Coax/Twisted Pair. What do I need?

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

Just a cheap car to destroy with bass :D

Double Checked again, also made video. pretty easy, - lead in main ground, check to make sure head unit shares this ground (if it doesn't you might have ground issues), then check outer ring of RCA outputs on head unit.

does this with RCA's hooked up or not, do not need it powered on as it deals with the grounding side of things.

Thanks for explaining, I was doing it wrong.

So how would u check for amps? Ground of batt to ground of RCA?

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 :)
