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 vehicle's or vessel's power supply before beginning to install this device.
CAUTION
To maintain ignition protection compliance in accordance with SAE J1171, you must replace the fuse only with
a J1171 compliant fuse.
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.
To avoid possible personal injury, 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 to avoid damaging the vessel.
This device is designed for a 12 Vdc power source. Connecting to a 24 Vdc or larger power source may damage
the device.
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
garmin.com
for product support.

Page 2: Tools Needed
Tools Needed • Drill and drill bits • Flat screwdriver • Wire cutter • Wire stripper • 160 A inline fuse or circuit breaker for the power cable • 4 AWG (21.1 mm ) power cable NOTE: You may need thicker cable for higher amperages or longer runs (Power Cable Gauge Guide, page 6). -
Page 3: Removing The Cover
Mounting the SG-DA82000 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. -

Page 5: Connecting To Power
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, page 6). - Page 6 Power Cable Gauge Guide You should use 4 AWG (21.1 mm ) wire for most installations. If your total amperage is higher than 50–65 A, and your cable run is longer than 10–13 ft (3–4 m), you can use these tables to determine if you need to use a larger gauge of wire.

Page 7: Signal And Speaker Connection Considerations
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 4 Ohm speaker load impedance, and a 2 Ohm minimum speaker load impedance. - Page 8 16 AWG (1.3 through 1.5 mm From 14 to 35 ft. (from 4 to 10.5 m) 12 AWG (3 through 4 mm You can purchase the recommended speaker wire from your Fusion ® or Garmin ® dealer. • 16 AWG (1.3 through 1.5 mm ) wire: ◦...
- Page 9 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.
- Page 10 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.

Page 11: Completing The Connections
Completing the Connections Before you connect the amplifier to the power source, you must complete all other connections to the amplifier . 1 Make sure all speaker wires are connected to the speakers and the amplifier. 2 Make sure all RCA cables are connected to the amplifier and the stereo. 3 Make sure the ground cable is connected to the amplifier and the battery (Connecting to Power, page 5). -
Page 12: Amplifier Configuration Controls
Amplifier Configuration Controls Each zone has a set of controls you must use to configure the sound for the speakers connected to that zone. Dial or Function Switch LEVEL Adjusts the input signal level for the zone (Adjusting the Level for a Zone, page 13). -
Page 13: Adjusting The Level For A Zone
Adjusting the Level for a Zone NOTE: The level setting is music dependent, and not all levels are appropriate for all types of music. For example, if you adjust the level setting for rock music, then listen to classical music, it could result in distortion due to clipping. -
