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.
• 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,
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.
