I have no experience with the new KS stuff. I mainly install and sell their entry level stuff, which is still great for money. I used to run their old IQ amps, and absolutely loved them, so I have no doubt what they have now is a great product. With that being said, I think it is hard to find power from Kicker products. Most of their amps are only doing 50x4@4.
I would start here for a flat signal:

My sources at PAC say this will soon support a full and complete DSP, and possibly on screen adjustments through the 8.4.
From there, you would just need decent power.
