HunterJohnson Posted April 13, 2013 Report Posted April 13, 2013 DAmoreEngineering 1 month ago If the head unit has SE outputs and the amplifier has SE inputs = coax cable If the head unit has SE outputs and the amplifier has Diff inputs = twisted pair If the head unit has Diff outputs and the amplifier has Diff inputs = twister pair If the head unit has Diff outputs and the amplifier has SE inputs = bad no matter what as you will shorting out half of the head unit's outputs. In this case you would need an amplifier with Diff inputs or a converter to convert the head unit's outputs to SE Edit: also was wrong about the pioneer deh 80prs it is coax not twisted. just went to car and double checked Are you sure I tested and didn't get any resistance Scion tC SQ BuildiPad mini, lots of fabrication, daily drivenFord Explorer C Pillar Wall Build Just a cheap car to destroy with bass

Thanks for explaining, I was doing it wrong. So how would u check for amps? Ground of batt to ground of RCA?

LordArcane Posted April 13, 2013 Report Posted April 13, 2013 i just got done making 2 videos going into detail on how to test amps, and head units. i will be posting them up shortly

LordArcane Posted April 13, 2013 Report Posted April 13, 2013 not a problem, took me a min to get it but really it is so simple i think thats why so many are getting confused. like me they were probably overthinking it
