Can someone tell me?

What wiring Harness is needed for my 98GT. I have the double Din 460. I want to install a Alpine CD player, use my Mach 460 amps to power all the stock speakers & use the Alpines rca cables for my sub. Is this possible?

Metra's 70-5510 would do the trick. Metra Electronics - Fit Guide Punch in your vehicle, select Harness - into car and it should pull up a list with the 5510 in it and tell you what it does.
