Does the 01 come with 2 different decks, or one big one? Mine has the Mach 460 6 disc in it. I don't want to rewire the hole system because I like the fact that I have the 8 speaker mach system. I just want my pioneer 9300 headunit in there to help with the lows for my subs. I already have it bought so it's just sitting around waisting the 4 year warranty on it. Been sittin since December. If I rewire it, how do I still use the door tweeters, and back tweeters. Do they have there own channel on the stock deck, or does it just tap into the door speaker wiring.
