Some new stuff has come into play here... My amp does not have the ability to power both subs with enough to make it sound good. So now i am only going to use 1 sub, that solves the powering issue... so now i have the ability to make a ported or sealed box with enough room for either...

I am kind of thinking that i would like to try a ported box.... but i looked at some crap about building one, and none of it made any sense.

thoes are some of the site i was looking at, but none of the stuff is qute clear to me. heres some of the basic stuff i have figured out.

minimum ported box requirements - 1.75 cubic ft
sub displacement - .6 cubic ft
the dimensions of the box itself

the whole thing i dont understand would be to figure out the dimensions of the tube for the ported box, where to put it, how to mount it, and what material to use. Also this whole tuning the sub thing. can someone help me figure out what i need to be doing in order to construct this box... and how to do it...
