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.
If you decide to build one of these enclosures yourself, you must have the construction of the box
inspected and approved by your authorized JL Audio dealer in order for the 1 year limited warranty to
be valid. Please read the warranty information carefully.

*Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied. **Efficiency (1W/1m) is not an accurate indicator of
a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”. ***Re (DC resistance) is measured with
the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications remain the same.

• The enclosure recommendations listed above are
external dimensions which assume the use of 3/4"
(19mm) thick material. If you are using 5/8"
(16mm) thick material, subtract 1/4" (6.5mm) from
each dimension. Do not use any material with a
thickness of less than 5/8" (16mm) as this may
compromise the rigidity of the enclosure.
• All enclosure volumes listed above are net
internal volumes! Driver displacement, port
displacement and brace displacement must be
added to obtain the final gross internal volume.
All enclosure dimensions above have already taken
this into acount.
• When using two subwoofers in a common
enclosure simply double the required volume and,
in the case of a ported enclosure, use two times
the recommended port(s). Likewise, when using
three subwoofers in a common enclosure simply
triple the required volume and, in the case of a
ported enclosure, use three times the
recommended port(s).
• We recommend the use of this speaker in a
bi-amplified system using high-quality satellite
speakers and a high-quality amplifier. We do not
recommend the use of this subwoofer with a
passive crossover (coil), as this type of device will
adversely affect performance.

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.
CAUTION
All specifications are subject to change without notice.
