think the factory stereo has rca plugs in the back. You can run wires off the rear speaker wires of the stereo and wire those to rca plugs which you hook to the amp. Then you will have the rears running to the amp (for sub install). If you planned on using a 4-channel amp for all of your speakers, you could run rca's from the front channel wires and from the rear channel wires. Since they're going to an amp it won't effect the ohm rating going to the stereo.

I had to do this in my Fiero when I had an older CD-player that didn't have RCA plugs. A new stereo with sub outs and front and rear outs created much better sound.
