to the electrical system are dirty or corroded. The ESP/Protection
status LED also will give 1 short flash followed by a long pause for
undervoltage. This cycle will repeat.
Overvoltage: Vehicle charging system is supplying too much
s
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. The ESP/Protection Status
LED will also flash with 1 long flash followed by a long pause
(approximately 8-10 seconds).
s Thermal: If the amplifier heat sink temperature is too high to
continue safe operation, it will also enter protection mode. The
ESP/Protection status LED will give 3 short flashes followed by a
long pause. This cycle will then repeat.
Thermal LED: This LED lights up red if the amplifier overheats. An
amplifier enters thermal protection due to conditions that might
otherwise result in damage to the amplifier. The thermal protection
mode is also indicated on the ESP/Protection Status indicator LED
by a 3 short flash sequence that repeats every 8-10 seconds. Below
is a description of reasons the amplifier could engage the Thermal
Circuit.
s Speaker loads lower than the amplifiers minimum 2Ω 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 a load greater than the amplifiers
minimum 2Ω load input. This may also result in the overcurrent
protection mode being engaged.
s 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
s
extremely hot. This can occur in extreme climatic conditions. 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.

NOTE: Please note that the top cover plate is designed to be reversible.
The LED colors will therefore appear to reverse their order relative to
the diagram labeling if the cover is reversed when reattached, for
example; the green LED (power) closest to the Orion logo in the
diagram will be the furthest from the logo with the cover reversed.
Also, if the amplifier is near the
