Detailed description

Designed for demanding marine audio systems, the Fusion Signature Series 8-channel 2000W marine amplifier (model SG-DA82000) provides a high-power audio solution for complex installations. This Class D amplifier delivers 2000 W of peak power, with a nominal RMS power of 100 W per channel at 4 Ohm or 140 W per channel at 2 Ohm across its eight channels. It can also be bridge-mode configured to deliver 280 W RMS on four channels at 4 Ohm, offering flexibility to power a variety of speakers and subwoofers.

True-Marine™ design and robustness

The Fusion Signature Series amplifier features True-Marine™ design, ensuring protection against harsh marine environments. Its printed circuits are coated with a conformal coating for enhanced resistance to elements. The die-cast aluminum chassis acts as a heat sink, with optimized fin layout to maximize surface area and improve thermal dissipation, contributing to system reliability. It weighs 5.2 kg and measures 420 mm x 210 mm x 57 mm.

Audio performance and system integration

With a frequency response of 10 Hz to 40 kHz (-3 dB at 4 Ohm), this amplifier can reproduce an extended sound spectrum. It integrates adjustable high-pass and low-pass filters from 32 Hz to 320 Hz with a 12 dB/octave slope, as well as adjustable Bass Boost from 0 to 9 dB for zones 2 and 4. These options allow precise customization of audio output for different types of speakers and subwoofers. The required power supply is 10.8 to 16 Vdc, with a maximum current draw of 100 A. The compass safe distance is 50 cm.

Positioned as a high-performance solution in Fusion’s Signature range, this amplifier stands out from basic models by its ability to handle complex multi-zone audio systems with high RMS power per channel. Compared to Class AB amplifiers, its Class D technology offers superior energy efficiency, reducing current draw and heat generation—a significant advantage for marine installations where power management is critical.

« Technical analysis of the Fusion Signature 8-channel marine amplifier »

The Fusion Signature Series 8-channel 2000W marine amplifier is a relevant option for complex audio integrations aboard pleasure craft or sport fishing vessels requiring multi-zone sound systems. Its Class D design delivers optimized energy efficiency, a critical factor in reducing the load on the vessel’s batteries compared to traditional Class AB amplifiers. This feature is particularly valuable on boats where electrical autonomy is a major concern.

This amplifier is ideal for powering multiple pairs of speakers and one or two subwoofers simultaneously, thanks to its 8-channel configuration and bridging capability. The adjustable high-pass and low-pass filtering options, along with Bass Boost on certain zones, allow precise acoustic adaptation to the boat’s environment and the type of transducers used. It must be emphasized, however, that despite its True-Marine™ design, the unit must be installed in a dry location, protected from direct spray and ambient moisture, as specified by the manufacturer. A location in a console or a ventilated technical compartment is recommended to ensure longevity and performance. The cast-aluminum heat sink design is a key advantage for thermal stability under prolonged load.

This amplifier is a sound choice for installations where sound quality, configuration flexibility, and energy efficiency are priorities, and where installation space allows compliance with the requirement for a dry environment. It serves as a central component for Fusion’s high-end audio systems, ideally complementing the Signature series speakers and subwoofers.

Frequently Asked Questions

Need help? Contact us

What is the maximum peak power of this Fusion Signature marine amplifier?

This Fusion Signature marine amplifier delivers a maximum peak power output of 2000 W.

How many output channels does this amplifier have?

The Fusion Signature marine amplifier is an 8-channel model, offering high flexibility for complex audio systems.

What is the RMS power per channel at 4 Ohm impedance?

Under a 4 Ohm impedance and a 14.4 Vdc power supply, this amplifier delivers a nominal power output of 100 W RMS per channel across its 8 channels.

What is the RMS power per channel under a 2 Ohm impedance?

When the amplifier is configured for 2-ohm speakers, it delivers a nominal RMS power output of 140 W per channel across its 8 channels.

Can I use this amplifier in bridged mode and what would the power output be?

Yes, this amplifier can be configured in bridged mode. In this configuration, it can deliver 280 W RMS on four channels at an impedance of 4 Ohms.

What is the frequency response range of this amplifier?

The amplifier's frequency response range is 10 Hz to 40 kHz (at -3 dB under a nominal 4 Ohm load), enabling extended sound reproduction.

What are the dimensions and weight of the amplifier?

The amplifier measures 420 mm x 210 mm x 57 mm and weighs 5.2 kg (with the cover installed).

What type of amplification technology is used in this model?

This amplifier uses Class D amplification technology, known for its energy efficiency and ability to deliver high power in a compact format.

Which tools are required for installing the amplifier?

For installation, you will need the following tools:

A 3 mm Allen key (for the top cover and power terminals). A 2.5 mm Allen key (for the speaker terminals). A wire stripper.

What is the required supply voltage for this amplifier?

The amplifier requires a DC supply voltage between 10.8 and 16 Vdc.

What is the maximum current draw of the amplifier?

Maximum current draw of the amplifier is 100 A.

What wire gauge is recommended for a standard installation?

For a total consumption of 85 to 105 A over a distance of 0 to 4 feet (0 to 1.2 m), a 4 AWG (21.1 mm²) power cable is recommended. It is important to consult the wire gauge chart for different distances and amperages.

What speaker cable gauge is recommended for different cable lengths?

Speaker cable gauge recommendations are as follows:

For distances from 0 to 8.5 meters (0 to 28 feet): 16 AWG (1.3 to 1.5 mm²). For distances from 8.5 to 21 meters (28 to 69 feet): 12 AWG (3 to 4 mm²).

What is the safe distance to maintain between the amplifier and a compass?

A safety distance of 50 cm (20 inches) must be maintained between the amplifier and a compass to prevent magnetic interference.

Must the amplifier be installed in a dry environment?

Yes, although designed for the marine environment, the amplifier must be installed in a dry location to ensure proper operation and longevity.

What speaker impedances are compatible with this amplifier?

This amplifier is compatible with 4 Ohm and 2 Ohm speakers per channel. In bridged mode, it is compatible with 4 Ohm speakers.

How can I connect multiple speakers to a single amplifier channel?

You can connect multiple speakers with the same impedance in parallel. To calculate the total impedance, divide the common impedance by the total number of speakers connected in parallel. For example, two 4 Ohm speakers connected in parallel will result in a total impedance of 2 Ohms.
