If you want to go with the Mac, you'll have to buy the amplifier and the subwoofer with the housing unit. Quite costly. You're better off getting an aftermarket unit both costwise and installation wise. If you do a search, there are quite a few posts about the JVC unit that does everything but throw rocks. Also look for subwoofer relocation threads to put the sub behind the passenger seat and the amp behind the driver (Shadowman kit, unavailable now but will give you ideas). The holes for the tweeters are in the door and so is the wiring, just no crossovers.
