Ok so lately my door speakers haven't been working in my car. They seem to work intermittently and lately but at all. So I went to the boneyard and grabbed two more Bose speakers and hooked them up and nothing.

So now I'm. Guessing it's the wiring and maybe the Bose amp itself and honestly I don't feel like tracing down these wires unless it's fairly easy. So is there a way I can hook the speakers directly to the head unit and just skip the amp?
