WIRING
Solo-Baric L7 subwoofers are available with dual 2 (ohm) or dual 4 voice coils. Both coils must be
connected to a source of amplification. The dual 2 woofer will generate a 1 load if the coils are wired in
parallel or a 4 load in series. The dual 4 woofer will provide a 2 load wired in parallel or 8 load wired
in series. The terminals with the white dots are for the first voice coil. The terminals with solid-red and
solid-black markings are for the second voice coil. See Figure 1.

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.
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.

BOX BUILDING NOTES
Use 3/4” (1.9cm) or thicker MDF (medium density fiberboard) and seal the joints with silicone. Use the
“template” inside your Solo-Baric’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 3.
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 L7S12 vented Minimum design’s external port dimensions are, using 3/4” (1.9cm) MDF: [ (13.25” +
1.5” total MDF wall thickness) x (2.5” + 1.5” total MDF wall thickness) x 22.5”] x (1 ft3/ 1728 in3) = .77
ft3, and add this number to the internal volume of the enclosure, L7S12’s 1.75 ft3+ .77 ft3= 2.52 ft3. See
Figure 4. 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 L7 enclosure with poly-fil
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 exiting the port. The use of poly-fil will slightly
decrease efficiency, but will deepen and extend the low frequency output.

VENTED ENCLOSURE APPLICATIONS
These boxes are the enclosure of choice for outrageous street bass and high performance SPL contests.
If space is not a problem and you want to get the most from your Solo-Baric L7, try one of these ported
designs. You will not be disappointed. Solo-Baric subwoofers will handle massive amounts of power in
any of the recommended enclosures, minimum or maximum. 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 ported Minimum design increases bass efficiency and fits in many space-limited applications.
Although it is the smallest recommended ported enclosure, the output from 30 to 80 Hz will be
considerably higher than that of any sealed box. The Maximum ported design has even more output in
this crucial frequency band. The Maximum is the largest and most efficient enclosure design.

The Solo-Baric generates more sound pressure
than an equivalently-sized round speaker and
excels when used in the recommended sealed
boxes. These sealed enclosure designs give
the smoothest response with increased energy
at the lowest frequencies, 20 to 30Hz. These
designs deliver massive amounts of highly-
accurate bass and can be driven with punishing
levels of amplifier power.
The Solo-Baric high performance suspension
system can operate in a larger sealed
enclosure. This maximum enclosure volume
application is ideal for SQ (ultra sound quality)
installations. The Maximum enclosure generates
a very flat response curve and superbly extends
the sub-bass response.
Solo-Baric woofers perform well in any size sealed enclosure between the Minimum and Maximum
volume recommendations. These systems will exhibit benefits of both designs: Minimum produces
high-impact bass, and Maximum generates low bass frequency protraction. Overall, the system will
sound more like the recommended enclosure design it is closest to in enclosure volume. These
enclosure recommendations have been calculated with the airspace inside the enclosure and include
the displacement of the woofer. All sealed-enclosure airspace should be filled to 50% loose poly-fil
(polyester fiberfill) stuffing. Do not make the airspace greater than the SQ, maximum enclosure volume,
recommendation.
