DAMMIT!! I just realized I got the stereo amp, not the mono.....You disregard those wires altogether, they aren't used.
Your aftermarket head unit should have a subwoofer outputs (RCA) where you run new RCA cables from your new head unit to the new amp. That factory wiring that goes to the factory amp isn't used at all anymore.
