2 radios no sound?

[Sniper82]

I had one CD player in my 92 firebird and it worked fine till I got no sound one day even though it powered up like everything was fine. Well I figured I blew the amp in it or something so I bought another one and still the same thing. Powers up but no sound. What would cause this? Surely all 4 speakers ain't blown? I don't listen to music that loud.

One way to see if it your speakers is to unhook one and use another one in its place and see if it will work. I can see them all ggoing at once but I have seen some stranger things happen like both headlights blowing at the same exact time.

Even a blown speaker will still play usually, but it will sound terrible. I've only seen one speaker that wouldn't play at ALL. One of the factory rear deck speakers in my Prelude was so badly shot that the woofer had completely separated from the voice coil, breaking one of the wires.

Your car uses a radio with internal amplifiers. There's no external amps. Only thing I can think of would be two bad radios (although unlikely).

Perhaps your wiring developed a short somewhere, causing the radios amps to pop as soon as they are powered up?

probably a short. Get an extra speaker, or pull one of the stock ones and hook directly to the new headunit.

fuse?

I'll try some of this out later today.

yeah i was thinking the fuse too. My gf had the same thing happen to her. There was a fuse in the line to the Deck, or on the deck I cant remember.

But if a fuse goes, then it won't power up at all? OP said that the decks power on, but don't have any sound. AFAIK, there's not a fuse that only runs the internal amplifiers....

broken speaker wire.

never ran into that b4, odd.... I'd connect a separate speaker to one of the outputs, disconnecting all other speakers and see if you get sound out of that one
