What causes a amp to go into protect mode?
Overheating. Some amps go into protect mode if they get too hot, which can prevent a permanent failure. The common cause of overheating is a lack of airflow. If the amp is located underneath the seats, or in another confined space, that may cause it to overheat.
What does it mean when your amp light flashes?
Many times, the protection indicator will blink to indicate the reason the amp is in protect mode. If the power light blinks then goes off, the amp is either going into protect mode or there is a bad connection in the power supply wiring.
What does Protection light on amp mean?
The POWER/PROTECT light will change from green to red under the following circumstances: When the car amplifier is overheated (thermal overload). A speaker wire has short-circuited.
Why is my amp flashing red and green?
Amplifier turns off at 8v DC and turns back on when 9v DC is detected….Amplifier Status LED Colors & What they Represent.
| LED COLOR | DESCRIPTION |
|---|---|
| Green Flashing | Amplifier is powering up. |
| Green Solid | Amplifier is powered and functioning properly. |
| Red | Amplifier has reached its thermal limits. Advanced Rollback Protection engaged. |
| Amber (Yellow) | Low Impedance |
Why is my amp blinking green?
It may show that the amplifier is working correctly, or identify a problem with the amplifier, installation or audio system itself….Amplifier Status LED Colors & What they Represent.
| LED COLOR | DESCRIPTION |
|---|---|
| Green Flashing | Amplifier is powering up |
| Green Solid | Amplifier is powered and functioning properly. At least 10v DC is detected. |
What does the led mean on a JL amplifier?
All JL Audio amplifiers have built-in LED’s that signify the operational status of that amplifier. It may show that the amplifier is working correctly, or identify a problem with the amplifier, installation or audio system itself.
Why is my JL amplifier in protection mode?
This is especially true when the power supply has failed. There are a few amps (some JL Audio) that will go into protect and none of the indicators change. This happens when the voltage drops too low when the amp is being driven hard with an insufficient power supply.
What do the lights on an amp mean?
Some amplifiers have multiple protect lights. For example, some of the Sony amplifiers have lights for power, overcurrent and thermal protection. The lights are always lit when the amp powers up but are normally green. When there is a fault, the LED changes from green to amber.
What happens to the red LED on an amp?
Some (like the old Autoteks) light the green LED and red LED initially then the red LED switches off. In MANY amplifiers, the power LED will be lit but the amplifier will be completely dead internally. This is especially true when the power supply has failed.
