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.
This device must be installed according to these instructions.
Disconnect the power supply to the vessel's audio system before beginning to install this device.
CAUTION
Continuous exposure to sound pressure levels over 100dBA 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.
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
NOTICE
YOU MUST NOT USE THIS AMPLIFIER WITH ANY THIRD-PARTY MARINE AUDIO SYSTEMS. This amplifier
is compatible only with Fusion DSP-enabled marine audio equipment and may cause damage to third-party
speakers due to the amplifier power output.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
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 support.garmin.com for product support.
After installing an audio system, you should run the connected speakers and subwoofers at low to medium
volumes during their first few hours of use. This helps to improve the overall sound by gradually loosening
up the moving components in the new speakers and subwoofers, such as the cone, spider, and surround.
See the installation instructions provided with your speakers, because there may be more details about the
recommended low-to-medium volume usage time for each model.
NOTE: After installing the amplifier, you must set up your connected stereo using the Fusion-Link™ app to select
and activate the correct DSP profile.

Mounting Considerations
CAUTION
In high ambient temperatures and after extended use, the device enclosure may reach temperatures deemed
dangerous to touch. To avoid possible personal injury, the device must be installed in a location where it will not
be touched during operation.
NOTICE
This device should be mounted in a well-ventilated location that is not exposed to extreme temperatures or
conditions. The temperature range for this device is listed in the product specifications. Extended exposure to
temperatures exceeding the specified temperature range, in storage or operating conditions, may cause device
failure. Extreme-temperature-induced damage and related consequences are not covered by the warranty.
This device is designed for installation only in a dry location. Installing this device in a location where it may
come in contact with more than occasional dripping water or become submerged may result in damage. Water
damage is not covered by the warranty.
You must not mount this device upside-down on the underside of a horizontal mounting surface. Mounting the
device in an upside-down orientation reduces the effectiveness of heat dissipation, and may lead to shutdown
due to thermal protection.
If you are mounting the device on fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
You can mount this amplifier using one of two methods:
• You can use the included bracket and pan head screws to mount the amplifier (Installing the Mounting
Bracket, page4).
◦Mounting the amplifier using the bracket allows you to quickly attach and detach the amplifier from the
mounting surface.
◦Mounting the amplifier using the bracket requires clear space above the mounting location to allow for
connecting the amplifier to the bracket and installing the locking wedge.
• You can use the included flat-head, countersunk screws to mount the amplifier directly to the mounting
surface (Mounting the Device Directly to the Surface, page7).
◦Mounting the amplifier directly to the surface does not allow you to quickly detach the amplifier.
◦Mounting the amplifier directly to the surface does not require as much clear space above the mounting
location, so it may be a more suitable choice for installing in a smaller space.
When selecting a mounting location, observe these considerations:
• You must mount the amplifier in a location that does not interfere with the fuel tank or electrical wiring.
• You must mount the amplifier in a location where it is not exposed to water.
• You must mount the amplifier in a location where it is not exposed to fuel or fuel vapor.
• You must mount the amplifier in a location with adequate ventilation where it is not exposed to extreme
temperatures.
• If you mount amplifier in an enclosed space, you should install a cooling fan with appropriate ducts to aid in
airflow.
• You should mount the amplifier so that the cables can be connected easily.
• You must not mount the amplifier upside-down on the underside of a horizontal mounting surface.
• To avoid interference with a magnetic compass, you should mount the amplifier the specified distance away
from a compass. This distance is listed in the specifications section.
• You must not mount the amplifier in close proximity to other navigation-critical equipment, antennas, or
radio-communication equipment on the vessel.

Installing the Mounting Bracket
NOTICE
Pan-head screws are included, but they may not be suitable for the mounting surface. If you provide different
mounting hardware, you must not use fasteners with a countersunk head. Hardware with a countersunk head
will damage the mounting bracket.
Before you install the mounting bracket, you must select a mounting location and determine what screws and
other mounting hardware are needed for the surface.
Mounting the device using the mounting bracket allows you to quickly attach and remove the device as needed.
1Use the included template to verify that the mounting location has sufficient clearance to install the device.
NOTE: You must install the bracket with the release tab pointing up to properly secure the amplifier in the
bracket.
2Using a 3mm (1/8in.) bit or a bit appropriate for your provided hardware and mounting-surface material, drill
the pilot holes marked on the template.
NOTICE
If you are mounting the device on fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
3Using the included pan-head screws or other pan-head mounting hardware, secure the bracket to the
mounting surface.
NOTICE
You must use pan-head screws, because countersunk screws will damage the bracket.
4
Connecting the Device to the Mounting Bracket
You must secure the mounting bracket to the surface before you can connect the device.
1Hold the device over and slightly above the mounting bracket.
2Place the device onto the bracket and pull down until the tab audibly clicks.
3Insert the wedge over the tab on the top of the mounting bracket it and push down to lock the device in the
bracket.
4Install the included screw covers in the four holes on the top of the amplifier (optional).
5
Removing the Device from the Mounting Bracket
1Lift up to remove the wedge, which unlocks the tab on the mounting bracket.
2Press the tab on the mounting bracket, and lift up on the amplifier to disconnect it from the mount .
6
Mounting the Device Directly to the Surface
If you are installing the device in a location with limited space, or you do not want to use the bracket, you can
mount the device directly to the surface.
NOTE: Countersunk screws are provided to mount the device directly to the surface. If you choose to use your
own hardware to mount the device directly to the surface, countersunk heads are recommended.
1Using the provided template, mark the pilot hole locations for the four mounting holes on the device,
observing these considerations:
• Because you are not using the bracket, you do not need to observe the upper clearance line on the
template.
• You must observe the lower clearance line on the template so that you have the space needed to make
the cable connections.
2Using a 3mm (1/8in.) bit or a bit appropriate for your provided hardware and mounting-surface material, drill
the pilot holes.
NOTICE
If you are mounting the device on fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
3Using the provided countersunk screws, secure the device to the mounting surface.
4Install the included screw covers in the four holes on the top of the amplifier (optional).
Connection Considerations
NOTICE
You should disconnect the power supply to the audio system before making any connections to the amplifier.
Failure to disconnect the audio system may result in damage to the amplifier or audio system.
All terminals and connections must be protected from contact with other conductive materials, such as the
vessel chassis and other wires. Improper terminal or wire contact may result in damage to the audio system.
When routing power, speaker, and RCA cables, make sure they are not pinched or crushed. A pinched cable may
result in contact with other conductive materials which may damage the audio system.
NOTE: You must connect the amplifier to the AMPLIFIER ON wire from the stereo for the amplifier to turn on
and off with the stereo.
When selecting and routing cables, consider the following:
• You should use RCA signal cables that are of the appropriate length to connect the stereo to the amplifier.
Avoid using cables that are much longer than needed.
• When routing cables, you should not route RCA cables alongside the power cables. Routing audio cables next
to the power cables may introduce interference or unwanted noise in the audio signal.
• When routing cables, protect them from sharp objects. You should use rubber grommets when routing cables
through metal panels to protect the cables.

