2 ohm dual voice coil subs and you need to provide EACH of them with 750 watts, meaning if you want to use ONE amp to power the both of them, you'll need an amp that can push 1,500 watts RMS....NOT PEAK

you can pretty much just forget about that peak rating.

so, do you want to power them BOTH with one amp, or can you affort two amps, one for each sub?

I'd wire each sub in series for a 4 ohm load, then wire both subs together in parallel to create a 2 ohm load. Then, find an amp that will give you as close to 1,500 watts at 2 ohm.
