I've read a lot of threads/stickies trying to find my answer but am more confused now and am hoping someone can help. I've installed subs in the past using a LOC but this is my first time trying to use high level input.

I have a Soundstream PN1.450D amp that comes with a High Level Input harness with 5 wires.

2 are R'Ch + & -
2 are L'Ch + & -
1 is ground

Am I supposed to hook these up to the pre-amp wires listed below? If so, where do I connect the Ground wire? Thanks

RR+=L
RR-=P

RL+=BR
RL-=Y
