No sound from stereo

Hi everyone. I just bought a 2005 Ram SLT with the 6 disk changer head unit. The unit appears to be working correctly but there is no sound. I checked the fuses and they are all good. Is this an amplifier issue? If so, wouldn't it blow the fuse?

While driving around today the rear passenger speaker came on for about 10 minutes. Seems like loose connections at the speakers, but all 6? Maybe the harness going into the amp, but not sure where that is located.

Amp is in the dash behind the glovebox.
