Ok I have a buddies deck here, he hooked it up, and it dont work. The deck is a pioneer deh-1500, it has the internal amp in it, everything powers up, but no sound, im thinkin the internal amp is gone, but i want to see if there is anything else that could be wrong.

Thanks.

most likly there is a speaker wire shorted to ground.

That's my second guess, the first was the amp was gone. Disconnect all the speaker wires and start to hook them up one pair at a time.

Ok I will get my buddy to try that out. Thanks.

if a speaker wire ever touched a live wire, that'll kill the amp. did that once.. cost $100 to repair, and i did it installing it for a guy who was buying it from me for only $200... d'oh.

I killed the amp in my deck a year ago(long story, I was an idoit)
Anyways, I just cut the amp chip off the deck's PCB and put it all back together, RCA's work great still, and I can say my entry level deck has no internal amp on it hahaha.

Kev.
