I've got a 2000 sls with delco sound system and I'd like to know if it's possible to upgrade to Bose. I know from reading, that switching only the h.u. won't work. I do have access to every component of the Bose system. Is it possible with having all components? I know this topic has been discussed but I can't seem to find any stories of success, or anything much deeper than a possible h.u. swap. Thank you in advance.
