one of those wires is the remote wire....that has to be connected to the back of the headunit...i honestly dont rememebr which wire youll have to strip and connect the remote wire to...its been a while...but thatll stop the amp from coming on, cuz the remote wire triggers it as an on/off switch when the headunit (car) turns on, the amp will switch on too...but not without that connection! so basically you need to find someone who's done an installation recently...this isnt the best forum for that...look around online...ask for some help in some kind of stereo forum..
sorry
