Marine amplifier Fusion Signature 5-channel 1,600 watts

The Fusion Signature SG-DA51600 marine amplifier delivers 1600 watts of peak power.

This amplifier is a 5-channel model designed for a complete marine audio experience.

The physical dimensions of the amplifier are 300 mm (length) x 210 mm (width) x 50 mm (height).

The frequency response of this amplifier ranges from 10 Hz to 50 kHz, ensuring detailed sound reproduction.

The RMS (Root Mean Square) power specifications are as follows:

Under 4 ohms (1% THD+N): 4 x 80 W RMS + 1 x 250 W RMSSUnder 2 ohms (1% THD+N): 4 x 130 W RMS + 1 x 330 W RMSBridged mode under 4 ohms (1% THD+N): 2 x 250 W RMS + 1 x 250 W RMS

For zones 1 and 2, you can select a low-pass filter (LPF), high-pass filter (HPF), or full range (FULL). For the subwoofer, there is a fixed low-pass filter (LPF) and a fixed subsonic filter.

Yes, the amplifier has a dedicated connection for an optional remote subwoofer level controller, which is supplied with the unit.

This amplifier requires installation of two 40 amp fuses (2 x 40A) for adequate protection.

The amplifier is equipped with power and status LED indicators. The LED displays green if the amplifier is properly powered, and red if a fault is detected.

Frequency settings for the filters are as follows:

Zones 1 and 2: LPF or HPF filter frequency is adjustable from 32 Hz to 320 Hz. Subwoofer: The LPF filter is adjustable from 32 Hz to 320 Hz and the subsonic HPF filter is adjustable from 10 Hz to 80 Hz.

Yes, the amplifier includes a bass boost function specifically for the subwoofer channel. This setting is tunable from 0 dB to 12 dB.

Use a 4 AWG (4 gauge) cable for the connection to the positive terminal (+12V) of the battery and for the connection to the ground of the boat's electrical system.

During installation, the ground wire connection must be the first cable to be connected. The +12V wire connection to the battery (via an inline fuse or circuit breaker located as close as possible to the battery) must be the last wire to be connected.

This wire must be connected to the remote start wire of your audio system's main unit (car stereo). If no such output is available, a switched 12V source must be used.

During installation, take the following precautions:

Ensure the mounting location does not interfere with the fuel tank or the boat's electrical wiring.The amplifier must be securely fastened to the boat to prevent movement or injury in the event of an accident.The location must provide sufficient airflow around the amplifier. If the amplifier is installed in an enclosed space, the use of a 3-inch fan with ducting is recommended to aid cooling.Avoid mounting the amplifier near critical navigation equipment, receiving antennas, or the boat's radio communication devices.

To adjust the input level, follow these steps:

Turn the amplifier level control to its minimum position (zero). Set the main unit volume to three-quarters of its capacity and tone settings to zero. Slowly increase the amplifier level control until you reach the desired maximum volume without any audible distortion.

Select RCA cables of the correct length and route them to the RCA outputs of the main unit. It is critical to avoid running them alongside other cable bundles or power cables, as this could introduce audio interference.

Yes, the amplifier has dedicated RCA inputs for Zone 1, Zone 2, and Subwoofer. This makes it compatible with most marine main units featuring corresponding low-level outputs.

Yes, the amplifier is equipped with a switch that lets you select the audio source for the subwoofer channel. Audio can be routed either from the SUB input RCA connectors or from the Zone 1 and Zone 2 input RCA connectors.

For safe and efficient wiring:

Ensure all cables are protected from sharp objects. Always use rubber grommets when running wires through metal panels. Protect all terminals and connections on the boat’s chassis and from each other to prevent short circuits or permanent damage to the audio system. Ensure all wiring is protected to avoid pinching or crushing, which could damage the audio system.
