I tried to design a box on this program but... im not sure if these dimensions will work very well at all.
it should be about 3.5ft^3 total minus the ports and 5/8 wall divideing the subs.
I was planning on putting to cvr 12's in it.
i've built a couple boxes before, but this is my box so i want it to be good and figured i should check with the pros.
its going in my prizm and i have about 16 1/2 between the speaker magnets and the floor of the trunk and 42" inch limit on width so im shooting for bout 15"X38-40"X x"
