The Sinister amplifiers are the highest power to size amplifiers anywhere in the world for car or marine use. The Sinister amplifiers use superior performance circuitry by utilizing Wet Sounds exclusive Class D Power Supplies combined with Wet Sounds MAXED Power supply. The MAXED power supply is a patent pending technology designed to provide high efficiency levels never thought to be achievable in a mobile audio amplifier. What this means to you. Less current draw, less strain on the electrical system, less generated heat. All this results in more play time! The Sinister amplifiers share one size full cast aluminum chassis for all models making installation a breeze and the ability to have a clean install.
Sinister amplifiers feature a fully conformal coated 4 layers pcb board, single side power, speaker & input section, & top mounted controls with removable cover. In addition, high pass/low pass/full range crossovers, flexible inputs source selection for single or multiple RCA channel input, & removable speaker plugs make the Sinister Series a proper amp for proper installs.
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 & speaker short protection, as well as thermal rollback to ensure consistent play in the harsh environments. Wet Sounds has taken every measure to ensure that their amplifiers are Built to Last.
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. This is perfect for installations where you are not having to re-wire just to get the logo straight. The Wet Sounds shield logo badge not only looks great but also provides the amplifier status through its acrylic spacer.
