You wire those wires into your rear speaker wires and they convert it to RCAs for your amp. The white ones are for one side and the gray ones are for the other. The black one is a ground, which usually isn't required for this. You'll also have to run a remote turn on wire. The easiest place to do this is to splice it into the hot wire in the back of your cigarette lighter.
