Is it better to wire 2 dual coil subs to 1 amp or 2 amps?

Question

Ive got 2 alpine 15 inch subs which have dual coils rated at 4 ohms (4ohm + 4ohm). They are rated for 750w max rms and 2000w max power each. Im looking to get them wired at 4 ohms rather than going all the way down to 1 ohm because i want the better quality, and the longer lasting setup.
Would it be better to get 2 amps rated at 750w rms or find one rated at 1500w rms and just bridge the voice coils. Also would I be able to use one amp that has 2 channels and use both of the channels?

Sorry im still learning a bit about wiring and im looking for amps that would match my subwoofers.

If they are wired in parallel then your total impedance will be 2ohms (if they are 4 ohms each). If you wire them in serial they will be 8 ohms. 2 cabinets at 2ohms each, wired in parallel, would give you one ohm. Wiring them in parallel is how you should wire them.

What really determines how much power you will get is the amplifier. Most amps will not go down to one ohm or you run the risk of blowing them if you do. If you have 2 cabinets at 4 ohms each, put a matching amp on each side so they don't have to work that hard.
