hifonics hfi12d4

I bought 4 of theese subs hifonics hfi 12d4's. Wondering if anyone knows what size box i can use for theese subs. Im looking to get theese things loud as hell im gonna be running them off a 1200 watt zeusxi amp. So does anyone know what box size theese work best in looking to keep the box size as small as possible any help would greatly be appericated

i tried to find some specs on those but they are not on the web site. they dont look like they need more than a cubic foot each if you go sealed. and since you have the dual 4 ohm version, you should look into getting a second amp if you want to give enough power to each one since you cant wire all 4 to get a 1 ohm load, only 2 ohms or a half ohm. also what vehicle are they going into?

Here is some specs for the subs you asked for.
