Help with Subs!!

[1Phat92Chevy]

Someone Please help!!! I have two MTX Thunder 5000 12" 8 ohm subs and I am goin to push them with a MTX 2160. My problem is I dont know if to put them in a sealed enclosure or ported. I want SQ and SPL (Kinda in between) something thats goin to sound nice inside and I want to be heard. If I go with a sealed what air space should I go with, and if I go with ported how many cubes do I need and what should I tune the box to. Just give me your opinion. oh yea they are goin in a 98 mallibu and the link below is the specs on the subs. Thanks for the help! Brandon

well does that amp have a ssf? If you want to be heard then you gonna have to give up some sq and just port the box to like 35 or something but you rnot gonna get tons of bass out of those subs.
