INSTALLATION GUIDELINES
- Ensure the +12V lead is disconnected from the battery before you connect any new equipment.
- Ensure the mounting location will not interfere with the gas tank or electrical wiring.
- Ensure the Amplifier is securely fastened to the vessel to prevent injury in the event of an accident.
- Ensure all wiring is protected to avoid pinching or crushing which could result in damage to the audio system.
- Ensure the mounting location has sufficient air flow around the amplifier. If the amplifier is mounted in an enclosed space a 3” fan with ducting should be used to aid in air flow.
- Ensure you use the recommended gauge wire/cable for all amplifier connections.
- Note: we do not recommend mounting your amplifier in close proximity to other bridge-mounted equipment critical to safe navigation of your vessel, in close proximity to receiving antennas, or near radio-communications equipment mounted on your vessel.
+12V CONNECTION
FUSION amplifiers should be connected directly to the +12V battery terminal via a 4 gauge cable with an inline fuse or circuit breaker as close to the battery as possible.
GROUND CONNECTION
Connect directly to the vessel’s earth system via a 4 gauge cable. NOTE: This
is the first wire to connect up during the installation.
REMOTE TURN-ON CONNECTION
This connection turns the amplifier on & should be connected to the remote
turn on wire from the Head Unit. If one is not available a switched 12v source
must be used.
WIRING
Ensure the audio system is turned off before making any connections to the
amplifier, speakers or source unit, failure to do so could result in permanent
damage to the audio system.
When wiring the FUSION amplifier ensure that the cable is protected from sharp objects and always use rubber grommets when wiring through metal panels.
Ensure all terminals and connections are protected from the vessel chassis and from each other as failure to do so could result in permanent damage to the audio system.
RCA INPUTS
Choose the correct length RCA cable & run them to the RCA outputs of the
source/head unit, avoiding running beside other looms & or power cable.
LEVEL CONTROL
This control is used to match the input level of the amplifier to the output
level of the head unit. We recommend the following method. NOTE: Remove screws
and the top cover of amplifier to access controls.
- Turn the amplifier level to zero
- Turn the volume of the head unit to 3/4 and the tone settings to zero
- Adjust the level control until the desired maximum volume is achieved without distortion.
- Failure to follow these steps may cause permanent damage to the audio system.

CONTROL DESCRIPTIONS
-
SPEAKER OUTPUT:
Connect your speakers to these terminals. -
RCA OUTPUT:
Use these RCA connectors to connect to a secondary amplifier. This output is a pass-thru connection derived from the RCA input connectors so that the signal level and frequency response is the same as the original input signal. -
ZONE 2 RCA INPUT:
Connect these RCA connectors to a head unit with low level output connection. -
ZONE 1 RCA INPUT:
Connect these RCA connectors to a head unit with low level output connection.
-
POWER AND STATUS LED’S:
This displays “green” if the amplifier has been correctly powered up and ‘red’ if any faults are present. -
FUSES:
Please ensure the correct type of fuse is fitted. For SGDA41400 2 x 40A fuses. -
+12V CONNECTION:
Connect directly to the vessel battery positive (+) terminal via a 4 gauge cable, with an inline fuse or circuit breaker at the battery end. NOTE: This is the last wire to connect up during installation. Damage could result if this is not done. -
REMOTE TURN-ON CONNECTION:
This terminal is for turning the amplifier on & off. The remote input requires a switched positive (+12V) to power ‘ON’ the amplifier. This can usually be found on the rear of the head unit in the form of a remote output. -
GROUND CONNECTION:
Connect directly to the vessel’s earth system via a 4 gauge cable. NOTE: This is the first wire to connect up during the installation. -
ZONE 2 LEVEL:
This allows level adjustment of the zone 2 input signal. Use this control to directly match the head unit to the amplifier. To set this control correctly, turn the amplifier level to MIN and the head unit to 3/4 volume, with the tone settings on zero, then slowly turn up the level control towards the MAX end of the control. NOTE: If the sound becomes distorted, turn this control down. -
BASS BOOST:
The Bass Boost is a variable control to increase the level at 45Hz from 0 – +12dB of gain. Adjust this control with extreme care. -
ZONE 1 LEVEL:
This allows level adjustment of the zone 1 input signal. Use this control to directly match the head unit to theamplifier. To set this control correctly, turn the amplifier level to MIN and the head unit to 3/4 volume, with the tone settings on zero, then slowly turn up the level control towards the MAX end of the control. NOTE: If the sound becomes distorted, turn this control down. -
ZONE 2 FILTER FREQUENCY:
This sets the crossover frequency point for the zone 2 filter between 32Hz and 320Hz. NOTE: Failure to correctly set could result in speaker damage. -
ZONE 2 FILTER SELECTION:
This switch selects the type of filter used for the zone 2 audio signal. Either Low Pass, High Pass or Full Range can be selected. The Low Pass filter is designed to filter out all mid to high frequencies that only full range speakers should produce. The High Pass filter is designed to filter out all low frequencies that only subwoofers should produce. Full Range allows all frquencies. -
ZONE 1 FILTER SELECTION:
This switch selects the type of filter used for the zone 1 audio signal. Either Low Pass, High Pass or Full Range can be selected. The Low Pass filter is designed to filter outall mid to high frequencies that only full range speakers should produce. The High Pass filter is designed to filter out all low frequencies that only subwoofers should produce. Full Range allows all frquencies. -
ZONE 1 FILTER FREQUENCY:
This sets the crossover frequency point for the zone 1 filter between 32Hz and 320Hz. NOTE: Failure to correctly set could result in speaker damage.

PARALLEL VOICE COIL WIRING (2 OHM OPERATION)
To wire a 4 Ohm DVC subwoofer in parallel to get 2 Ohm, use two short pieces
of speaker wire and link the positive from one coil to the positive of the
second coil, and do the same for the negative as shown below. Then wire the
amplifier to opposite sides of the subwoofer in order to equalise any
connection resistance.
