INSTALLATION PROCEDURE
The diagram above shows the typical installation procedure into a fiberglass
panel using the supplied hardware (Classic Grille Model shown. Installation
is the same for Sport Grille Models). Always follow proper safety procedures
when working on a vessel. Use eye-protection at all times and a dust mask and
gloves when cutting.
1) Choose a flat mounting surface that has sufficient
depth and air space behind
it to accept the subwoofer.
2) Cut a 7.375-inch (187 mm) diameter hole.
3) Run the speaker cable to the mounting location.
4) Place the woofer in the hole and mark the screw hole locations using a sharp,
pointed tool.
5) Remove the woofer and drill a pilot hole
(see chart on next page) in each of the screw locations. It is also advisable to use
a hand-driven countersink tool on each hole to further inhibit
gel-coat cracking of fiberglass panels.
6) Connect the speaker wires and place the woofer, with its grille in place, into the
opening (for Sport Grille models, pay attention to where the logo badge will added.
7) While holding the speaker firmly in its mounting location, evenly snug the
mounting screws in a criss-cross pattern, then hand tighten in a criss-cross pattern.
Non-standard installations may require different hardware. Always use
marine-grade, stainless-steel fasteners to ensure a secure, reliable installation.

** Efficiency (1W/1m) is an accurate indicator of a subwoofer’s output capability not
and should not be used as a comparison to other subwoofers to determine which
one is “louder” !
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.

INTERCHANGEABLE LOGO BADGE
(Sport-Grille Models Only)
Interchangeable Logo Badges for Sport Grille
model subwoofers are included to further customize
your installation. The design of the Sport Grille allows
for the JL Audio logo to be added in your choice of
included colors and oriented in the manner that best
suits your installation.
NOTE: A left and a right badge of each color is
included. These two different orientations ensure the
“JL Audio” Logo will read correctly wherever positioned
(most commonly the 3:00 or 9:00 position).
Remove the adhesive backing from the badge
and affix the badge to the grille using the small
positioning hole as a guide. See diagram at right.
! ! CAUTION ! !
While this speaker is designed to be water and
spray resistant, it is not designed to be submerged
or to withstand high-pressure water spray.
Please exercise care when washing your boat to
avoid damaging your speaker. Do not install on
submersibles, personal watercraft or any other
vessel likely to be under water at any time.
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 vessel, it is
extremely important to secure it firmly. This applies
not only to the woofer itself, but also the structure
it is mounted to. If not firmly attached, the speaker
can become a dangerous projectile in a collision.
Please review the mounting information carefully
and use the supplied marine-grade hardware to
mount this product.

NOTE: 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.
NOTE: 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.
