a gauge wire or the terminals connecting the amplifier power
to the electrical system are dirty or corroded. The ESP status LED
also will give one short flash followed by a long pause for under-
voltage. This cycle will repeat.
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.
the headunit when jump-starting the car. The ESP Status LED
will also flash with one long flash followed by a long pause
(approximately 8-10 seconds).
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 Protection/ESP Status indicator by a
3 short flash sequence that repeats every 8-10 seconds.
a description of reasons the amplifier could engage the Thermal
Circuit.
Speaker loads lower than the amplifiers minimum 1 Ω 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 1Ω load input. This may also result in the overcurrent
protection mode being engaged.
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 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
Turn off area, the main car cabin may cool down before the rest of the
car has dropped appreciably. Also, if the amplifier is near the
thermal protection temperature point, turning it on and off via
the remote line can result in it entering thermal protection.

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.
