Connecting Full-Range Speakers or a Subwoofer to the Amplifier
NOTICE
You should connect only a 4 Ohm full-range speaker or subwoofer to the amplifier when using the high power
adapter. Connecting a 2 Ohm subwoofer may cause damage to the amplifier or subwoofer.
You must install the provided high power adapter on the speaker terminal block when connecting a full-range
speaker or subwoofer to a zone. This adapter guarantees that the correct speaker terminals are connected and
it signals to the amplifier that the zone is operating in high-power mode. If needed, you can purchase additional
adapters from your Fusion dealer.
1 Place the high power adapter over an empty speaker terminal block and press until it clicks in place.
2 Route 12 AWG (3 through 4 mm
2
) marine-grade, fully-tinned copper speaker wire (not included) to the full-
range speaker or subwoofer and the amplifier.
NOTE: You should label both ends of the speaker wire so you can easily identify which wires route to which
speakers.
3 Connect the speaker wire to the full-range speaker or subwoofer, observing polarity.
NOTE: Incorrectly connecting the speaker wire by crossing the polarity may result in poor sound quality.
4 Using a #0 Phillips or a 3 mm (
1
/
8
in.) flat (slotted) screwdriver, connect the speaker wires to the speaker
terminal blocks, observing the polarity labeled on the high power adapter cover.
