Wet Sounds SD6 Marine Amplifier 6 Channel Class D 6x185W

Marine amplifier for six-channel audio

The Wet Sounds SD6 is a Class D marine amplifier designed for boats that need clean power across six independent channels. It targets owners who want full-range output for multiple speaker zones without the heat and current draw of traditional designs. The unit suits installations where electrical-system headroom is limited and reliability in salt-spray environments matters.

185 watts per channel at four ohms

Each channel delivers 185 watts RMS at four ohms and 290 watts at two ohms, while bridged operation provides 585 watts across three channels at four ohms. The MAXED power supply keeps current draw to 95 amps in stereo at four ohms and 168 amps at two ohms or bridged, reducing strain on the alternator and battery bank. Frequency response spans 8 hertz to 35 kilohertz with a signal-to-noise ratio above 87 dB A-weighted, giving usable bandwidth for both sub-bass and high-frequency detail.

Compact cast-aluminium chassis

A single full-size chassis fits all Sinister models, simplifying bracket planning and cable routing in tight gunwale or helm spaces. High- and low-pass crossovers adjust from 30 to 300 hertz at 12 dB per octave, and a variable bass boost adds up to 12.5 dB between 27 and 110 hertz. Input sensitivity accepts 0.2 to 6.1 volts, while the remote level control sweeps 0 to minus 61 dB, allowing integration with most source units without extra line drivers. Over-voltage protection triggers at 15.6 volts.
