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 2 INCHES (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 L7X reimagines the massive powerhandling and motor of KICKER's legendary line of L7 SoloX subwoofers with the most up-to-date engineering, materials, and design concepts. If you want the absolute best in SPL-performance and rock-bottom bass, then look no further than KICKER's award-winning pedigree with this celebrated line of subs. And remember that the driver is only half the equation. Without the immense power needed to push these subwoofers, you're short changing yourself. Use these subs with our high-powered Warhorse amplifiers to crush the competition and get all the low frequency output you're looking for!

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
L7X-Series subwoofers are made with dual 1 or 2 voice coils. Both coils must be connected to a source of amplification. The Dual 1 will provide a 0.5 load wired in parallel or 2 load wired in series. The Dual 2 will provide a 1 load wired in parallel or 4 load wired in series. Make sure your source unit or amplifier is rated at the correct ohm load for operation.
The subwoofer 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.

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, backpanel 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.
English

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.
English

Add triangular bracing between each of the larger unsupported panels. The mounting baffle should be double the 3/4" wall.

Vented Enclosures
L7X subwoofers will handle massive amounts of power. Vented enclosures increase bass efficiency and have significantly more output from 30 to 80 Hz. Output will be considerably higher than that of any sealed box. Do not forget to add the displacement of the subwoofer to the internal volume of the final design.

Re-Cone Kit
The L7X has been designed for competitive use and, because there is no glue utilized in the re-cone process, the cone can be replaced in minutes if failure occurs in the field.
The Re-Cone Assembly consists of a preassembled cone, surround, and voice coil that will be bolted into the L7X motor and Basket Assembly, and can be purchased on the KICKER website here. Do NOT attempt to use alternate impedance Recone Kits when rebuilding the subwoofer. For example, only use the 1-ohm Recone Kit in the 1-ohm L7X subwoofer structure.
Use the following steps to rebuild the L7X.
Do not use power tools for this rebuild! The L7X magnet is extremely powerful and may cause personal injury or damage to items. Use caution around objects that contain magnetic material.
Begin by removing the subwoofer from its mounting location and disconnecting all wiring.

Using a 4mm Allen Wrench, remove the eight M5x0.8x10mm bolts securing the Surround Mounting Flange to the Basket Assembly.

From the magnet side (bottom) of the Basket Assembly, use a 4mm Allen Wrench to remove the eight M5x0.8x16mm bolts securing the Spider to the Basket Assembly.
English
14
From the cone side (top) of the Basket Assembly, pull the Cone Assembly out of the Basket Assembly.
English
15
Clean and remove all debris from the Voice Coil Gap.
NOTE: The L7X magnet is extremely powerful. Do not allow objects containing magnetic materials to fall into voice coil gap. These objects may become stuck, rendering the subwoofer useless.
English
16
WARNING! The Voice Coil Alignment Pins are very sharp and may cause serious injury or death if handled improperly. Use caution while handling.
With the Basket Assembly laying on its side, insert a Voice Coil Alignment Pin into each of the eight holes of the subwoofer motor. The pin's head must contact the motor. Finesse may be required to achieve contact.
English
17
After all the Voice Coil Alignment Pins are inserted, push the pins towards the magnetic pole until the pins are held to the pole magnetically. Space the pins evenly around the pole.
push the tips of all 8 pins towards the magnetic pole in the middle until they are held in place
English

With the Basket Assembly still laying on its side, insert the new Cone Assembly into the Basket Assembly. Pay close attention and ensure that the pins lay inside of the voice coil, allowing the voice coil to smoothly slide into place over the magnetic pole.
