5 Using a 5 mm (
7
/
32
in.) flat (slotted) screwdriver, connect the power (+) wire to the PWR terminal on the
power connection block.
6 Route a 20 AWG (0.5 through 0.75 mm
2
) 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 location for the AMPLIFIER ON
signal to function properly.
7 Using a 4 mm (
5
/
32
in.) 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, page 11).
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,
page 10).
• The amplifier supports a nominal 4 Ohm speaker load impedance, and a 2 Ohm minimum speaker load
impedance.
• When connecting a subwoofer, you should use 12 AWG (3 through 4 mm
2
) 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.
