Description
Explore and enjoy this season with a 4-channel, 1400-watt Signature marine amplifier from Fusion. Connect up to two speakers per channel at 2 ohms, or bridge two channels at 4 ohms for increased power. Purpose-built for the marine environment, the Signature Series marine amplifiers feature some of the most impressive environmental protection available — delivering a Signature performance out on the water.
DSP Technology
The Fusion SG-DA41400 comes with Fusion DSP technology. Using a compatible stereo like the MS-RA770, you can select the equipment you have and the DSP audio will automatically be set. Delivering your music the way it is supposed to be heard.
3-Year Warranty
Fusion stands behind its products by offering a 3-year warranty on all of its Signature amplifiers. Keep the music going year after year with the best marine-grade amplifiers.
Conformal Coated PCBs
All of Fusion's Signature amplifiers are ready for the heavy seas. Helping to extend the life of your amplifiers, the Signature Series amplifiers are designed with conformal coated PCBs to provide extra protection from the marine elements.
Rigid Aluminum Heat Sink
For increased efficiency, the rigid aluminum alloy heat sink is 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.
