Flush Mount Series Speaker and
Subwoofer Installation Instructions
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the
product box for product warnings and other important
information.
If you intend to mount the speakers outside the boat, you must
mount them in a location well above the waterline, where they
are not submerged or damaged by docks, pilings, or other
pieces of equipment. When mounted correctly, these speakers
are rated for protection from the front of the speaker. Water
exposure and damage to the rear of the speaker voids the
warranty.
You must turn off the audio system before making any
connections to the stereo, amplifier, or speakers. Failure to do
so could result in permanent damage to the audio system.
You should protect all terminals and connections from grounding
and from each other. Failure to do so could result in permanent
damage to the audio system and void the product warranty.
WARNING
This device must be installed according to these instructions.
Disconnect the vehicle's or vessel's power supply before
beginning to install this device.
CAUTION
Continuous exposure to sound pressure levels over 100 dBA
may cause permanent hearing loss. The volume is typically too
loud if you cannot hear people speaking around you. Limit the
amount of time you listen at high volume. If you experience
ringing in your ears or muffled speech, stop listening and have
your hearing checked.
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite
side of the surface.
It is strongly recommended that you have your audio system
installed by a professional installer to ensure optimum
performance.
You must read all installation instructions before beginning the
installation. If you experience difficulty during the installation, go
to www.fusionentertainment.com for product support.
After installing the subwoofer, you should run the subwoofer at
low to medium volumes for the first few hours of use. This helps
to improve the overall sound by gradually loosening up the
moving components of the subwoofer, such as the cone, spider,
and surround
Tools Needed
• Phillips screwdriver
• Torque screwdriver with a Phillips bit
• Appropriate saw or utility knife to cut surface material
• 18 AWG (0.82 mm2) speaker wire
• Marine sealant such as 3M™ 4200 or 5200
• Speaker spade connectors (recommended)
• Wire strippers (optional)
• Crimping tool (optional)
• Electrical tape (optional)
NOTE: For customized installations, additional tools and
materials may be needed.
When selecting a mounting location for the speakers, observe
these considerations:
• You must select mounting locations that provide sufficient
clearance for the mounting depth of the speakers as
specified in the product specifications.
• You must select a mounting location where the panel
thickness is not thinner or thicker than specified in the
product specifications.
• You should select a flat mounting surface for the best seal.
• You should protect the speaker wires from sharp objects and
always use rubber grommets when wiring through panels.
• To avoid interference with a magnetic compass, you should
not mount the speakers closer to a compass than the
compass-safe distance value listed in the product
specifications.
Selecting the correct mounting location optimizes the
performance of each speaker. FUSION® speakers are designed
to perform in the widest possible range of mounting locations,
but the more you plan the installation, the better the speakers
will sound. For more information on speaker placement and
specifications, go to www.fusionentertainment.com.
Mounting the Speakers
Use the included template with a rotary tool or jigsaw to cut
1
the hole for the speaker.
Connect the speaker wires while observing polarity (Speaker
2
Wiring, page 2).
Apply marine sealant on the speaker and the mounting
3
surface.
Place the speaker in the cutout.
4
Using a #2 Phillips screwdriver, turn the screws to extend
5
the mounting tabs lightly hold the speaker to mounting
surface.
Mounting Considerations
NOTICE
When mounting the speaker in an area exposed to weather or
water, you must mount the speaker on a vertical surface. If you
mount the speaker on a horizontal surface facing up, water can
gather in and around the speaker, causing damage over time.
NOTICE
Although you may use a power screwdriver to initially turn the
screws on the mounting tabs, you must use a torque
screwdriver to complete the installation. Using power tools to

fully tighten the screws can damage the speaker housing and
make it difficult to install the speaker grille.
Using a torque screwdriver, tighten the screws by hand to
6
1.0 Nm (0.74 lbf-ft) on the FM-F65/F77 speaker models or
1.5 Nm (1.11 lbf-ft) on the FM-S10 subwoofer models.
With the speaker mounted, place the grille onto the speaker,
7
and push to secure it.
Speaker Wiring
When connecting the speakers or subwoofer to your stereo or
amplifier, observe these considerations.
• Speaker wire is not included with the speakers or subwoofer.
You should use 18 AWG (0.82 mm2) speaker wire to connect
the speakers or subwoofer to the stereo or amplifier.
• The leads on the speakers and subwoofer are terminated
using male spade connectors. You should use female spade
connectors (not included) to connect the speaker wire to the
leads for the best connection.
• The subwoofer features a dual 2 Ohm voice coil that can be
configured for 2.1 operation (two speakers and one
subwoofer) when connected to a compatible FUSION stereo
(Configuring the Subwoofer for 2.1 Operation, page 2).
You can use these tables to identify the polarity and spadeconnector sizes of the leads on the speakers or subwoofer.

Cleaning the Speakers
NOTE: When mounted correctly, these speakers are rated IP65
for dust and water ingress protection under normal conditions.
They are not designed to withstand high pressure water spray,
which may occur when you wash down your vessel. Failure to
carefully spray-clean the vessel may damage the product and
void the warranty.
NOTICE
Do not use harsh or solvent-based cleaners on the speakers.
Using such cleaners may damage the product and void the
warranty.
Clean all salt water and salt residue from the speaker with a
1
damp cloth soaked in fresh water.
Use a mild detergent to remove a heavy buildup of salt or
2
stains.
Gray and white with a black stripe wires are connected to
jumper terminals on the back of the subwoofer. These wires
must remain connected to the jumper terminals for normal use
(4 Ohm) and should be disconnected only when configuring the
subwoofer for 2.1 operation.
Configuring the Subwoofer for 2.1 Operation
The subwoofer features dual 2 Ohm voice coils and is preconfigured for 4 Ohm operation. You can change the
configuration of the subwoofer for 2.1 operation (two speakers
and one subwoofer) when connected to a FUSION 2 Ohmstable stereo with DSP capability, such as an Apollo™ RA770.
See www.fusionentertainment.com for more information about
compatible stereos.
Disconnect the gray wire and the white with a black stripe
1
wire from the jumper terminals on the back of the subwoofer.
Connect the wires from the subwoofer to the stereo using the
2
following table as a reference.
Subwoofer lead Stereo connection
White Zone 2 right positive (+)
White with a black stripe Zone 2 right negative (-)
Gray Zone 2 left positive (+)
Gray with a black stripe Zone 2 left negative (-)
Turn on the connected stereo.

Launch the FUSION-Link™ app, and select the 2.1 option for
4
the connected stereo.
The subwoofer operates in 2.1 mode, with the volume control
tied to zone 1 on the stereo. The zone 2 volume control and the
zone 2 line out connectors are disabled.
