Box Building Notes

KICKER recommends using M5 or #10
mounting screws with t-nuts. Use 3/4"
(1.9cm) or thicker MDF (medium density
fiberboard) or birch plywood and seal the
joints with silicone. Use the "template"
inside your L7X subwoofer'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.
For 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.
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 ensure unrestricted
airflow.
