dual 2 ohm or dual 4 ohm subs

I am about to buy two new Memphis Mojo Tens with a 500 watt rms per sub. Im going to put them in a ported Super Bass box made by Probox. I would like opinions on whether I should buy dual 2 ohm or dual 4 ohm subwoofers. If i buy dual 2 i am going to wire them down to 2ohm and more than likely run an alpine 1000 watt on them.   If i buy dual 4 i am going to wire them down to 1 ohm and put the Memphis 1100 class D on them.               I would like to have opinions on which set up i should run.Two things are infinite, the universe and human stupidity, and im not so sure about the universe.

The only question is, which amp are you going to use.

well if u get 2 ohm subs you limit ur wiring options cuz with 2 or 1/2 most likely your not gonna have an amp that does 1/2 ohm stable. but if you get 4 ohm subs you can always change it up. you can buy big amp run it at 4 ohm for efficiency... wire down to 1 for power and more dbs maybe. or you can buy a 2 channel and bridge the amp. with 4 it just gives you a couple more options.Pioneer DEH-400UB
