OKay guys I know there are a lot of threads out there about the need to replace bose speakers when installing a new HU. I have been getting mixed signals about what is the right way to do it. I know I should just replace the the speakers while I am replacing the HU but money is kinda short. According to this thread I have an L model since I have a 2200 stamped on my HU. That means I don't have to replace the speakers if I buy a new Alpine Flip out monitor correct? Will my factory 6 CD changer, aftermarket subs, and antenna work with the new HU? If someone could clear all these questions up I would greatly appreciate it before I go and screw up my whole entire system.
