I had the avic-d3 in and now i'm parting out my car and i put my stock unit back in and now my rears don't work. THe audio place ran new wires to my speakers and spliced the wire are is the door panels, i rewired those back and now i have no sound from the rear. The front works great. My sub is turning on but not my speakers. They didn't bypass the amp they told me they only sliced those wires and wired them into the back of the d3. Please help if anyone knows what the hell is wrong.

thanks.
