1000watt rms 2 ohm 15inch subwoofer what would be the best wattage amplifier to pair with this and would it have to be 2 ohm aswell?

is it duel 2 ohm or duel 4 ohm or just a singel 2 ohm sub??? you can run anything from a 1 ohm amp to a 2 ohm amp just depending if you want to add another sub later if your wanting to add 1 later get 1 big enough to run 2 subs so you wount be wasting your money on sumthing you dont need say 5 months from now
