I purchased a complete "Mach" stereo upgrade (sub/amp, wiring harness, grill, head-unit with bad display- which I fixed thanks to this board, btw )from a fellow member. It all came from a 2000 limited supposedly. The sub wouldn't work. After double and triple checking wiring and voltages I decided it was the head unit and bought an Identical one of ebay. Both sellers claimed they were subwoofer head-units, and hey,,, you can see they have the 8 pins in connector 2.
Well, the second amp had no sub output either. Then I found a third unit locally, called the seller, and he said that I had to read the white tag on the bottom of the radio, and If it did not specifically say MACH, there would be no subwoofer output signal, even thought the pins are there.
Indeed, I met with him, plugged in his head unit and the sub worked brilliantly. Indeed, The other two radios said "prem" instead of "Mach" upon inspection. I suspect quite a few used radios on ebay listed as Mach units because the have subwoofer pins are actually only Premium Sound amps. You can't use the black heat-sink and the presence of pins in Block 2 as the only identifiers.
Now I gotta work with what has turned out to be two jerkoffs to get refunded.
Bottom line... for 1998-2000 head-units, insist on seeing a picture of the bottom of the chassis label to verify Mach status, or only deal with somebody trustworthy.
