Subs I will be building this box for is a single 12 ufo mag btl.
My last box was about 2.8cu ft after displacements with 46sq in of port, box was deff on the big side. But never had any problems with it the year I ran it.
Demensions I have to work with, 35w x 13.5h x 22d (the 35 is completely side to side in my trunk, so unless shortened could not do a side port), this will be going in a trunk. Last box was sub/port rear facing, one problem with it was I had horrible rise. With my m3a it went from 1ohm to 5.4ohm, still clamped like 1800w out of it but is besides the point.
If anyone has ideas of diff sub/port configuration or box help would be greatly appriciated.
