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.

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.
