Is this all info on the subs? Are you sure they are just 2 ohm subs? Could they be dual 2 ohm subs or in a pre fab box wired to to 2 ohms? Please be more specific.

Yes it says you have two 2 hm dvc subs in a box right there in your first sentence. My bad.

It seems you have a mis-matched setup. I would wire the subs so that they present two, 4 ohm loads at the amp (each speaker wired at 4 ohms). this will give you 300 watts per channel, per sub then.

This amp does not mention anything about it being stable at 2 ohms bridged. I would not try it either.

That amp requires a minimum 4-ohm load when bridged.  The wiring diagram posted by baley will cause the amp to shutdown (or smoke.)  dwarren's suggestion is correct, or wire all four voice coils in series for a total 8-ohm load and bridge the amp for the same net effect.

Wiring as in the last diagram above will give you the exact same amount of power to the subs as running in 4-ohm stereo and will use less speaker wire.  With your speakers you cannot wire in 2-ohm stereo nor in 4-ohm mono, unless you want to cut the power handling capability of your speakers in half.
