Well, I finally got this stereo thing figured out. Bypassed the factory amp and everything is good. The only problem I have now is that the positive battery post sparks when I put the cable on. It does not do this when I disconnect the radio. I followed the install directions, soldered, and used heat shrinks to make sure it stays in good condition. I don't see what the problem could be with the radio wiring harness, maybe someone can help me out? Thanks.
