I just ordered a stereo from Crutchfield, was wondering if the harness they include for free works with the Mach 460.
yes, it will work but you are going to be connecting everything at speaker level, not pre-amp what that means is that youe head unit is already amplifying the signal and then it's sent to your OEM amps where it's amplified again not the best thing for sound quality or OEM amp long term durability but it will work a better idea would be to pay a few bucks for an adapter designed to plug into the pre-amp outs on your head unit and then to the OEM wiring harness
I did some searching on the forums and found out I needed a METRA 70-5519 harness, so I ordered that.
