But I utilize the RCA outs. There's also wires for the internal amp to connect to the factory speaker wires but they aren't used in my install and I have the option to turn off the internal amp for my deck.
ok so how do i know which wire is which? do i just match up the colors? And why didn't you use the internal amp wires? did you run your speakers through another amp? if so how do I go about doing that?
