Weird crackling through speakers?
Got my m3 back today, after 3 weeks ( grrrr) and the speakers are doing weird things. Odd cracking noises coming through different ones even when the ignition was off!
Whilst it was away they wrapped the inner door shut near the front door hinge, and I wondered if the wires in there were messed with but they look un touched?
On further inspection the speaker under the passenger seat ( the bass one?) is farting away! Could this have blown and caused the weird crackling?
