77KCK056 amp and Polk DXI Speakers? Enough power?
So I ordered a 77kck056 amp and some polk dxi series speakers, hoping to replace the infinity premium system in my '12. I also have a separate sub amp, and an alpine type R 8" to replace the factory sub. Since the 7th channel on the 77kck056 was designed to run the Kicker add in sub with 200W amp, I figured it would work fine as an output channel to my sub amp, and would make for a minimum of tinkering with the stock components to replace my entire audio system.
Now that I am looking at the spec sheet included with the 77kck056, though, I am wondering if it doesn't deliver enough power for the polks (4 ohm speakers).
From the spec sheet:
RMS Power at 4 Ohms:28Wx8
RMS Power at 2 Ohms:46x8
Freq Response: 20Hz=21kHz
Signal to Noise Ratio: 95dB
THD at Rated RMS Power: 1%
Will this be enough to drive the polk DXIs, or should I return them and just get the 77kick10's this amp was designed to run with? I had seen other people posting that they liked the polks better, and I did the marine rating, but I really don't feel like running under powered speakers.
Interested if anyone has experience with the setup I am hoping to run, or if anyone has tried the polk DXI's with the stock infinity premium amp. Is there enough power? Thanks?

Just installed the dxi650's (BB $50) in the sound bar running factory (infinity) amp. Have the 6500's on the way this week (BB $100) . So far very happy with the results of the sound bar. Filling with polyfil was key. Factory amp pushes them fine for now, but will allow for a little more power if I decide to upgrade. Personally, I've never been a fan of Kickers other than the subs.
