Used Bose or Other Components?
 

As I have mentioned, I just picked up a 2003 A4 Quattro 3.0. It does not have the Bose sound system

I am very short of money, but I need a good stereo. Is there such a thing as a used set of components -- like the Bose speakers and head unit? There must be people who upgrade their system and then sell the old components.

ANybody got any advice on this matter?

Thanks so much!

I really like my stock stereo. Better than bose actually.
