Fusion SG-DA61 Zone Amplifier — Add a Powerful Audio Zone to Your Vessel
The Fusion SG-DA61 is a dedicated single-channel marine zone amplifier designed to extend high-quality audio to an additional zone on your boat without overloading your head unit. Delivering 650 W RMS into 4 ohms, it's the right choice when you need clear, loud sound in a second cabin, cockpit, or flybridge.
Built to survive the marine environment, the SG-DA61 features a conformal-coated circuit board and is engineered to resist salt fog, UV exposure, vibration, and temperature extremes. The ignition-protected design meets NMMA certification requirements, making it safe for use near fuel systems.
Easy Tune — Set It and Forget It
Fusion's Easy Tune technology automatically optimizes audio settings for the speakers connected to it — no manual EQ fiddling required. Setup is handled once through the Fusion-Link™ app on a compatible smartphone, then the amplifier handles everything from there.

Parts Desk Insights
Best use case: This amplifier is the ideal single-zone add-on for boaters who already have a Fusion head unit and want to push sound to a secondary location — a cockpit, aft deck, or below-deck cabin — without running a full multi-channel system. It pairs especially well with a pair of 4 Ω coaxial marine speakers in a confined space where a compact, weather-tough amp is needed.
Common questions: Customers frequently ask whether this unit replaces their head unit amplifier — it does not; it is a zone expansion amplifier intended to be used alongside a Fusion source unit. Customers also ask about speaker pairing: with 2 Ω stability, you can wire two 4 Ω speakers in parallel per channel. Easy Tune setup requires the Fusion-Link™ app and a Bluetooth-capable smartphone.
