You are getting 2 of those subs that handle 300rms? It looks to me as if the ratings of the amps you listed are max ratings, that isn't nearly as important as the rms ratings, that is what you should go by when getting an amp to push your subs. Find out what the rms ratings are, only then can an educated suggestion be made.
