I agree with aaron, even their aftermarket stuff is shit. The subs are pretty decent, but speakers suck major. My buddy had brand new reference series and they blew out on the stock headunit. Anyway off topic, but yea they do have aftermarket cd changers that work with stock headunits, even fm modulated ones but thats a sloppy install imo.
