37Z

I fabricated a sub box out of balsa core fiberglass with a gray gelcoat finish to fit in the same space of the 370Z a couple of years ago. The sub box was a seal sub enclosure designed for a single 8" sub (Alpine SW-84) with 0.32 interior net cu. ft. The net cu. ft. is the interior space accounting for the sub volume. In my sub box, the interior cu. ft. was only on one-half of this space and the other one-half housed the amp and signal processor. The sub, amp, and signal processor was design to be drop in. The power cable, ground, cables, could be quickly disconnected for easy removal. I added some felt under the rear hatch mat to raise it up to be flush with the sub box height.

I recall that the JL8w3v3 sub recommends 0.375 net interior cu. ft. for each sub. Did you have sufficient net interior cu. ft. for the two JL subs? How does the subs sound?
