The Wet Sounds SYN-DX4 is a full-range, 4-channel Class-D marine amplifier built for serious audio performance on the water and on the trail. Part of the SYN-DX Series, it delivers 800 watts total RMS power from a compact, marine-hardened chassis — making it an ideal match for Wet Sounds speakers as well as a wide range of third-party marine audio systems.
Class-D efficiency means powerful, clean output with reduced current draw, while a smart microprocessor and conformal-coated PCB provide dependable operation in the harshest marine environments, protecting against moisture, salt, vibration, and temperature extremes. The sealed, salt water-resistant extruded aluminum chassis and stainless steel hardware are built to last season after season.
