You undoubtedly have killer gear going in. I'm very concerned and interested how you're going to make that deep ass sub fit there. Keep going man!
Thank you sir! Actually the setup isn't too pricy. The AudioFrogs are pretty pricey, but you can definitely achieve a good/great sound with a cheaper midbass. The amps aren't Arc's best stuff. They're class D amps, small, and put out good power. I usually bought my amps 2nd hand, and if damaged (seller's not selling good stuff), Arc Audio was more than happy to fix it. Of course there's a service charge. That's why I always stick with 'em. But I could definitely see myself using cheaper speakers to achieve the same, if not better, quality.
Now back to the sub. I called JL Audio to get their feedback. I was curious because they recommend .5 cubic feet... which isn't really much. When you think of a seals box you think of a big ass... box... in your trunk with nothing else in there. Well interesting enough they said .5 cubic feet is OPTIMAL. Anything bigger than that, while feeding more power, could damage the sub. They said anything with 10-15% of the volume is ideal. And with the sub, the volume comes out to .61 cubic feet. Which is definitely achieveable by utilizing that little cubby space and maybe bleeding over a tad. It's harder to get more volume than to decrease it. So I'll shoot for a little bit bigger of a box and fill up additional volume with resin + wood dust + sand + coins.
Tape and more tape.

Here's where the sub will fit. I love how JL tries to help with the install. The speaker will protrude out a tad. Also, I'll be able to take out the bottom shelf... thing... to reach the amps. Looks like I'll need to load up on some 3/4" mdf wood and 48oz fiberglass cloth.
