I have an 06 TL and since the day I bought it the rear speaker deck buzzez when the bass is turned up to 2-3 and the volume around 11-12. I had the deck replaced years ago when it was still under warranty but I still have the problem. Has anyone else had this issue and if so is there a reasonably easy solution?

 

bring it in to a dealer, pretty sure there is a service bulletin out there for that
