Driver Rear speaker is blown
The dealer ( Ferman Chevy Brandon) is unwilling to replace the speaker under warranty
I isolated the rear driver and compared it to the rear passenger speaker and the driver side sounds horrible. The service manager admitted it sounds bad but said if I listed to normal music it wouldn't rattle... I don't have $ to upgrade the system...... They gave me a notice from GM that rattling in the boston premium audio system is normal, but why is only the one speaker doing it? What do I do?
