Box Building Notes
A Note on Power Handling Capacity
Comp subwoofers will handle large amounts of power in any of
the recommended enclosures, sealed or vented. The smaller
enclosures are best for use in limited-space applications. The
larger recommended enclosures will yield slightly more bass at
the lowest frequencies. The infinite baffle (free-air) mounting
method will handle moderate amounts of power and take up less
trunk or passenger space.
The cardboard “Template” inside your Comp’s shipping carton
can be used as a pattern for cutting the speaker mounting hole in
your enclosure. The cardboard template is the same size as the
Comp basket. After marking your baffle with the template, make
sure to cut directly on the line. This will maintain the proper baffle
cut-out size for the Comp basket.
All the cubic feet numbers given in the following pages include
the displacement of the woofer. For the ported enclosures the
displacement of the port must be added to the final design.
Always use 3/4" (1.9 cm) or thicker MDF and make sure all the
joints are fastened and well sealed. The peak pressure in a
ported box can exceed that of a sealed enclosure. All of these
designs need some internal bracing. Add 2" x 2" (5 cm x 5 cm) to
3" x 3" (8 cm x 8 cm) triangle braces between each of the larger
unsupported panels.
Kicker recommends using a high-grade wood glue and silicone
sealer for an airtight box.

Note: If you prefer an ultra-smooth bass response, you should
loosely fill your Comp enclosure with poly-fil (polyester fiberfill)
stuffing. Ported designs will require covering the end of the port
(located inside the box) with grill cloth, chicken wire, or expanded
metal to prevent the poly-fil from being blown out of the port. The
use of poly-fil stuffing will slightly decrease efficiency, but will
deepen and extend the low frequency output.
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 or the diameter of
the round port as the minimum amount of space between the
port opening and any solid surface to insure unrestricted airflow.
