Or you could just bypass the bose amp and not worry about it. But that would depend on if it is an RDS (databus hardwired) or not. My 01 was not, so I forwent the harness and lost the door chimes and OnStar, just bypassed the amp.
That would kind of defeat the purpose of having the Bose system. Maybe if he added a cap it would help?
