My Fusion system has a loud hum or noise coming from the speakers connected to my amplifier.
This is normally caused by introduced interference through the RCA cables connected from the stereo to the amplifier and is often referred to as a ground loop. It can be caused by numerous electric sources of interference such as refrigerators, power and ground cables, LED lights etc. You can spend a lot of time searching for the source, so prevention is the best course - do not run RCA cables near any electrical equipment or power/ground cable runs.
The quickest way to resolve this is by fitting ground loop isolators on all RCA cables - this is an inexpensive way to remove the unwanted noise.

Signature Series 8 Channel Marine Amplifier
Introducing an impressive new addition to Fusion’s Signature Series amplifier range: the SG-DA82000.
Fusion Signature Series amplifiers are purpose-built for the outdoor environment. Boasting some of the most impressive environmental protection available, they deliver a Signature performance on the road like never before.
Our most efficient, stunning and powerful amplifier, the SG-DA82000 also features an Outdoor-Ready design that will resist corrosion. Its incredible 2000 Watt peak power will power up to 8 pairs of speakers at 2 Ohms (2 x 4 Ohm speakers per channel in parallel) or up to 4 pairs of speakers at 2 Ohms (2 x 4 Ohm speakers per channel in parallel) and 2 subwoofers. RCA line-level inputs allow for easy connection to new or existing systems.
The SG-DA82000 is Fusion's first 8 channel, Class-D Hi-Fi 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 outdoor environment. The SG-DA82000 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.
This product is rated Outdoor-Ready and carries a 3-year limited consumer warranty.
Class-D Amplifier Technology - The highly efficient Class-D design provides 2000-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.
2000 Watts Peak Power – With a peak power of 2000 watts, you can easily power up to 8 pairs of speakers or up to 4 pairs of speakers with 2 subwoofers.
Outdoor-Ready Design with Conformal Coated PCBs - Extending the life of your amplifiers, the Signature Series are designed specifically for use on the road, with conformal coated PCBs to provide extra protection from the 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.
Outdoor-Ready Design - Signature Series amplifiers are perfect for the outdoor environment, and carry a 3-year warranty.
Class-D Amplifier Technology
Our most efficient, stunning and powerful amplifier series features Class-D Technology. The highly efficient 2000 Watt amplifier design ensures lower battery drain with a higher output in comparison with Class-AB amplifiers. This delivers increased power to the connected speakers and/or subwoofers, extending your audio entertainment experience to a whole new level.
The Outdoor-Ready Standard
As an Outdoor-Ready product, the Signature Series amplifiers are designed and engineered for harsh outdoor environments. Once a product has been subject to rigorous environmental testing and passed our stringent Outdoor-Ready approval process, it is awarded the accreditation and recognized with an industry-leading 3 year consumer warranty.
Rigid Aluminum Alloy Heat Sink
Providing increased efficiency without compromising the form factor, the Signature Series amplifier range features a rigid aluminum alloy heat sink. Greater heat dissipation and unquestionable efficiency is achieved with molded fins forming a singular die-cast chassis, with the layout precisely calculated to increase the surface area of the heat sink.
