* 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.
All specifications are subject to change without notice.

!! CAUTION !!
INSTALLATION PROCEDURE
This diagram shows the typical installation
procedure into a fiberglass panel using the supplied
hardware. 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 M10IB5.
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 below) in each of the screw locations.
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.
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.
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
Included Parts:
• One Polymer Subwoofer Grille
• Six #10 x 1 5/8-inch (41 mm) hex-head stainless-
steel screws (require 5/32-inch hex wrench)
• Six #10 stainless-steel washers
• One 5/32-inch (3.97 mm) hex wrench

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.
LIGHT GRAY (OPTIMUM):
This zone represents the best compromise
between long-term reliability, high-output and low-
distortion performance and is centered on each
woofer's continuous power rating (as published in
its specifications). In this zone, you will be taking full
advantage of the woofer's optimum, low-distortion
performance range without undue risk of failure.
DARK GRAY (MAXIMUM):
In this zone, low-distortion output and long-term
reliability will be compromised (especially by an
aggressive user). 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 closer you are to the black zone, the higher the
likelihood of driver failure. 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.
JLM10IB5-4-03012005
JL AUDIO warrants this speaker to be free of defects in materials and
workmanship for a period of one (1) year from the original date of purchase,
contingent upon installation being performed or approved by an authorized
JL AUDIO dealer, in writing, on the original sales receipt. If the preceding
condition is not met, the warranty term is limited to ninety (90) days
from the original purchase date.

misuse, abuse, product modification or neglect, failure to follow installation
instructions, unauthorized repair attempts, misrepresentations by the seller.
This warranty does not cover incidental or consequential damages and does not
cover the cost of removing or reinstalling the unit(s). Cosmetic damage due to
accident or normal wear and tear is not covered under warranty.
This warranty is not transferable and applies only to the original
purchaser of the product from an authorized JL AUDIO dealer.
Warranty is voided if the factory-applied product serial number is
removed or defaced.
Should service be necessary under this warranty for any reason due to
manufacturing defect or malfunction, JL AUDIO will, at its discretion, repair or replace
the defective product with new or remanufactured product at no charge.
Any applicable implied warranties are limited in duration to the period of the
express warranty as provided herein beginning with the date of the original purchase

authorized dealers will be refused unless specifically authorized by JL AUDIO with
a valid return authorization number. Warranty expiration on products returned
without proof of purchase will be determined from the manufacturing date code.
Coverage may be invalidated as this date is previous to purchase date. Return
only defective components. Non-defective items received will be returned freight-
collect. Customer is responsible for shipping charges and insurance in sending the
product to JL AUDIO. Freight damage on returns is not covered under warranty.
Always include proof of purchase (sales receipt).
RECOMMENDED CONTINUOUS (RMS) POWER RANGE FOR ONE SUBWOOFER DRIVER:
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.
