Car amplifier

4 Channel, 900W Peak CMQ405/00


The light is red on my Philips in-car audio device

The amplifier has a build-in protection circuit to protect the transistors and speakers in following conditions:

  • The amplifier is overheated
  • A DC current is generated in speakers
  • The battery voltage is too low or too high
  • The speaker terminals are short circuited

When the protector indicator lights up in red, the amplifier shuts down automatically. In this case please:

  • Take out the disc or tape and turn off the car audio
  • Check the cause of the malfunction
  • If the amplifier is overheated, let it cool down
