Sub Amplifiers, Mono or 2-channel for dual subs?

[Destructo]

Found the box I want, its very similar if not the same one that another member has, dual 10" box with a amp rack in the middle.

Now onto the real question. For the amp should I go with a Mono sub amp and run it at 2 ohms for both subs or get a 2 channel amp? I'm looking at the Sony 2200GTX which is 200wx2 @ 4 ohm or the Rockford Fosgate Punch P3001 which will do 150x1 @ 4 ohm or 300x1 @ 2 ohm, which I think I can run two subs and have the amp run at 2 ohm and get 150w to each sub. The subs I was looking at are rockford Fosgate Punch subs which handle 150w RMS. I know the Rockford subs may not be the best but they seem to be pretty decent and they will work well with the box I have chosen.
