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 automotive DC voltage batteries between 12.6 and 
14.4 volts. Before installing the equipment, check voltage of the batteries;

Do not install the amplifier in places exposed to water, dirt or humidity;

Choose  a  ventilated  place  to  install  the  amplifier  and  avoid  blocking  the  side 
ventilation windows;

vehicle, 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;

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;
