Owner's Manual

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", then convert to cubic feet. For example, the
CVT12 Vented Minimum design's external port dimensions are, using 3/4" (1 .9cm) MDF:
(12.5"
+ 1 .5" total MDF wall thickness) x
(2.5" + 1 .5" total MDF wall thickness) x
(20") x (1 ft

Then, add this number to the internal volume of
the enclosure. 1 .75 ft

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.

If you prefer an ultra-smooth bass response, you should loosely fill your CompVT enclosure with poly-fil
stuffing. Vented 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 exiting the port. The use of poly-fil will slightly
decrease efficiency, but will
deepen and extend the low frequency output.

Sound Check: Poor bass response? Check the system phasing by reversing the positive and negative
speaker connections on the subwoofer. If the bass improves, then the subwoofer was out of phase in
reference to the rest of the audio system.
Note: All specifications and performance figures are subject to change. Please visit www.kicker.com
for the most current information. To get the best performance from your new KICKER Subwoofer, we
recommend using genuine KICKER Accessories and Wiring. Please allow two weeks of break-in time for
the
subwoofer to reach optimum performance.
If mounting in trunk space or other compartments of the vehicle, pay attention to cable lines, trunk
springs, hinges and seat mechanisms that could cause problems with the operation of the vehicle
or
stereo system. Carefully lay the stereo system cables; pay attention to seat fasteners and other items that
could harm the cables.
WARNING: KICKER products are capable of producing sound levels that can permanently damage your
hearing! Turning up a system to a
level that has audible distortion is more damaging to your ears than listening
to an undistorted system at the same volume level. The threshold of pain is always an indicator that the sound
level is too loud and may permanently damage your hearing. Please use common sense when controlling
volume.
