owner’s manual
Congratulations on your purchase of a JL Audio subwoofer component. Your JL Audio subwoofer is a
precision loudspeaker which has been engineered to produce the highest quality sub-bass performance
in your vehicle. Authorized JL Audio dealers have extensive technical information for many different
applications of your new speaker. They also have the knowledge, skills and tools to build a high-quality
enclosure that will maximize the performance of your speaker. We highly recommend that you have your
enclosure built by an authorized JL Audio dealer.
Inside you will find specifications and two recommended enclosures for your speaker; one is a sealed
enclosure, the other is a ported design. Both types of enclosures will give you excellent sound quality and
low-frequency extension. The sealed enclosure is a better choice if space is extremely tight, but the ported
enclosure will produce 3dB more output at the same power if you have the extra space to work with.

!! CAUTION !!
Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance
speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.
When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend
bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers
for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly
important in a hatchback, station wagon, sports utility vehicle, or van.

RECOMMENDED CONTINUOUS RMS POWER RANGE FOR ONE SUBWOOFER DRIVER:
JL Audio offers an extensive line of high-performance subwoofer drivers to fit a wide variety of enclosure and power applications. When designing systems with our drivers, it is very important to achieve a
good power match between the subwoofer amplifier and the subwoofer driver's capabilities. The power levels listed in the above chart represent continuous (RMS) amplifier power per woofer and assume
that the user will regularly make full use of that power without drastically overdriving the amplifier(s). Make sure you factor system impedance and the total number of subwoofers into your calculations.
Adhering to these power recommendations will result in systems that are both reliable and enjoyable.

JL AUDIO LIMITED WARRANTY USA
Automotive Subwoofer Components
MEDIUM GRAY MINIMUM:
From a reliability standpoint, this zone represents
a very comfortable operating power range for
each driver. This level of power will not stress the
woofer but will not extract all of its performance
potential, either.
Use of less than the minimum power level will
not damage the woofer, but may result in
unsatisfactory performance.
LIGHT GRAY OPTIMUM:
This zone represents the best compromise
between long-term reliability, high-output and
low-distortion performance. This power level is
lower than the woofer’s continuous power rating
(as published in its specifications), but you will still
be taking advantage of the woofer’s, low-distortion
performance range without undue risk of failure.
DARK GRAY MAXIMUM:
Slightly more SPL will be gained by pushing
the power into this zone, but typically not more
than 2dB, compared to the light gray zone. The
subwoofer driver is designed to operate safely
up to this power range, but not beyond. Operate
with caution.
BLACK WARRANTY VOID:
We do not recommend operating woofers at this
level of power. In this zone, there is a very high
probability that the driver will fail due to excessive
heat and/or mechanical stress.
Subwoofer drivers operated at these levels of
power are NOT covered under warranty.
