Thank you for purchasing the Wet Sounds SinisterTM Series amplier. Wet Sounds
Sinister series of marine ampliers represents the pinnacle in 12 volt amplier
design.
The Sinister™ ampliers are the highest power to size ampliers anywhere in the
world for marine use. The SinisterTM ampliers use superior performance circuitry
by utilizing Wet Sounds exclusive Class D technology combined with Wet Sounds
MAXED™ Power supply. The MAXED power supply is a patent pending technology
designed to provide high efciency levels never thought to be achievable in a
mobile audio amplier. What this means to you. Less current draw, less strain on
the electrical system, less generated heat. All this results in more play time!
All Sinister ampliers feature a fully conformal coated 4 layer pcb board, single
side power, speaker and input section, and top mounted controls with removable
cover. SinisterTM ampliers have a back lit Wet Sounds shield logo with selectable
illumination for red, white or blue that can be mounted horizontally or vertically for
exible amplier placement.
The SinisterTM ampliers are not only extremely powerful but also intelligent
with a built in microprocessor controller for overvoltage protection, undervoltage
protection, DC offset and speaker short protection, as well as thermal rollback to
ensure consistent play in the harsh marine environment. One of the most amazing
aspects of the SinisterTM ampliers design is the efciency rating. The SDX2500
achieves an efciency rating at full 4 ohm rated power of over 87%. This translates
into less current draw and less generated heat. Over twice that of a conventional
class AB amplier.
CONGRATULATIONS!

The Laws of Nature
Your amplier does NOT make power; it converts power, or current, from your
boats electrical system and converts it into high power musical energy. If the amp
can’t get all the power it needs it will not produce its full output. Your Wet Sounds™
amplier will produce full output longer than other amplies on the market today.
Should your voltage or current drop too low the amplier will drop below the rated
output.
Make sure your boats charging system is in good working order. Any high
performance audio amplier will increase the demand on your alternator and
battery. If you are unsure have you charging system checked system testing by a
professional technician.
SUPPLYING ENOUGH POWER
RUNNING THE WIRE CABLES
**Always keep the signal cable and the power cables separated to prevent
the possibility of inducing noise into the system**
Carefully run the power and the signal cables through the boat. Always keep all
the wire tight and tied down to prevent the power wire from shorting and reduce
the risk of re. A 1/0 AWG or larger wire should be used for power and ground
connections. We recommend a fuse to be installed on the power wire within 18
inches of the battery for safety.
