yeah sorry. its a 2002 bmw m3. the radio comes on but nothing is coming out of the speakers. at one point it took a good 5 or 10 mins before it worked but now it has stopped all together

That just sounds like a problem with the radio or amp. I doubt it has anything to do with the dead battery accept maybe accelerating the failure from trying to run it on low power.

yeah i was thinking that it could be a fuse but if it was i dont think that the radio would come on at all. i dont know what to do because i know that bmw dealership is gonna charge too much haha

Repairing a radio is always a losing proposition, regardless of who repairs it.

The normal path here is to just verify that the radio and any separate amp is receiving all the proper power supplies and grounds before you condemn it and then just install an aftermarket radio. It's a lot cheaper.
