FOLLOWING THIS INSTRUCTIONS MAY CAUSE INJURIES TO THE USER OR 

DAMAGE TO THE EQUIPMENT.

Warning!

To prevent injuries to the user or damage to the amplifier, read all safety instructions written 
on this manual;

If  you  are  insecure  about  the  installation  of  this  equipment,  get  in  touch  with  our  tech 
support or with a professional specialized in car audio/vessel audio installation;

Before  proceeding  with  the  installation  of  any  electric  equipment  on  your  vehicle/vessel, 
unplug the negative (-) terminal of the battery to avoid  fires, injuries or damages;

Use your sound system safely. The continuous exposure to sound pressures over 85dB 
may cause irreversible hearing damage;

This  equipment  is  for  use  in  DC  voltage  batteries  between  12.6  and  14.4  volts.  Before 
installing the equipment, check voltage of the batteries;

Choose a ventilated place to install the amplifier ;

Mount  the  amplifier  in  a  secure  way.  Avoid  mounting  it  on  metallic  parts  of  the 
vehicle/vessel, because it may cause ground looping (noise);

Make  sure  that  the  location  chosen  for  the  amplifier  installation  does  not  effect  the 
operation of the vehicle/vessel;

Please select a dry location to mount your amplifier. The products are designed to
operate in humid environments but the  direct contact with water can damage the amplifier.

When passing cables through metallic walls, use rubber O-rings to avoid cable cutting and 
short-circuits. 

Clean the amplifier periodically with brush or dry cloth to assure the thermal efficiency of 
the heatsink.

This product may reach temperatures over 60°C/140°F. Make sure it is cold before touching 
it;

Be careful when making holes in the vehicle/vessel. Make sure you are not making holes in 
the fuel tank, brake lines, boat hull  or electrical cables of the vehicle/vessel;

Make sure the cables are properly secured throughout the installation;

Wear  gloves,  safety  glasses  and  and  all  necessary  PPE  during  the  installation  of 
SounDigital amplifiers.
