Maybe large audio problem, maybe a blown amp? Options

[nightryder]

ok heres the deal, got a new stereo deck, wired it in, everything it great. The only weird thing was a strange static in the right front woofer. Next day I go to use it and its not working, so i take it all apart, rewire it and its still not working. so i brought it back to best buy and they tested the deck, told me it was fine but it sounds like it could be a shot wire in the harness.

So then my idea was to test the power wire, see whats up, and re run a power wire from my ignition and that would be that. So i run the wire and i get power, but no sound. So i check the rest of the wires and they are all screwed, some arent giving me any power, some ae giving me negatives and whatnot. I check continuity in the harness, and thats fine, the next piece is the amp.

Anyone have any info on these amps and how i can test it, and/or replace it?
