Hey this is for the people who want to hook up and amp to a stock deck. Hook up the power ground and all that as usual. For the RCA look on your deck if you have this harness with 2 + and 2- hook that up first pair of + - to one speker and another pair to another stock speaker. As for the remote wire find your fuse box and just hook that wire up to one of the fuses. If your amp doesnt have the high low harnes hook up to to a stereo shop ask for the high low RCA hook up plug that into the stock speakers of your car then plug the RCA's into that. And you got power. If you have any questions just post here.
