i had the weirdest thing happaned 3 weeks ago. i heard a VERY loud sound like thunder on the rear speakers and whole sound system gone; will not even hear door chime, seatbelt warning or any audio plus bluetooth gone dead too. I could not find the time to run it to local dealer so i drove it like that for 3 days. everything else works great.
After three days all the system back working full power no issues.

Woke up to go to work couple days ago found out that passenger ( front right door only) and back doors speakers are mute. Rear speakers have 50% less power than used to be. Under seat subs are not as powerfull.
Took it a mechanic ( dealer booked for long) diagnosed it and he said there is no problem anywhere in the car with the exception; it is between amp and main dash unit. He mentioned that Amp works great, dash unit works well too. Also mentioned that there is some sort of interfering out from indash unit, if thats mean anything.
This is as weird as it gets, any input greatly appreciated.
