The other night I got into my car after work and had no music. The stereo was working (the display was lit, I was able to change stations and change from tape to cd to radio), but there was nothing coming from the speakers. I have a 2003 A4 with the Bose stereo with the in dash cd changer. I checked the radio fuse which was fine. Is there another fuse somewhere, possibly on the back of the head unit? I would rather fix this myself than take it to the dealer. Thanks for any help.

 

Got me stumped. You try turning up the volume! [:-]j/k

You have'nt done anything with the stereo or electrical system? The only thing i could think to do is either check the radio/amp for a fuse, or fuse panel for an amp fuse.

 

The stereo/electrical system is completely stock. The only fuse I found that I found for the radio was still good. I attempted to get to the back of the head unit to see if it has a fuse on the back of it, but I couldn't get the stereo out of the dash, and I couldn't get behind it either. I'm not sure where the amp is in this car. I'm frustrated as hell!

 

The Bose amp is in the trunk, right? Maybe check that. Another thing to try is to pull the radio fuse for a few seconds, then put it back in, to "reboot" the radio.
