Factory Bose radio turns on and seems to play according to the flickering FM light in the radio display, but no sound is comming from any of the speakers.

It was working fine for a few days after I replaced two bad speakers/amps. What could cause all 4 speakers not work all of a sudden? A relay? Shorted wire? Bad ground?

I had to reconnect all the wires in the stock radio harness back together due to a previous external amp (ghetto-rigged) hackjob.

Thanks.

You probably blew the amp fuse. It's located in the fuse box underneath the dash over your right knee when sitting in the car.

 

Id also check the ground.. same has happened to me before, stupid things happen with those damn cd players

 

Might as well just check the wires to...
