Mounting the SG-DA61500/SG-24DA61500 Signature Series Device
NOTICE
If you are mounting the device in 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.
NOTE: Screws are included with the device, but they may not be suitable for the mounting surface.
Before you mount the device, you must select a mounting location and determine what screws and other
mounting hardware are needed for the surface.
1Place the device in the mounting location and mark the location of the pilot holes.
2Drill a pilot hole for one corner of the device.
3Loosely fasten the device to the mounting surface with one corner and examine the other three pilot-hole
marks.
4Mark new pilot-hole locations if necessary, and remove the device from the mounting surface.
5Drill the remaining pilot holes.
6Secure the device to the mounting location.
Removing the Cover
You must remove the cover to reach the connectors and configuration controls on the amplifier.
1Using the included 3mm hex key, remove the screws that secure the cover to the amplifier.
2Lift the cover off of the amplifier and set it aside until after you have finished making all of the connections
and configured the amplifier.
Connection Considerations
NOTICE
The wiring (not included) from the battery to the amplifier must run through an inline fuse or circuit breaker (not
included) as close to the battery as possible. You must connect the positive wire to the fuse or circuit breaker.
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 must turn off the audio system before making any connections to the amplifier. Failure to turn off the audio
system may result in damage to the audio system.
All terminals and connections must be protected from contact with the vessel chassis and with each other.
Improper terminal or wire contact may result in damage to the audio system.
• You must first connect the amplifier to ground before making any other wiring connections (Connecting to
Power, page5).
• You must connect the positive wire to the battery only after you have completed all other wiring to the
amplifier.
• If your stereo does not have a remote turn-on signal wire, you must connect the amplifier to a switched power
source.

Connecting to Power
You must connect the power wire to the battery through an in-line fuse or a circuit breaker.
You must use the appropriate gauge of wire (not included) to connect the amplifier to power and ground, based
on the total amperage and the length of the cable run (Power Cable Gauge Guide, page6).
1Route the appropriate gauge of wire to the amplifier and to a ground location on the boat.
2Using the included 3mm hex key, connect the ground wire to the GND terminal on the amplifier.
3Connect the other end of the ground wire to the ground location on the boat.
4Route the appropriate gauge of wire to the amplifier and to the boat battery, and select an option:
• Install a properly rated in-line fuse on the power wire as close to the battery as possible.
• Identify or install a circuit breaker, as close to the battery as possible, for use with the amplifier power
wire.
NOTICE
You must not connect the power wire to the amplifier and battery or circuit breaker before you complete all of
the other connections. Connecting the amplifier to power before you complete all of the other connections may
cause damage to your audio system.
5Select an option:
• If your stereo has an amplifier turn-on wire, route a 20AWG (0.52mm2) wire from the amplifier turn-on
wire on the stereo to the amplifier.
NOTE: The amplifier and the stereo must connect to the same physical ground location for the amplifier
turn-on signal to function properly.
• If your stereo does not have an amplifier turn-on wire, route a 20AWG (0.52mm2) wire from the positive
terminal of the battery, through a switch, to the amplifier.
6Using the included 2.5mm hex key, connect the 20AWG (0.52mm2) wire to the REM terminal on the
amplifier.
Make all of the other connections to the stereo and speakers before completing the connection to power
(Completing the Connections, page11).

Power Cable Gauge Guide
You should use 4AWG (21.1mm2) wire for most installations. If your total amperage is higher than 50–65A,
and your cable run is longer than 10–13ft (3–4m), you can use these tables to determine if you need to use a
larger gauge of wire. This table accounts for terminal connection resistance.
NOTE: If you are using aluminum wire, you should use a wire two gauges larger than the gauge listed below to
compensate for a potential voltage drop due to the wire material.

Signal and Speaker Connection Considerations
When connecting your stereo and speakers to the amplifier, observe the following considerations:
• Each set of zone speaker terminals on the amplifier is paired to the RCA inputs for that zone.
• Each channel supports a nominal 4Ohm speaker load impedance, and a 2Ohm minimum speaker load
impedance.
• You can connect two speakers in parallel on a single channel, and the combined impedance must be
greater than the 2Ohm minimum load impedance (Connecting Multiple Speakers or Subwoofers In Parallel,
page9).
• You can connect either a zone line out or a subwoofer line out from the stereo to any of the zone RCA inputs
on the amplifier.
• You should use the proper gauge speaker wire noted in the Speaker Wire Gauge Guide, page8 to connect
speakers and subwoofers to the amplifier.
• You should observe the zone and polarity markings for each channel when connecting speakers to the
amplifier. For example, Z1L indicates the ZONE 1 left channel, and Z1R indicates the ZONE 1 right channel.
• If you are connecting a combination of speakers and a subwoofer to the amplifier, you should connect the
subwoofer to ZONE 3 as illustrated below. This zone has a dedicated BASS BOOST control.
• You can connect a subwoofer to a single channel, but you should connect it using bridge mode to get the
best performance (Connecting a Speaker or Subwoofer in Bridge Mode, page10).
In the following example, a single 4Ohm subwoofer is connected to the bridged terminals for ZONE 3, and pairs
of 4Ohm speakers are connected to the right and left channels for the other two zones.
In this example, you must connect the subwoofer line out from the stereo to the Z3L and Z3R RCA connectors
on the amplifier (using an RCA splitter), you must connect the two zone line out connectors from the stereo to
the other two zone RCA connectors on the amplifier.

