The plain simple fact is that it takes power to deliver power.
Keep the amplifier out of the engine compartment and other locations that may cause excessive heat or moisture. Make sure your ground point is at the frame or a chassis point with direct frame contact. Note: the "quiet metal" on many new cars make body panels very bad ground points, so always try to use the frame.

TROUBLE SHOOTING GUIDE This power amplifier has protection features to prevent most forms of damage. If the unit senses excessive heat, short circuited speakers or overload, the protection indicators will be lit and the system will be turned off. Prior to checking the wiring for any fault, you should turn all level controls down and turn off power. If the amplifier shuts down due to excessive heat, the protection indicators will not be lit: simply allow the amplifier to cool down.
