		            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.   |
