• Overvoltage: Vehicle charging system is supplying too much
voltage or over the amplifiers rated DC input. Usually this occurs
when there is a problem with the electrical system. Turn off the
headunit when jump-starting the car.
• 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 load will ause
the amplifier to draw more current and may result in overheat-
ing. This can be avoided by using speakers or wiring methods that
result in an Ω load greater than the amplifiers minimum Ω load
input.
• The amplifier can also overheat if it is not receiving proper ventila
tion, 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 uncom-
mon 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.
