The mach 460 is garbage. After my cd player stopped working(at all) I took it down to circut city and got a kenwood unit. it sits where the tape deck was and I have a spacer where the cd unit was. I had to take it back cause when they installed the cd player, the door speakers didn't work the the new cd player, in the process I had them put in bazooka 5x7's. The factory speakers are garbage too, so I replaced the rears with poineer 5x7's. And that was a pain in the @ss in itself. You have to lower a tray in the back that holds the amps to access the rear speakers. The system is finished off with a scosche amp and a audiobahn 10" sub. But yes, in my opinion the factory 460 sys must go. BTW I had to replace a blown tweeter in the front(I didn't know you can blow tweeters)with one from the back when I did the speakers in the rear deck.
