Wet Sounds Sinister-SDX 2500 – Flagship Class D Mono Block Subwoofer Amplifier

Maximum output. Intelligent control. Built without compromise.

The Wet Sounds Sinister-SDX 2500 is the most powerful amplifier Wet Sounds has ever built. Designed for elite-level marine audio systems, this flagship Class D mono block delivers up to 2500 watts RMS at 1Ω while achieving over 87% efficiency—one of the highest ratings in marine amplification.

Powered by Wet Sounds’ exclusive MAXED™ Power Supply, the SDX 2500 produces massive low-frequency output with reduced current draw, lower heat generation, and minimal strain on your electrical system. The result is longer playtime, cleaner power delivery, and relentless bass performance in the harshest marine environments.

Engineered specifically for life on the water, the SDX 2500 features intelligent, microprocessor-controlled protection circuits for over-voltage, under-voltage, DC offset, speaker short, and thermal rollback protection. A sealed control chassis and four-layer conformal-coated PCB provide additional defense against moisture, corrosion, vibration, and heat.

This is not just power — it’s controlled, intelligent dominance.
