hi everyone! I've purchased 2 alpine e-10 subs, and an alpine 500watt monoblock amp to power them.
I've been doing a whole lot of research and taken a lot of measurements in the trunk. with what I've come up with i used the calculators on this site to design myself this box:
Good Subwoofer Enclosure Design? -- posted image.
the net interior enclosure volume is: 2.35 cu^ft (without subs)
the net interior port volume is     : 0.50 cu^ft
im pretty sure its the biggest box that will fit into my trunk opening..
please let me know what you think, and anything you might change as this is going to be my first custom made box! :)
thanks in advanced,     Patrick.

it looks like it should be pretty good. as long as your specs for the subs and the specs for the box match up then imo it should hit good also. thats pretty bad how you designed it tho. what did you use? and i also have that same  alpine amp on a type s 12, upgrading to an r. its bad tho. just dont mount it to the box. and i like the fact that your flush mounting them

thanks pcana, i used google sketch up to design the box (its free!)
i really like the look of recessed subs too.
any suggestions on where to mount the amp? why not on the box? not too much room in the neon... haha
yes im planning on doing kerf bends, and then filling the gaps with wood glue.
anyone know where i can buy the carpet to cover it with?

1: Gonna hafta look into that Google Sketch Up... Never heard of it, but if it lets you do THAT kind of stuff... that's buh-DASS!!! =)
3: If the amp is small enough, I'd recommend under the seat. I never recommend mounting an amp on a box, unless that box is braced FAR more than you have indicated in your drawing. Those walls are gonna flex and vibe like nobody's business, especially the back and right end! See this thread to give you an idea of proper bracing... By the way everybody, pics to follow soon for the completed setup of that box! Looks sharp, sounds better! The walls are like knocking on stone, and the Gorilla Glue sealed that thing tighter than a duck's butt! No breathing, ZERO flexing...
3: Don't bother filling the kerfs. It won't be necessary. At those dimensions, once curved, and held in place top and bottom, you'll have no strength or flex issues. I promise...
4: Any decent fabrics store in your area should be able to provide you fabric to cover that up!
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Yea, i have sketch up on my flash drive, im just not great on it. and i wouldnt mount my amp to my box because of the rattling and vibrations from the subs. one other thing, just make sure that the port stays the same width all the way through
