Sub box size?

[sorrowfulkiller]

I just got a pyramid pw 1286 hyper pro 4 ohm 12 inch sub and I was wondering how big should a sealed box be for it?

(it's a 1000W)

I can't find any box reccomendations for it... I even checked the manufacturers website. How much power do you plan on sending it? I'm kinda curious as to how it will sound. Pyramid is low grade stuff, but for the price, it would be fun to put like 10 of them in a vehicle of some kind. That would be fun
