So I picked up a 01 m3 a few weeks ago. The old owner had wires for subs it looks like in the trunk. Well my buddy was pulling a hockey stick out of the car and all of a sudden my speakers went out.

The radio works just fine, just no sound at all. It’s the navigation unit if that makes any difference.
I’ve scoured the forums and read everything I could. Tried pulling the fuses, even the fuse in the amp. Tried disconnecting the battery but nothing.

Don’t really know what’s going on. Only thing I could think of is that the wires from the sub setup touched and shorted the amp somehow? I’m so confused and am going crazy.

Also in the pass through in the trunk, there is this random wire plug just hanging there, what the heck is it for? Can’t find anything it connects to.

Thanks guys!
