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.

ssOvervoltage: 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. The ESP/Protection Status LED will also flash with 1 long flash followed by a long pause

(approximately 8-10 seconds).

ssThermal: 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.

ssSpeaker 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.

ssThe 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.

ssThe 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 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.
