was that box made for thoses subs? see the problem with putting subs in a ported box is that the box needs to be built for the spec of that sub. when the box is sealed its a differnt story. but if you have 2 subs that call for 3 cubic ft and u have them in a 4 cubib ft box. its gonna sound like crap and distored and your gonna end up blowing your subs.( MY statement is not refering to you im just saying in general ) but unless you get the rigt box for those speakers dont turn that amp up your gonna fry the coils.
