Hey, guys! New member here. Long time Audi owner, however. So, my wife purchased an 08 Q7 and the day we drove it off the lot the sound was stuck on mute. Did the research, found the multiple amp issues people were having and corrected the leak issue/unclogged drain plugs as there was water on the front passenger floorboard the day after a heavy rain. Inspected the amp and noticed water damage so I tried to clean it up some and reinstalled it. At this point ALL of my speakers still worked...

2008 Q7 Possible C.P. On Bose system.
