First problem - screaming speakers with no off

[tinpot]

Regarding the "loud screaming static noise" issues, have the dealer check the amp. My amp was replaced to resolve this problem.

Sorry, I know this is an old post but doesn't seem like anyone has posted a problem like this since.

Thanks

i had the same problem with my 08 m3. i parked my car in the garage after a drive and came back to close the windows and when i opened the door the speakers were blasting white noise almost at full volume. i just bought the car a month ago and i don't know how to fix it. this is the first time it happens but i wouldn't want to happen again. how much did the it cost to replace the amp? and was it under warranty still bc i no longer have warranty
