Installation

Wiring Configuration: The CompC-Series subwoofers come with single and dual 4 voice coils. To connect the voice coils to a source of amplification, follow these guidelines:
Dual voice coil models can be wired in parallel to provide a 2 ohm load or wired in series to provide an 8 ohm load. Make sure your source unit or amplifier is rated at the correct ohm load for operation.
Speaker Wire Placement: When routing the speaker wire, ensure that it is kept away from sharp edges and avoid the possibility of it getting pinched by the trunk. If there is no existing factory hole or accessible grommet, you may need to drill a hole to run the wire. Be cautious not to drill into other wiring or existing mechanisms. Always use a rubber or plastic grommet to protect the wire from damage when running it through a hole.
Series Wiring: Dual 4 Voice Coils = 8 ohm Load
Parallel Wiring: Dual 4 Voice Coils = 2 ohm Load

Box Building Notes

When building an enclosure for your CompC subwoofer, follow these recommendations:

• Use 3/4 (1.9cm) or thicker MDF (medium-density fiberboard) for optimal strength and sound quality. Seal the joints with silicone to prevent air leaks.
• Use the provided template inside the subwoofer’s shipping carton to mark the mounting hole, then cut directly on the marked line.
• Internal bracing is recommended for these designs. Add triangular bracing between each of the larger unsupported panels to enhance structural integrity.

Pro Tip: Consider upgrading your entire audio system by pairing the KICKER CompC-Series Subwoofers with a KICKER amplifier and speaker upgrades. Consult your dealer for more information on these additional products.

Overview

IMPORTANT SAFETY WARNING

• PROLONGED CONTINUOUS OPERATION OF AN AMPLIFIER, SPEAKER, OR SUBWOOFER IN A DISTORTED, CLIPPED OR OVER-POWERED MANNER CAN CAUSE YOUR AUDIO SYSTEM TO OVERHEAT, POSSIBLY CATCHING FIRE AND RESULTING IN SERIOUS DAMAGE TO YOUR COMPONENTS AND/OR VEHICLE. AMPLIFIERS REQUIRE UP TO 4 INCHES (10CM) OPEN VENTILATION. SUBWOOFERS SHOULD BE MOUNTED WITH AT LEAST 1 INCH (2.5CM) CLEARANCE BETWEEN THE FRONT OF THE SPEAKER AND ANY SURFACE. 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.
• The KICKER CompC-Series are the classic that never goes out of style. We’ve introduced our latest technology, Forced Air Cooling™, for maximum efficiency and product longevity from a 20% reduction in heat, while offering 8, 10, 12 and 15 inch subs with a choice of Dual or Single voice coils so that you always have the perfect subwoofer to meet your needs or fit in your vehicle. For peak performance and sound quality, use these subwoofers with KICKER accessories and amps to get the best results.

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 speakers, we recommend using genuine KICKER accessories and wiring. Please allow two weeks of break-in time for the speakers to reach optimum performance.
Pro Tip: You’re a KICKER amplifier and a few cables away from a full system upgrade that will dominate any factory system! KICKER line of amplifiers make it easy to upgrade to solid bass with your existing or stock source unit. Also, ask your dealer about KICKER Speaker upgrades.

Installation

Wiring Configuration

CompC-Series subwoofers are made with single and dual 4Ω voice coils. Voice coils must be connected to a source of amplification. The dual voice coil models will provide a 2Ω load wired in parallel or 8Ω load wired in series. Make sure your source unit or amplifier is rated at the correct ohm load for operation.
The speaker wire should be kept away from sharp edges and avoid the possibility of getting pinched by the trunk. If a factory hole and grommet do not exist or are inaccessible, you must drill a hole through which to run the wire. Be careful not to drill into other wiring or existing mechanisms. Any time a wire is run through a hole, it
is necessary to insert a rubber or plastic grommet to protect the wire from damage.

Series Wiring

Dual 4Ω Voice Coils = 8Ω Load

Parallel Wiring

Dual 4Ω Voice Coils = 2Ω Load

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 CompC 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.
• 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 CompC12 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 ft3 / 1728 in3 ) = .65 ft3
• Then, add this number to the internal volume of the enclosure. 1.75 ft3 + .65 ft3 = 2.4 ft3
• 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.
• You can loosely fill your 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 by making your subwoofer think it’s in a bigger box.

Add triangular bracing between each of the larger unsupported panels

Sealed Enclosures

• 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 CompC-Series 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.

Minimum Sealed

Maximum Sealed

Panel Dimensions for Minimum Sealed Enclosures using 3/4” (1.9cm) thick MDF:

17.25X15.75 [43.8X40]
Panel C in. [cm]| 9.5X9.5 [24.1X24.1]| 12X12 [30.5X30.5]| 13X13 [33X33]| 15.75X15.75 [40X40]

CompC-Series subwoofers perform well in any size sealed enclosure between the Minimum and Maximum volume recommendations. These systems will exhibit benefits of both designs. 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.

Vented Enclosures

These boxes are the enclosure of choice if space is not a problem and you want to get the most output and low freqeuncy extension from your CompC subwoofer. CompC 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.

[41.3]
Power Handling, RMS| 200| 250| 300| 450

The Vented 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 Vented Maximum design has even more output in this frequency band. The Maximum is the largest and most efficient enclosure design.
