holy **** man... im getting a 12w6v2, but witha jl 500/1 amp (you baby / jk) and im getting a ported box. the w6v2 will already have pleanty of sq, and if im putting it in my trunk i wanna make sure i can hear it. on the jl website it will tell you the specification of the box, but on a ported box it recommends 1.25 - 1.75 cubic feet of space, and on a enclosed i think its 1-1.5
i think the ported would overall sound better, but if you getting 2 or something space can become an issue. heres what i would say.... if you going with a sub, you want something beyond normal speaker bass, and you want it loud. might as well get a ported, ported is MUCH louder. plus if you going to get an enclosed in the future for both, then you should DEFINITELY get the ported just to test it out.
