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 L7X reimagines the massive power-
handling 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!

Specifications
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.

Wiring Configuration
L7X-Series subwoofers are made with dual
1Ω or 2Ω voice coils. Both coils must be
connected to a source of amplification. The
Dual 1Ω will provide a 0.5Ω load wired in
parallel or 2Ω load wired in series. The Dual
2Ω will provide a 1Ω load wired in parallel or
4Ω 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
Use 3/4” (1.9cm) or thicker MDF (medium
density fiberboard) 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.
All the cubic feet (L) measurements in
this manual include the displacement of
the woofer. 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, for example the L7X12 design’s
external port dimensions are, using 3/4”
(1.9cm) MDF:
(13” + 1.5” total MDF wall thickness) x (3.5”
+ 1.5” total MDF wall thickness) x
(36.5”) x (1 ft3/ 1728 in3) = 1.53 ft3
Then, add this number to the internal
volume of the enclosure:
3 ft3+ 1.53 ft3= 4.53 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 ensure 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.

9English
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.

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 pre-
assembled 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.
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.

12English
Using a 4mm Allen Wrench, remove the
eight M5x0.8x10mm bolts securing the
Surround Mounting Flange to the Basket
Assembly.

13English
Remove the Surround Mounting Flange
from the Basket Assembly.

14English
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.

15English
From the cone side (top) of the Basket
Assembly, pull the Cone Assembly out of
the Basket Assembly.

16English
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.

17English
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.

18English
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

19English
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.

20English
Secure the Spider to the Basket Assembly
using the eight M5x0.8x16mm bolts.
Loosely start all bolts before tightening.
Torque the bolts to 20in-lbs in the sequence
shown below.
