Well at a local how a guy had an accord with 4 zvx 15's by skar walled on only an incriminator audio 40.1 at 1 ohm clamped 800 watts per sub.. Had 4 6" aero ports and did over a 153 on term lab.
Really considering doing aero ports in my wall now for a cleaner look and since my explorer is already limited to about 17 cubes gross for 4 15's walled, it would probably be better for the performance..
Question is will 4 6" aero ports be enough? I mean it should be.. It will also be better for the enclosure since I would be able to have double baffle, and back ( maybe) sides..
Lemme know your opinions
