It depends on the subs you are using.
find an amp that matches up with the impedance that your subs have. So if both subs are 8 ohms (or dvc 4 ohms) each find an amp that can put full power into a 4 ohm mono load or if the two subs are 4 ohms (or dvc 2ohms) each then find an amp that can puts full power into a 2 ohm mono load. there are single channel amps and 2 ch amps that are available that can run at those loads.
If you want to run a four channel , thats an option as well so long as the amp is bridgable. If the subs are 4 ohms then bridge 2 channels of the amp to each sub . if the subs are 8 ohms then run both off the rears bridged and run the mids/highs off the front channels.

like stated... it depends on the subs.. but for a general rule.. a class D amp is better then a/b amp. so a mono one.. would be better.. it would drawn less power an put out more.

A class D amp is only better for effitiency thats it , class A/B is way better for sound quality.

does it have dual 4 ohm coils or dual 2 ohm coils?
Assuming the amp is stable at 2 ohms stereo ( 4 ohms bridged) and that you are using ONE sub (you didnt say if you were using more than one) .
If the sub has two 2 ohm coils, then wire the coils in series to get a four ohm load and run the amp bridged to the sub. If the sub has two 4 ohm coils then run it series to a 8 ohm load and bridge the amp to it, with this set up tho you will only be getting half the power of the amp, because its running at 8 ohms bridged.
