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.

JL AUDIO 6W3v3-4/6W3v3-8 3

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
thanthewoofer’scontinuouspowerrating
(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.
