Series Amplifier 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.

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.

The SG-DA61500 device is designed for a 12 Vdc power source. The SG-24DA61500 device is designed for a 24 Vdc power source. Connecting to a 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 www.fusionentertainment.com for product support.

Mounting Considerations

CAUTION

In high ambient temperatures and after extended use, the device enclosure may reach temperatures deemed dangerous to touch. Therefore the device must be installed in a location where it will not be touched during operation.

NOTICE

This device should be mounted in a 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 water or become submerged may result in damage. Water damage is not covered by the warranty.

•The device must be mounted in a location that does not interfere with the fuel tank or electrical wiring.

•The device must be mounted in a location where it is not exposed to water.

•The device must be mounted in a location with adequate ventilation where it is not exposed to extreme temperatures.

•If the device is mounted in an enclosed space, you should install a cooling fan with appropriate ducts to aid in airflow.

•The device should be mounted so that the cables can be connected easily.

•To avoid interference with a magnetic compass, the device should be installed at least 55 cm (22 in.) away from a compass.

•The device should not be mounted in close proximity to other navigation-critical equipment, antennas, or radiocommunication equipment on the vessel.

Mounting the SG-DA61500/SG-24DA61500 Signature

Series Device

NOTICE

If you are mounting the device in fiberglass, when drilling the pilot holes, it is recommended to 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.

2 Drill 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.

5 Drill the remaining pilot holes.

6 Secure 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 3 mm 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,

page 2).

•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 inline 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 2).

1Route the appropriate gauge of wire to the amplifier and to a ground location on the boat.

2Using the included 3 mm 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

20 AWG (0.52 mm2) 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 20 AWG (0.52 mm2) wire from the positive terminal of the battery, through a switch, to the amplifier.

6Using the included 2.5 mm hex key, connect the 20 AWG (0.52 mm2) 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, page 4).

Power Cable Gauge Guide

You should use 4 AWG (21.1 mm2) 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. 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.

Total Amperage	0––4 ft.	4–7 ft.	7–10 ft.	10–13 ft.
	(0–1.2 m)	(1.2–2.1 m)	(2.1–3 m)	(3–4 m)
