i have a deh-7800 pioneer cd player and i took it out of my grand prix yesterday and went to install it in my new 1991 firebird...everything is hooked up right cuz me and my friend have done many of them including the one in the grand prix, and we checked to see if any fuses are blown and they werent,and the cd player wont turn on at all!!! i no its not fryed cuz ive only had it for a month and it was working when i pulled it out of the prix
if its got power and the cd player is not working... then its the HU. Theres no separate power supply just for the cd. Red wire run to a power source? Black wire to a known good ground?
so fuses arent blown? u checked the ground? all the wires are correct? wont turn on? sounds like you some how fried the internals. that happened to me and now my HU is in the shop.
I believe you can fry your H/U when installing into a car with a factory amp. Do you know if your firebird has a factory amp? Did you use a wiring harness or just hook up the wires?
like marc said, hook power wire to a known good power source and ground wire to a known ground and see if it works then...to make sure its not something in the cars wiring
