Marine amplifier Fusion Signature 4-channel 1400 watts

The Fusion Signature SG-DA41400 amplifier has dimensions of 300 mm (length) x 210 mm (width) x 50 mm (height). In inches, this is approximately 11-13/16" x 8-1/4" x 2".

This Fusion Signature SG-DA41400 marine amplifier delivers a peak power of 1400 Watts.

The frequency response of the Fusion Signature SG-DA41400 amplifier ranges from 10 Hz to 65 kHz.

The Fusion Signature SG-DA41400 amplifier delivers the following RMS power ratings:

150 Watts RMS x 4 channels at 4 Ohms with 1% THD+N
220 Watts RMS x 4 channels at 2 Ohms with 1% THD+N
440 Watts RMS x 2 channels at 4 Ohms in bridged mode with 1% THD+N

This Fusion Signature marine amplifier is a 4-channel model.

The Fusion Signature amplifier offers selectable crossover filters for zones 1 and 2. You can choose between a low-pass filter (LPF), a high-pass filter (HPF), or a full-band mode (FULL). The crossover frequencies are adjustable between 32 Hz and 320 Hz.

Yes, the Fusion Signature amplifier includes a variable Bass Boost function for Zone 2. It allows increasing the level at 45 Hz from 0 to +12 dB. It is recommended to adjust this control with extreme caution.

The Fusion Signature amplifier is equipped with power and status LED indicators. A green light indicates the amplifier is correctly powered, while a red light signals a fault.

It is recommended to use a 4 AWG gauge cable for the positive (+12V) connection to the battery and for the ground connection to the boat's electrical system.

The ground cable must be connected directly to the boat's ground (earth) system. It is the first wire to connect when installing the amplifier.

The remote turn-on wire must be connected to the "remote turn-on" output wire of your main unit (marine stereo). If this output is not available, a switched 12V source must be used to power the amplifier.

Yes, several precautions must be taken:

Ensure the location does not obstruct the fuel tank or electrical wiring. The location must allow sufficient airflow around the amplifier. If the amplifier is installed in an enclosed space, a 3-inch fan with ducting may be required to improve airflow. Securely mount the amplifier to the boat to prevent injury in case of an accident. Avoid mounting it near critical navigation equipment, receiving antennas, or radio communication devices.

To adjust the input level:

Set the amplifier level to zero (MIN). Set the main unit’s volume to three-quarters of its maximum and tone settings to zero. Slowly increase the amplifier level control toward maximum until the desired volume is reached without distortion. If the sound distorts, reduce the control. Note that accessing these controls requires removing the screws and the top cover of the amplifier.

The Fusion Signature SG-DA41400 amplifier requires two 40-amp fuses (2 x 40A). Ensure you use the correct fuse type.

To protect the wiring:

Ensure all cables are protected to prevent pinching or crushing.Always use rubber grommets when running cables through metal panels.Protect all terminals and connections from the boat’s chassis and from each other to prevent permanent damage to the audio system.

Yes, this amplifier is compatible with different speaker impedances. It can operate with speakers from 4 to 8 Ohms in 2-channel configuration, and from 2 to 8 Ohms in 3- or 4-channel configurations (including bridged mode).

Yes, this amplifier has RCA outputs that can be used to connect a secondary amplifier. This output is a "pass-thru" connection, meaning the signal level and frequency response are identical to the original RCA input signal.

This amplifier is compatible with main units featuring low-level RCA outputs. It also requires a "remote turn-on" output or a switched 12V source to power on.

Yes, this amplifier can be used to power subwoofers via its bridged mode, which delivers 440 Watts RMS x 2 at 4 Ohms. Additionally, the selectable crossover filters (LPF) and the Bass Boost on Zone 2 are suitable for optimizing performance with subwoofers.
