deck has power, but nothing from the speakers

While listening to the radio the speakers all at once cut out. The sub continued to play. It's on a separate amp. So I figured the amp in the deck had failed. When I installed the new deck I had the same problem: the deck has power, but the there's nothing to the speakers. I don't think my car has a factory amp, but maybe it does. If so can anyone tell me where it may be, or give another solution.

Thanks.

Check for a blown speaker (or speaker wire) that is shorting to ground. Just one will disable all the speakers, it's a protection circuit that many new head units have.

,... Yes it is.

And wouldn't it have to be one of the ones under the dash,... After pullining the speaker wires one speaker at a time I found that the 4x6 on the passenger side was the one shorting it out.

So now I have a neww head unit, and soon I'll have new front speakers too!

ive never seen a speaker fail like that. Thanks for the help!!
