Do you have a Bose system to put in or would you have to find one?
I have never even heard the Bose system so I don't know if it would be worth pursuing or not, but I would think, and someone correct me if I'm wrong, that if you are going to go to the trouble of replacing the stock set up, that you just as well go with other aftermarket brands, buffet style pick and choose the different parts you want, head unit, amps, speakers, sub, etc. Build a system that is unique and specific to your ride and your preferences.
