Garmin Fusion Signature SG-DA61500 Boat Amplifier, 6 Channels

Garmin Fusion Signature SG-DA61500 Marine Amplifier, 6 Channels

The Garmin Fusion Signature SG-DA61500 is a class D marine amplifier with 6 channels, designed to deliver increased efficiency and high power output with low energy consumption. It can power up to six pairs of speakers or combinations with subwoofers, making it ideal for complex onboard audio systems. Integrated features include variable bass boost, subsonic filter, and variable low-pass/high-pass filters for full control over sound.

The housing is made with a cast aluminum alloy heat sink, ensuring efficient heat dissipation and operational reliability. PCBs with protective coating and True-Marine design provide resistance to salt fog, UV radiation, vibrations, and high temperatures. The glossy stainless steel finish protects the connections and completes the premium look of the installation. The amplifier is stable at 2Ω and supports bridging between channels.
