Has anyone else experienced a full volume screetch out of the left front speaker for no reason at all? After turning the car off then back on 2 hours later I nearly lost my left eardrum.

At 0 volume no noise. At +1 full blown screetching. Left side. Turning the car on and off a couple of times didn't fix it. Then a 10 minute drive, turning the car off, and restart 1/2 hour later everything is working fine. Great, looks like it is going in again. Well at least the spring return on my ebrake will finally get fixed as it snapped.
