Im building a box for a buddy of mine and the variables that Kicker gives for this sub has such a HUGE range.
Its listed as:
Sealed box volume: 1.0-4.6 cu. ft.
Ported box volume: 1.75-2.25 cu. ft.
If anyone has experience with this sub or a similar one of Kicker and could offer some insight on a ported box that would be great!
