If you use the factory Mach amps, you'll also have a +12 volt source for the rem as well.
On the passenger side factory Mach amp, disconnect the 3 wire socket (directed away from cabin)
Using the tap and runs(or you can splice them), run speaker wire from the three wires to the amp.
The grey one is the rem wire, the blue/red one is the speaker level positive signal, and the green/black is the negative signal.
Using an RCA cable, strip the rubber off and separate the bare wires from the wire in the center. Twist the bare wires together and connect the wire from the green/black to it. Strip the center wire, then twist and connect it to the wire from the red/blue. Then connect the RCA to the amp
