You can't. the mach 460 speakers are different Ohms, you'll end up /w either lower sounding speakers (to much ohms = lower volume) or burned up amps (to low ohms = pulls to much power).
besides, the stock 460 amps are like 2% THD which is a lot of distortion, if you're actually going to replace the speakers in the doors why not just run new wires to the deck. I would only stop at replacing the Head unit... if you do anymore work you might was well go all the way and replaced the wires and amps in the back.
