i am trying to plan my next system but have never done a ported box. my question is i am trying to fit 2 12's or 10's in the trunk but have some what limited space. the box can be no longer then 32 inches and no taller then 15 do you think i could do a ported box like this to fit two of these subs. the will be firing through the fold down back seat. also does the port have to fire forward also like the speakers if the trunk is sealed. sorry for all the questions but i am having a hard time figuring this out.
