[C-Dog 91LS]

Try This

Well I finally got in there and according to Owner's Link the problem was fixed. So why would the AMP go bad in under 4 years?

I have a 91 LS sedan. If you call Matt at Bose, he might help you out. He took care of me when I thought my amp was going bad. Matt Dorin 508-766-9524 Bose Corporation. Give him a call. He'll at least give you a good price on a new one. Good Luck!