Connecting to Power
WARNING
The positive wire (not included) from the power source to the amplifier must run through a 40A inline fuse
or circuit breaker (not included) as close to the power source as possible. Connecting the amplifier to power
without an inline fuse or circuit breaker may result in a fire if there is a short in the cable.
You should use 4AWG (21 through 25 mm2) marine-grade, fully-tinned copper wire (not included) to connect the
amplifier to power and ground for most installations. For power-cable runs longer than 5m (16ft.), you should
consider using larger-diameter (smaller gauge number) wire to minimize power loss.
You must connect the REM terminal on the amplifier block to either the AMPLIFIER ON wire from the connected
stereo or to a constant 12Vdc power source using a switch.
NOTICE
Connecting to the AMPLIFIER ON wire from the stereo instead of using an external switch is recommended to
avoid damaging your speakers when the stereo turns on or off.
1Route 4AWG (21 through 25 mm2) marine-grade, fully-tinned copper ground wire (not included) to the
amplifier and to a ground location on the boat.
2Using a 5mm (7/32in.) flat (slotted) screwdriver, connect the ground
wire to the GND terminal on the power connection block.
3Connect the other end of the ground wire to the ground location.
4Route 4AWG (21 through 25 mm2) marine-grade, fully-tinned copper
power wire (not included) to the amplifier and to the power source.

5As close to the power source as possible, install a 40A inline fuse on the power wire in an accessible
location or connect the power wire through a 40A circuit breaker.
WARNING
Connecting the amplifier to power without a 40A inline fuse or circuit breaker may result in a fire if there is a
short in the cable.
6Using a 5mm (7/32in.) flat (slotted) screwdriver, connect the power (+) wire to the PWR terminal on the
power connection block.
7Route a 20AWG (0.5 through 0.75mm2) marine-grade, fully-tinned copper remote-on wire (not included)
from the amplifier to the AMPLIFIER ON wire on the stereo.
NOTE: The amplifier and the stereo must connect to a common ground terminal point for the AMPLIFIER ON
signal to function properly.
8Using a 4mm (5/32in.) flat (slotted) screwdriver, connect the remote-on wire to the REM terminal on the
power connection block.
NOTICE
You should wait to connect the power terminal block to the amplifier. Make all of the other connections to the
stereo and speakers before completing the connection to power (Completing the Connections, page11).
Signal and Speaker Connection Considerations
When connecting your stereo and subwoofer to the amplifier, observe the following considerations:
• A subwoofer connects to the amplifier using a terminal block (Connecting a Subwoofer to the Amplifier,
page10).
• The amplifier supports a nominal 4Ohm speaker load impedance, and a 2Ohm minimum speaker load
impedance.
• When connecting a subwoofer, you should use 12 AWG (3 through 4mm2) marine-grade, fully-tinned copper
wire.
• You must connect a 1-channel RCA cable from the subwoofer line out port on the stereo to the single-RCA
input port on the amplifier.
9
Connecting a Subwoofer to the Amplifier
1Route12 AWG (3 through 4mm2) marine-grade, fully-tinned copper wire to the subwoofer and the amplifier.
NOTE: You should label both ends of the speaker wire, including polarity, so you can easily identify which
wires route to which subwoofer.
2Connect the speaker wire to the subwoofer, observing polarity.
NOTE: Incorrectly connecting the speaker wire by crossing the polarity may result in poor sound quality.
3Using a 4mm (5/32in.) flat (slotted) screwdriver, connect the speaker wires to the speaker terminal block.
NOTE: The speaker terminal block is not labeled. Refer to the label on the amplifier port when determining
polarity.
4When both speaker wires are connected to the terminal block, press the assembled terminal block into the
port on the amplifier to complete the subwoofer connection.
5Connect a 1-channel RCA cable to the RCA subwoofer line-out connector from the stereo for a zone you want
to use with the subwoofer.
