Hi I have a 200w mono amp powering a 10" sub and a 45wx4 4 channel amp for 4 infinity kappa speakers. I can get the sub to work okay but when I wire the 4 channel amp in the same way it distorts like crazy except at very low volume.

I wired it like in the pic minus the farad cap and I only had the 2 front speakers wired into the 4 channel when I tested it. I tried changing every setting combination on the headunit and amp and nothing works, I also double checked the wiring on everything, the ground is good and less than 1 foot long.
