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.
Key Features:
- 800W total RMS output — 125W x 4 @ 4 ohms | 200W x 4 @ 2 ohms | 400W x 2 bridged @ 4 ohms
- Full-range Class-D design — 2-ohm stable in stereo, 4-ohm stable bridged
- Supports 4/3/2-channel operation for flexible system configurations
- Variable high- and low-pass crossovers — adjustable 50–250 Hz at 12 dB/octave
- Extended input sensitivity — 0.2V to 6.0V, compatible with virtually any head unit
- 3-way protection circuitry — thermal overload, overload, and speaker short protection
- LED power (blue) and protect (red) indicators for quick diagnostics
