FUSION Signature Series 5-channel Amplifier SG-DA51600

The power amplifier has been specially developed to meet the harsh requirements of the marine sector and delivers first-class performance even under adverse conditions at sea. This 5-channel Signature Series amplifier has a peak output of 1600 watts and can be used with up to four pairs of speakers and a subwoofer. Use up to two speakers per channel at 2 ohms, or bridge two channels to achieve a higher output at 4 ohms.

High efficiency class D amplifier
The 5-channel amplifier is battery friendly and has greater performance compared to AB-class amplifiers. It's also highly efficient, delivering more power to the connected speakers and subwoofers. The result is an audio quality that is second to none.

A variety of features in a compact design
The amplifiers feature numerous specs such as an integrated variable bass boost, subsonic filter and variable filters for treble and bass to ensure outstanding performance and protection of the entire system.

Coated PCBs to provide extra protection from the marine elements
To extend the life of your amplifiers the series feature conformal coated PCBs, giving them the best protection from the rough conditions at sea.

Optimal cooling and heat dissipation
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.

Rugged construction
All sensitive components of the control panel, such as cable connections, switches and settings controls are well protected by the polished stainless-steel control panel cover. In addition, the high-quality design provides an attractive finish to complement any installation.

True-Marine accredited
Designed and built for the harshest marine environments. The speakers have undergone extensive testing and environmental checks and are True Marine accredited. They are also rated IP65 for water and dust ingress protection and tested for salt fog, temperature, vibration and UV.
