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.
