Ok i have a 99 with Mach 460 and i am having the worst time trying to figure out how to put an aftermarket head unit in. I got somewhat of a wiring harness which is 2 plugs that come from the original head unit so far. best buy didnt help me and nor did circuit city. can someone point me in the right direction. a car audio place told me i need a output converter for the rear speakers which makes sense in some way so

anyone who has a aftermarket head unit on a 99 mach 460 please help me figure this out. my volume down button doesnt work on my stock stereo and its driving me crazy i need to put this new unit in FAST.
