Applicable Products and Categories of This Article

While the car stereo system is being used, the inside of the device heats up. This does not usually indicate a malfunction. However, if the device gets too hot when touching it, check the following:

The following are reasons why the back of the car stereo may become too hot to touch during normal operation:

  • The audio system may not be installed properly.
  • The speaker wires have been combined rather than only having two wires connected for each speaker.

IMPORTANT: It is recommended that the speaker wires and installation of the car stereo be checked by a qualified professional installer.

If the issue is still unresolved after a qualified installer has checked the system, service may be required.
