I called Crutchfield today to find out about speaker upgrades. Unfortunately they did not have any information regarding that question; however, they did tell me they now have a solution for an aftermarket cd changer. I was told the price was $599 including the fiber optic cable. I hope this helps some of you people out. Oh! if anyone has any speaker upgrade suggestions please let me know. I do not want to replace the head unit, but I would like some better sound.
