• Peak Power (Watts): 2250
• Frequency Response: 10Hz – 320Hz
• Dimensions (mm): 300(l) x 210(w) x 50(h) (11-13/16 x 8-1/4 x 2)
• Power Ratings:
  • 500W RMS x 1 @ 4Ω 1% THD+N

Product Usage Instructions

1. Disconnect the +12V lead from the battery before connecting any new equipment.
2. Ensure the mounting location does not interfere with the gas tank or electrical wiring.
3. Securely fasten the amplifier to the vessel to prevent injury in the event of an accident.
4. Protect all wiring to avoid pinching or crushing, which could result in damage to the audio system.
5. Ensure the mounting location has sufficient air flow around the amplifier. If mounted in an enclosed space, use a 3-fan with ducting to aid in air flow.
6. Use the recommended gauge wire/cable for all amplifier connections.
7. Avoid mounting the amplifier in close proximity to other bridge-mounted equipment critical to safe navigation, receiving antennas, or radio-communications equipment on the vessel.
8. +12V Connection: Connect the amplifier directly to the +12V battery terminal using a 4 gauge cable with an inline fuse or circuit breaker as close to the battery as possible.
9. Ground Connection: Connect directly to the vessel’s earth system using a 4 gauge cable. This should be the first wire to connect during installation.
10. Remote Turn-On Connection: Connect to the remote turn-on wire from the Head Unit. If not available, use a switched 12V source.
11. RCA Inputs: Choose the correct length RCA cable and run them to the RCA outputs of the source/head unit, avoiding running beside other looms or power cable.
12. Level Control: This control is used to match the input level of the amplifier to the output level of the head unit. Follow these steps:
13. Turn the amplifier level to zero.
14. Turn the volume of the head unit to 3/4 and tone settings to zero.
15. Adjust the level control until the desired maximum volume is achieved without distortion.
16. Failure to follow these steps may cause permanent damage to the audio system.
17. Crossover Table:
    • Crossover Type: All Fixed LPF and Fixed Subsonic
    • Crossover Frequency: LPF Tunable – 32Hz – 320Hz, Subsonic Tunable – 10Hz – 80Hz
    • Bass Boost: Tunable – 0dB to 12dB
18. Troubleshooting:
    • Problem: Amplifier not switching on, Power LED not ‘on’.
    • Possible Reason: No +12V to power wire, no power to remote wire, fuse broken, fuse on amplifier blown, amplifier too hot.
    • Solution: Check fuses and connections to the battery, check remote on connections to the head unit, replace fuse with correct type and amperage, move amplifier to a vented area.
    • Problem: Amplifier not working, but Power LED is ‘on’, no sound.
    • Possible Reason: Speaker wires shorted, no RCA signal, gain control not set up, head unit off or low volume, amplifier speakers.
    • Solution: Check that there are no speaker wires shorted to other wires, check RCA connection to head unit, ensure you have set up the amplifier gain level control, check head unit volume level, check all power, remote on, and ground connections, check speaker connections.

INSTALLATION GUIDELINES

1. Ensure the +12V lead is disconnected from the battery before you connect any new equipment.
2. Ensure the mounting location will not interfere with the gas tank or electrical wiring.
3. Ensure the Amplifier is securely fastened to the vessel to prevent injury in the event of an accident.
4. Ensure all wiring is protected to avoid pinching or crushing which could result in damage to the audio system.
5. 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.
6. Ensure you use the recommended gauge wire/cable for all amplifier connections.
7. 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.

1. Turn the amplifier level to zero
2. Turn the volume of the head unit to 3/4 and the tone settings to zero
3. Adjust the level control until the desired maximum volume is achieved without distortion.
4. Failure to follow these steps may cause permanent damage to the audio system.

CONTROL DESCRIPTIONS

1. SPEAKER OUTPUT:
   Connect your speakers to these terminals.
   NOTE: The positive (+) and negative (-) are internally linked.

2. REMOTE LEVEL CONTROL CONNECTION:
   Connect the optional (supplied) Remote Level Controller to this socket.

3. RCA INPUT:
   Connect these RCA connectors to a head unit with a low level output connection.

4. 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.

5. POWER AND STATUS LED’S:
   This displays “green” if the amplifier has been correctly powered up and ‘red’ if any faults are present.

6. FUSES:
   Please ensure the correct type of fuse is fitted. For SG-DA12250 3 x 40A fuses.

7. +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.

8. 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.

9. 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.

10. LEVEL CONTROL:
    This allows level adjustment of the 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.

11. SUBWOOFER LP FILTER FREQUENCY:
    This sets the crossover frequency point for the subwoofer channels’ low pass filter between 32Hz and 320Hz.

12. FUSION LOW FREQUENCY CONTROL:
    The FUSION Low Frequency Control (F.L.F.C.) is a dual stage control interface. The combination of a Subsonic filter & a Bass Boost control allows precise shaping of the audio signal for your subwoofer(s). The Subsonic filter is essentially a high-pass crossover which blocks the frequency signal from 10Hz – 80Hz. This signal often contains no music & its removal will improve subwoofer control. The Bass Boost is a variable control to increase the level at 45Hz from 0 – +12dB of gain. Adjust these controls with extreme care.
