none of those amps are going to give you the power you have stated at those impedances. the hifonics will give you it's 600rms at 1 ohm, at 2 ohms it will deliver 300rms.
the kenwood is listed at 500rms at 2 ohms, and i doubt it even reaches that. basically, your amp choices with those subs will leave you underpowerded and wanting more.
