- There is a noticeable distortion in the sound.
- There is no sound even if you have already turned on your audio system.

What can cause an amp to go into protection?
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.
How do I know if my amp is in protect mode?
Not all amps have a protection mode indicator. Some simply shut down and the power light will not illuminate when 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.

Why does my amp keep turning off?
There are several different reasons that an amplifier will get hot and shut down. Four of the most common are: Blown/grounded speaker(s), poor power and/or ground connections, too low an impedance (load), or Gain/Punch Bass control settings too high.
Why does my amp pop when I turn it off?
Typically a turn off pop is caused either by a grounding issue, or just for the simple fact that the amp needs to turn off before all the other equipment. This would allow the unit to stay on a few seconds more, which should give enough time to the amp to turn off before the other equipment.
What causes Protection light on amp?
In some cases, a loose or shorted wire causes an amp to go into protect mode to prevent a more serious problem from occurring.

What to do if your car amplifier is hot?
If the car amplifier is very warm or hot to the touch due to hours of playing, allow it to cool down. Remove any connected equipment to the amplifier and then only connect the power and ground wires, then check the lamp.
Can a car amplifier be mounted on metal?
Remember that an amplifier should only be connected to the vehicle through the power and ground terminals. Mounting the amplifier to the metal of the vehicle, including putting the mounting screws into metal, can cause problems for your amplifier. Always mount the amplifier to a non-conductive surface.
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.
