* 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” !
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.
INCLUDED PARTS

• Six #10 x 1 5/8-inch (41 mm) pan-head
stainless-steel screws
• Six #10 stainless-steel washers
• Logo Badges (Sport-Grille Models Only)
One Pair Black (White & Titanium/Black Models)

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 8.875-inch (225 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.

#10 SCREW: PILOT HOLE RECOMMENDATIONS
!!
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.

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.

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.

RECOMMENDED CONTINUOUS RMS POWER RANGE FOR ONE SUBWOOFER DRIVER:
MEDIU M GRAY MINI MUM:
From a r eliabil ity sta ndpoint , th is z one
represe nts a very comfor table operating power
range f or each dri ver. This level of power wi ll not
stress th e w oofer but will not e xtract all of its
perfo rmance potenti al, either.
Use of l ess tha n the minimu m power level
will not dam age the woofer, but may re sult in
unsatis factory pe rformance.
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 OPTIMU M:
This zone rep resents the best compromise
between long-term reliability, high-output and
low-distortion performance. This power level is
lower than the woofer’s continuous power rating
(as published in its s pecificat ions), bu t you will still
be taking advantage of the woofer’s, low-distortion
performance range without undue risk of failure.
DARK G RAY 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 subwo ofer
driver is designed to operate safely up to this power
range, but not beyond. Operate with caution.
BLACK WA RRANTY VOID:
We do not recomme nd operating woofe rs at
this level of power. In this z one, there is a ver y
high proba bility that the driv er will fail due to
excessive heat and/or mec hanical stres s.
Subwoofer drivers operated at these levels of
power are NOT covered under warranty.
