1) You need an amplifier rated at least 1500 watts rms at 1 ohm, and preferably closer to 2500w rms at 1 ohm.
2) That much power will definitely require a high output alternator and a "big 3" wiring upgrade for your vehicle, which won't come cheap.
3) A logical and intelligent person would realize that two of those subs is overkill and would just run a single sub at 2 ohms and use an amplifier rated 1000-1500 watts rms at 2 ohms. Even then, a high output alternator and big 3 upgrade is recommended.
4) An even more logical and intelligent person would sell those subs and choose something with a moderate output that won't stress the car 's electrical system or require an expensive amplifier or upgraded wiring and alternator.
