Reverse Polarity:

Any instance when the battery polarity or wires

from the battery to the amplifier are reversed .

Thermal LED: this LeD lights up red if the amplifier overheats . An
amplifier can thermal many different ways and below is a description
of reasons the amplifier could engage the thermal Circuit .

speaker loads lower than the amplifiers minimum impedance

load will cause the amplifier to draw more current and may
result in overheating . this can be avoided by using speakers or
wiring methods that result in an impedance load greater than the
amplifiers minimum impedance load capability .
the amplifier can also overheat if it is not receiving proper

ventilation, when mounting a amplifier make sure it has room for
air to circulate and keep it cool . Amplifiers will get hot because
they produce energy and care and consideration should be taken
into account when installing any amplifier .
the temperature inside the car where the amplifier is mounted

is extremely hot . this can occur in desert climates . It is not
uncommon for temperatures inside a parked car to reach in
excess of 140°F (60°C) . If airflow is restricted to the mounting
area, the main car cabin may cool down before the rest of the car
has dropped appreciably .
