Sound quit coming from speakers. Radio fuse OK. All lights work on radio. Any ideas. Also, how is the radio removed?

The Amp in the trunk might have blown,

Check the fuses

could be the speaker out put has come loose at back of radio as to have all speakers blow at once is just to much of a coincedence so pop the radio out and check wiring connentors if all ok looks likely the radio is needing replacing

My FM band stopped working. AM and casset still worked. Found parts car, replaced radio, all is good. The FM display still worked-no sound.

If the radio powers on, the fuse is OK. You probably have a bad output section in the radio.

Look in the trunk and see if anything is touching the speakers.

My van radio runs on 2 different fuses- both in the fuse box under the dash. One runs the lights the other the sound. Hope this helps.

First my 2006 Aveo radio quit so I replaced it. Then about 5 months later 2 out of 4 of my speakers quit. My after market radio dealer patched things so the 2 speakers that still work are able to function. "The fix" is to replace a pair of speakers. I have 1 front and 1 rear speaker blown.

speaker noise in car at all times even with key off,Radio does not work,Goes away when removing radio fuse or power door lock fuse.Does not quit when radio is unplugged including speaker wires.

I think that the problem is in the connection between the cd-player and the radio antenna on the roof.
