The Sinister SDX 2500 Class D Mono Block Subwoofer Amplifier is the most powerful amplifier Wet Sounds has ever built.  Employing Class D technology plus the Wet Sounds exclusive MAXED Power Supply, the Sinister SDX 2500 achieves an efficiency rating of over 87% - one of the highest available in a marine amplifier.  This means more power, less current drain, less strain on the electrical system, less generated heat.  All resulting in more playing time!

The Sinister SDX 2500 uses the same intelligent microprocessor controlled protection circuitry used on all Sinister SDX amplifiers for overvoltage/undervoltage protection, DC offset & speaker short protection, as well as thermal rollback to ensure consistent play in the harsh marine environment.  The protection circuitry is displayed in the back lit Wet Sounds shield logo.  Please refer to the user’s manual for details about the protection circuitry.

As further protection against use in the harsh marine environment, the SDX2500 includes a sealed chassis for the top mounted controls, and a four-layer conformal coated PC Board.


All Sinister amplifiers feature a fully conformal coated 4 layers pcb board, single side
power, speaker and input section, and top mounted controls with removable cover.
Sinister amplifiers have a back lit Wet Sounds shield logo with selectable illumination for red, white or blue that can be mounted horizontally or vertically for flexible amplifier placement.
Other features include high pass/low pass/full range crossovers, flexible inputs source selection for single or multiple RCA channel input, RCA pass through on 4ch and 2ch, and removable speaker plugs that accept large gauge wire. The sinister amplifiers are not only extremely powerful but also intelligent with a built in microprocessor controller for over voltage protection, under voltage protection, DC offset and speaker short protection, as well as thermal rollback to ensure consistent play in the harsh marine environment.
