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.
