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
).
1 Route the appropriate gauge of wire to the amplifier and to a ground location on the boat.
2 Using the included 3 mm hex key, connect the ground wire to the GND terminal on the amplifier.
3 Connect the other end of the ground wire to the ground location on the boat.
4 Route 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.
5 Select an option:
• If your stereo has an amplifier turn-on wire, route a 20 AWG (0.52 mm
2
) 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 mm
2
) wire from the positive
terminal of the battery, through a switch, to the amplifier.
6 Using the included 2.5 mm hex key, connect the 20 AWG (0.52 mm
2
) 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 11
).
