Well i was talking to a local buddy and im trying to make the box as small as possible So he suggested maybe 2 8.1's and roughly 4.5-5 cubes per sub with around 100 sq inches of port tuned to 33-36hz
whats ur input drew?
and ill map out electrical for you. 2 300 amp alts, Stock alt. 8 runs of 1/0 + and 8 runs -, 7 D3100's, 6 in the back one up front. I figure ill be pulling close to 1400 amps of current constantly with the stereo full tilt.
And lots and lots of deadener.
