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.

Sound Check: Poor bass response? Check the system phasing by reversing the positive and negative spooker connections on the subwoofer. If the bass improves, then the subwoofer was out of phase in reference to the rest of the audio system.

WIRING

Use the push terminals to wire your subwoofer in series or parallel.

L7 subwoofoers are available with dual 2Ω (ohm) or dual 4Ω voice coil. Both coils must be connected to a source of amplification. The dual 20 woofer will generate a 1Ω load if the coils are wired in parallel or a 4Ω load in series. The dual 4Ω woofer will provide a 2Ω load wired in parallel or 8Ω 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.

Dual 2Ω Voice Coils = 1Ω Load Dual 4Ω Voice Coils = 2Ω Load

Paralleled Wiring Series Wiring

Pro Tip: With a KICKER IQ amplifier, a pair of KICKER GS speakers, and a few KICKER cables, you're looking at a full system upgrade that will dominate! KICKER amplifiers and accessories make it easy to upgrade with your existing or stock source unit. Ask your dealer about KICKER amplifiers and speaker upgrades to complete your system!

Paralleled Voice Coils, Woofers in Parallel

Dual 2Ω Voice Coils n Dual Subwoofer configuration = 0.5Ω Load
Dual 4Ω Voice Coils n Dual Subwoofer configuration = 1Ω Load

Series Voice Coils, Woofers in Parallel

Dual 2Ω Voice Coils in Dual Subwoofer Conf. guration = 2Ω Load Dual 4Ω Voice Coils in Dual Subwoofer Conf. guration = 4Ω Load

WARNING: If you are using multiple subwoofoers that are wired in series to one another, each subwoofer must be in a separate chamber. If not, the subwoofoers could become damaged, resulting in loss of warranty.

SEATED ENCLOSURE APPLICATIONS

The L7 generates more sound pressure than an equivallently-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, 20Hz-30Hz. These designs deliver massive amounts of highly-accurate bass and can be driven with punishing levels of amplifier power. The high performance suspension system can operate in a larger sealed enclosure. This maximum enclosure volume application is ideal for ultra sound quality installations. The maximum enclosure generates a very flat response curve and superbly extends the sub-bass response.

L7 woters 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 wocer. All sealed-enclosure airspace should be filed to 50% loose poly-t (polyester fiberfill) stuffing. Do not make the airspace greater than the maximum enclosure volume recommendation.

VENTED ENCLOSURE APPLICATIONS

These boxes are the enclosure of choice for courageous bass, so it space is not a problem and you want to get the most from your L7, try one of these vented designs. L7 subwooers 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 vented minimum design increases bass efficiency and fits in many space-imitd applications. Although it is the smallest recommended vented enclosure, the outo from 301 Iz-80 Iz will be considerably higher than that of a seaed box. The maximum vented design has even more output in this frequency band. The maximum vented enclosure is the largest and most effi cant design,

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 L7's shipping carton to mark the mounting hole, then cut directly on the line. See Figure 1.

Tnees designs need internal braing. Aod trangular braing between each of the larger unsupported panels. See Figure 2.

D = 3" × 3" for 12L7, 15L7
D = 2" x 2" for 8L7, 10L7

All the cubic feet (1) 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 vent and multiply XxYxZ^ , and convert to cubic feet, for example the 12L7 vented Compact design's external vent dimensions are, using 3/4" (1.8cm) MDF:

[(13.25^ + 1.5^ MDF wall thickness)× (2.5^ + 1.5^ MDF wall thickness)× 22.5^ ]× (1ft^3 / 1728in^3) = .77ft^3

Add this number to the internal volume of the enclosure. The 12L7 is:

1.75 ft² + .77 ft³ = 2.52 ft³

Due to the necessary length of these vents, you may want to fold the vent along the bottom and back walls. It will be impractical to use round vents for these designs. Do not install a vent opening against a solid surface, such as an internal brace, back panel or trunk wall, seat or interior panel of your vehicle. The vent opening must remain unobstructed. Use the smallest dimension of the rectangular vent as the minimum amount of space between the vent opening and any solid surface to insure unrestricted air flow.

If you prefer an ultra-smooth bass response, you should loosely fit your L7 enclosure with poly- I 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 fit from exiting the port. The use of poly-I will slightly decrease efficiency, but will deepen and extend the low frequency output.

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.

IMPORTANT SAFETY WARNING - PROLONGED CONTINUOUS OPERATION OF AN AMPLIFIER IN A DISTORTED OR CLIPPED MANNER CAN CAUSE YOUR AUDIO SYSTEM TO OVERHEAT, POSSIBLY CATCHING FIRE AND RESULTING IN SERIOUS DAMAGE TO YOUR COMPONENTS AND/OR VEHICLE.
