We recently acquired a lot of parts from a marine distributor reducing their excess inventory. This amp is used but in great shape. We power tested this unit here at our Pompano Beach facility and found it to be 100% operational. There is some minor wear around the amp and 2 of the screws are missing from the top cover.
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 Patented 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.
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.
