You need more port. And I dont know what your tuning freq is but it looks like its gonna be quite high with ~1 cuft per and not a very long port.

Its the sort of thing you do long before you build the box - it has to do with the overall length of the port, and the way that looks youre gonna be using those CVXs as midbass.

It can be remedied, but you have difficult space constraints.

this link will tell u exactly what u need to know http://mobile.jlaudio.com/support_pages.php?page_id=165
http://www.caraudiohelp.com/subwoofe...e_software.htm
http://www.kicker.com/sites/default/...2006CompVX.pdf

Use 3/4” (1.9cm) or thicker MDF (medium density fiberboard) and seal the joints with silicone. Use the
“template” inside your CompVX’s shipping carton to mark the mounting hole, then cut directly on the
line. These designs need internal bracing. Add triangular bracing between each of the larger
unsupported panels. See Figure 4.
All the cubic feet (L) measurements in this manual include the displacement of the woofer. For the
vented enclosures the displacement of the port must be calculated and added to the internal volume of
the final design. Use the outer dimensions of the port and multiply “X x Y x Z”, convert to cubic feet, for
example the CVX12 vented compact design’s external port dimensions are, using 3/4” (1.9cm) MDF:
[ (2.5” + 1.5” total MDF wall thickness) x (12.5” + 1.5” total MDF wall thickness) x 20”] x (1 ft3 / 1728
in3) = .65 ft3, and add this number to the internal volume of the enclosure, CVX12’s 1.75 ft3 + .65 ft3 =
2.40 ft3. See Figure 5. Due to the necessary length of these ports, you may want to fold the port along
the bottom and back walls. It will be impractical to use round ports for these designs.
Do not install a port opening against a solid surface, such as an internal brace, back-panel or trunk wall,
seat or interior panel of your vehicle. The port opening must remain unobstructed. Use the smallest
dimension of the rectangular port as the minimum amount of space between the port opening and any
solid surface to insure unrestricted airflow
