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
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, 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.

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.
