Why would you want to do that? I have the Mach 460 in my car disabled. I replaced the 6 disc in dash with aftermarket deck and the front mids and highs with Diamond Hex. The rear amps and speakers are unplugged and just in the way, I would have taken them out but it's a pain.
The speakers are cheap paper cone and the amps are under powered. It would be worth your time to save up and get good after market equitment. Even low end pioneer 4x6's sound better than the factory stuff.
Just my opinion though...
