Thanks LLoyd, I'm the third owner, but my car has speakers in the lower front and rear doors, tweeters in the A post up front and subwoofers in the deck. There is no mention of Bose anywhere on the factory unit and the subwoofers have the statement on the magnets (looking up from inside the trunk) "high quality Mercedes Benz speakers". Will keep your info in mind and will do a little more research before charging into the system. Thanks for the reply. I will post new info if I can.
