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.

• The enclosure recommendations listed 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 are net internal volumes!
Box volume displacement, port displacement and
brace displacement must be added to obtain the final
gross internal volume. All enclosure dimensions listed
have already taken this into account.
• When using two subwoofers in a common
enclosure simply double the required volume and,

13W3v3-4: 17.75 in. (451 mm)
13W3v3-8: 18.125 in. (460 mm)
in the case of a ported enclosure, use two times the
recommended port(s).
• We recommend the use of this speaker in a bi-
amplified system using high-quality satellite speakers
and amplifiers. 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
CAUTION
in a hatchback, station wagon, sports utility vehicle, or van.

RECOMMENDED CONTINUOUS (RMS) POWER RANGE FOR ONE SUBWOOFER DRIVER:

LEGEND:
MINIMUM
OPTIMUM MAXIMUM
WARRANTY VOID
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.
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.
LIGHT GRAY (OPTIMUM):
This zone represents the best compromise
between long-ter m reliabilit y, high- outpu t and
low-d istor tion perfor mance . This power level i s
lower than the woofer’s continuous power rating
(as pu blished in its s pecif icati ons) , but you w ill still
be tak ing adv antage of the woofer’s, low-dis tortion
perf orman ce range witho ut 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.
