if you are using an aftermarket wiring harness hook up the remote turn on wire on the new radio it should be blue with a white stripe to the harness also has a blue and white stripe and plug it in this wire turns on the factory amplifier if you are not using a harness you will have to locate the internal amplifier wire of the radio and connect that to the remote turn on on the aftermarket radio = answer = the inernal apm power wire is white on the black wire harness ANSWER if you dont want to use the factory amp. just run new speaker wires to each speaker.
