My boss owns a 2001 BMW Z3 roadster. He is having trouble with his audio system. I think it's either the amp or a fuse somewhere. What it's doing is the radio plays, cd player works, you can go through stations and songs on the cd and everything but he is getting no sound. Just wondering what you guys thought and where the amp fuses would be located on this vehicle. I know there is a fuse box under the hood and one in the trunk but just wondering if there is an inline fuse as well. Let me know. Just thought I'd help him out with this. Thanks guys!

 

There could be a fuse on the stock amp itself, have you checked there yet?
