Marine Audio Amplifier

The Wet Sounds SYN-DX 4 is a 2-channel Class D amplifier built for extreme marine environments. It delivers high power output from a compact chassis and includes thermal overload protection for reliability on the water. Flexible crossover controls and extended input ranges allow precise tuning for Wet Sounds speaker systems. This unit suits boat owners who need durable, high-performance amplification.

Class D Power Limits

Class D circuitry provides efficient power delivery with reduced heat generation compared to traditional designs. The amplifier produces 125 watts RMS per channel at 4 ohms and 200 watts RMS per channel at 2 ohms, both measured at greater than 1.0% THD. When bridged to mono at 4 ohms, output reaches 400 watts RMS per channel. Frequency response covers 20 Hz to 20 KHz for full-range reproduction.

Upgrade From Basic Marine Amps

This amplifier replaces entry-level marine units that lack sufficient power for demanding speaker loads or advanced tuning features. The adjustable crossovers span 50 Hz to 250 KHz at 12dB per octave for both high-pass and low-pass filters. Input sensitivity ranges from .2 V to 6.0 V, accommodating a wider variety of source units. The jump is worth it when your current amp cannot drive Wet Sounds speakers cleanly at high volume or lacks thermal protection for extended use.

Questions about this item

Should I run the SYN-DX 4 in stereo or bridge it to mono for my subwoofer?

Stereo at 4 ohms gives 125 watts per channel, stereo at 2 ohms gives 200 watts per channel, and bridged mono at 4 ohms delivers 400 watts per channel — choose the wiring that matches your speaker impedance and power needs.

What does the 125 watts RMS at 4 ohms actually deliver on the water?

It provides 125 watts of continuous power per channel into a 4-ohm load with distortion below 1.0% THD across the full 20 Hz to 20 KHz range.

How does the 0.2 V to 6.0 V input sensitivity work with my source unit?

The adjustable 0.2 V to 6.0 V range lets you match the amplifier gain to almost any head-unit or signal-processor output voltage for clean, noise-free operation.
