Detailed description

The Fusion Signature SG-DA12250 marine monobloc amplifier is designed for marine sound systems, delivering a maximum power output of 2250 watts. Featuring Class-D amplification technology, it ensures reduced power consumption while providing audio performance in demanding marine conditions.

Power and versatility

This monobloc amplifier delivers 1100 watts RMS x 1 at 1 ohm, 850 watts RMS x 1 at 2 ohms, and 500 watts RMS x 1 at 4 ohms, with an input voltage of 14.4V and a THD+N below 1%. Its frequency response ranges from 10 Hz to 320 Hz (-3 dB at rated power under 4 ohms). The configurable 1-ohm impedance is specifically suited for powering a subwoofer at maximum output.

True-Marine™ marine-grade design

The SG-DA12250 complies with True-Marine™ design standards, ensuring resistance to harsh marine environments, including salt spray, temperature fluctuations, vibrations, and UV exposure. The printed circuits are coated with a conformal coating for enhanced protection against marine elements. The heat sink is made of rigid aluminum alloy, cast into an aluminum chassis, featuring fins for efficient thermal dissipation. The polished stainless-steel control panel resists corrosion and conceals connections and adjustments.

Advanced audio features

For customized sound quality, the amplifier includes adjustable input gain (0.3 V - 8 V RMS), variable low-pass filter (32 Hz - 320 Hz), variable subsonic filter (10 Hz - 80 Hz), and variable Bass Boost (0-12 dB at 45 Hz). It features RCA line-level inputs and an RCA "pass-thru" output for connecting a secondary amplifier. Power is protected by three 40-amp ATC fuses. Dimensions are 300 mm (W) x 210 mm (D) x 50 mm (H), and it operates on 10.8-16 VDC. It comes with a 3-year warranty.

Frequently Asked Questions

Need help? Contact us

What is the peak power output of this Fusion marine amplifier?

The Fusion Signature marine monoblock amplifier delivers 2250 watts RMS with a peak power of 2250 watts.

What are the physical dimensions of the Fusion SG-DA12250 amplifier?

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

What is the RMS power of the amplifier at different impedances?

500W RMS x 1 channel at 4Ω with 1% THD+N850W RMS x 1 channel at 2Ω with 1% THD+N1100W RMS x 1 channel at 1Ω with 1% THD+N

What type of amplifier is the Fusion SG-DA12250?

This is a marine Class D amplifier.

What is the frequency response range of this amplifier?

The amplifier's frequency response is 10 Hz to 320 Hz.

What cable gauge is recommended for the +12V power supply and ground?

Use a 4 AWG (4 gauge) cable for the +12V connection and for the ground connection to the vessel's electrical system.

How should I connect the amplifier to the boat's battery?

The amplifier must be connected directly to the positive terminal (+12V) of the vessel’s battery using a 4 AWG cable. A fuse or circuit breaker must be installed as close as possible to the battery. This is the last wire to connect during installation.

What are the important mounting guidelines for this amplifier?

During installation, ensure the amplifier is securely mounted to the vessel and that the mounting location provides adequate airflow. If the amplifier is installed in an enclosed space, a 3-inch fan with ducting must be used to facilitate airflow. Avoid mounting it near critical navigation equipment, receiver antennas, or radio communication devices.

How to adjust the amplifier gain level?

To adjust the gain level, first turn the amplifier level control to zero. Set the main unit volume to three-quarters and adjust the tone controls to zero. Then slowly adjust the amplifier level control until you reach the desired maximum volume without distortion. If the sound distorts, lower the control.

Can I connect other amplifiers to this one?

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

What are the adjustment ranges for the low-pass filter (LPF) and the subsonic filter?

The low-pass filter (LPF) is adjustable from 32 Hz to 320 Hz. The subsonic filter is adjustable from 10 Hz to 80 Hz.

Does the amplifier have a bass boost function?

Yes, it has a variable Bass Boost function that allows increasing the level at 45 Hz from 0 to +12 dB gain. This function is part of the FUSION low-frequency control (F.L.F.C.).

What type of fuses are required for this amplifier?

The SG-DA12250 amplifier requires 3 x 40A fuses.

What do the power and status LED indicators mean?

A green LED indicates that the amplifier is correctly powered. A red LED indicates a fault.

How to ground the amplifier?

The ground connection must be made directly to the vessel's ground system using a 4 AWG cable. This is the first wire to connect during installation.

How does the Remote Turn-On connection work?

This connection allows you to turn the amplifier on and off. It requires a switched positive source (+12V), typically found on the main unit as a remote output. If unavailable, a switched 12V source must be used.

What to do if the amplifier does not power on and the power LED is off?

Check the fuses and connections on the +12V battery power cable. Also ensure the remote start connections to the main unit are correct. If a fuse is blown, replace it with one of the correct type and amp rating.

What to do if the amplifier is hot but not working?

If the amplifier is too hot, move it to a better-ventilated location or ensure adequate airflow. Lower the main unit's volume. Also check that no speaker wire is short-circuiting with other wires.

What speaker impedances are compatible with this amplifier?

This amplifier is designed to operate with loads of 1 ohm, 2 ohms, or 4 ohms impedance, providing different RMS power outputs for each impedance.

Which basic tools are required for installation?

Basic tools that may be required include an electric drill, crimping pliers, a set of Allen keys, wire strippers, a utility knife, a reciprocating saw, a jigsaw, a nibbler, a flathead screwdriver, electrical tape, a Phillips screwdriver, and silicone sealant.