Speaker Wire Gauge Guide
You should use 16 AWG (1.3 through 1.5mm2) fully-tinned copper speaker wire for most installations. You
can use these tables to determine if you need to use a larger gauge of wire. These tables account for terminal
connection resistance.
NOTE: If you are using aluminum wire, you should use a wire two gauges larger than the gauge listed below to
compensate for a potential voltage drop due to the wire material.
4 Ohm Load (1 Speaker)
Distance between the amplifier and speaker Wire gauge
From 0 to 28ft. (from 0 to 8.5m) 16 AWG (1.3 through 1.5mm2)
From 28 to 69ft. (from 8.5 to 21m) 12 AWG (3 through 4mm2)
2 Ohm Load (2 Speakers in Parallel)
Distance between the amplifier and speaker Wire gauge
From 0 to 14ft. (from 0 to 4m) 16 AWG (1.3 through 1.5mm2)
From 14 to 35ft. (from 4 to 10.5m) 12 AWG (3 through 4mm2)
You can purchase the recommended speaker wire from your Fusion® or Garmin® dealer.
• 16 AWG (1.3 through 1.5mm2) wire:
◦010-12899-00: 7.62m (25ft.)
◦010-12899-10: 15.24m (50ft.)
◦010-12899-20: 100m (328 ft.)
• 12 AWG (3 through 4mm2) wire:
◦010-12898-00: 7.62m (25ft.)
◦010-12898-10: 15.24m (50ft.)
◦010-12898-20: 100m (328 ft.)

Connecting Multiple Speakers or Subwoofers In Parallel
You can connect multiple speakers or subwoofers with the same impedance rating, model number, and type
together in parallel. When connecting speakers of the same impedance rating in parallel, you must calculate
the total impedance by dividing the common impedance rating by the total number of speakers connected in
parallel. For example, if you connect two 4Ohm speakers in parallel, the resulting impedance is 2Ohm (4÷ 2=
2).
NOTICE
You must not connect a series of speakers with an impedance less than 2Ohm to a single channel on the
amplifier. Do not connect more than two speakers in parallel per zone output.
1Connect speaker wire to the positive terminal for a channel or zone on the amplifier.
2Connect speaker wire to the positive terminal on each speaker.
3Connect the wires from the positive terminals on both speakers in the channel or zone to the wire connected
to the positive terminal on the amplifier.
4Repeat this procedure for the negative terminal on the amplifier and both speakers in the channel or zone.
9
Connecting a Speaker or Subwoofer in Bridge Mode
Connecting a speaker or subwoofer in bridge mode increases the amount of power that can be delivered by
combining two output channels together. This is beneficial for large subwoofers that move large volumes of air
and for playing speakers louder without experiencing clipping in the audio.
NOTICE
A speaker connected in bridge mode must be capable of handling the increased output power. Bridge mode can
produce more than double the output power of a single channel.
You should connect only a 4Ohm load to the bridged terminals on a zone. Connecting a 2Ohm load to the
bridged terminals may cause damage to the amplifier, speaker, or subwoofer.
NOTE: When bridging the channels in a zone, you must use an RCA splitter to send the same signal to both the
left and right channels of the zone.
1Connect speaker wire to the amplifier's positive terminal of the left channel for a zone .
2Connect the other end of the speaker wire to the positive terminal on the speaker or subwoofer .
NOTE: The bridged terminals for a zone are connected with a line and labeled BRIDGED for easy
identification.
3Connect speaker wire to the negative terminal of the right channel for a zone .
4Connect the other end of the speaker wire to the negative terminal on the speaker or subwoofer .
5Connect the split ends of an RCA splitter to the left RCA ports for both bridged zones on the amplifier .
6Connect the single end of the RCA splitter to the left RCA stereo output .
7Connect the split ends of an RCA splitter to the right RCA ports for both bridged zones on the amplifier .
8Connect the single end of the RCA splitter to the right RCA stereo output .
9Adjust the volume level and other settings for the zone (Adjusting the Level for a Zone, page13).
