QAR 0.00

The Fusion Signature Series marine amplifiers are purpose-built for the marine environment. Boasting some of the most impressive environmental protection available, they deliver a Signature performance on the water like never before.

Introducing one of our most efficient and stunning marine amplifiers, the SG-DA41400. Its True-Marine design will resist corrosion, and the incredible 1400 Watt peak power will power either four Signature speakers, or two Signature speakers and a subwoofer with ease. Dedicated channel and bridging options are also available to create your own configuration.

The SG-DA41400 is a 4 Channel, Class-D Hi-Fi marine amplifier. The key benefit of a Class-D amplifier is that it has a low battery drain with high output, making this the perfect amplifier for the marine environment. The SG-DA41400 also has conformal coated PCBs for maximum product life and performance, plus the amplifier chassis is a heat sink, to reduce component core temperature and increase efficiency.

Undeniably a stand-out piece, the stunning stainless steel mirror control panel cover conceals and protects all cable connections and setting controls, with an attractive finish to complement any installation.

The zone 1 and 2 outputs include four speaker channels plus a subwoofer. RCA line-level inputs allow for easy connection to new or existing systems.

This product is rated True-Marine and carries a 3-year limited consumer warranty.


Class-D Amplifier Technology – The highly efficient Class-D design provides 1400-Watts peak power whilst drawing less current than a standard Class-AB amplifier. This design provides increased efficiency and power output to your speakers, letting you enjoy your music for longer.

1400 Watts peak power – Easily power 4 speakers, or 2 speakers and a subwoofer with a peak power of 1400 Watts.

Marine-Ready Design with Conformal Coated PCBs – Extending the life of your amplifiers, the Signature Series are designed specifically for marine use with conformal coated PCBs to provide extra protection from the marine elements.

Rigid Aluminum Alloy Heat Sink – Molded to form a singular die-cast chassis, the fin layout is calculated with precision to increase the surface area of the heat sink and improve heat dissipation.

Stainless Mirror Finish – The polished stainless-steel control panel cover conceals and protects all cable connections and settings controls whilst providing an attractive finish to complement any installation.

Speaker Configuration – Whether you require 2 Ohms per channel or 4 Ohms bridged, your Signature Series amplifier has your installation options covered to achieve the optimum output levels.

Connect up to two speakers per channel at 2 Ohms, or for extra power, bridge two channels at 4 Ohms to connect two subwoofers.

Zone Designation – To align with the Fusion entertainment system zone philosophy, the input and output connections are labelled as zones.

True-Marine Design – Signature Series amplifiers are perfect for the marine environment, and carry a 3-year warranty.
