Wet Sounds Sinister Series Amplifier

Flagship power. Elite clarity. Built for marine dominance.

The Wet Sounds Sinister Series Amplifier represents the absolute peak of marine audio performance. Designed for those who demand uncompromising power, efficiency, and control, Sinister amplifiers combine Wet Sounds’ exclusive Class D power supply with patented MAXED™ power technology to deliver massive output with remarkably low current draw.

The result is more usable power, less heat, and longer playtime on the water — without overloading your electrical system.

Housed in a single, full cast-aluminum chassis, every Sinister amplifier offers superior cooling, corrosion resistance, and simplified installation. Engineered specifically for marine environments, the Sinister Series goes far beyond typical automotive amplifiers, delivering clean, stable, distortion-free performance even during extended high-output sessions.

This is Wet Sounds at its highest level.
