Applicable Products and Categories of This Article

Follow these steps to troubleshoot a car stereo that has FADER or BALANCE volume problems.

IMPORTANT:

  • If model-specific information is needed to complete any of the steps in this solution, refer to the instructions supplied with the product. Manuals are posted on your model support page.
  • We recommended that all car stereo installations be performed by a qualified, professional installer.
  1. If you are unable to hear voice through the speakers when making a hands-free Bluetooth® wireless connection, use this article  to obtain the resolution for this issue.
  2. Before operating the system for the first time, replacing the car battery, changing the connections or adding components to your system, the car stereo receiver must be reset.
  3. Turn on the stereo system.
  4. Verify all speaker channel connections are secure.
  5. If an amplifier is installed, verify that it is connected correctly and has power.
  6. If the car stereo receiver has an audio Attenuation (ATT) feature, make sure it is turned off.
  7. Some systems offer a subwoofer (SUB) volume setting that can be edited through the menu of the car stereo. If the Sub/Rear option is set to SUB-OUT, there is no option to fade from front to rear. If applicable to your model, be sure this option is set to match your setup preference: either SUB-OUT for outputting to a subwoofer or REAR-OUT for outputting to a power amplifier.
  8. Attempt to adjust the volume.
  9. Press the MUTE button, if available.
  10. Adjust the fader or balance control.
  11. When using an auxiliary input for XM radio or a CD changer, ensure the car stereo is set to the appropriate auxiliary input.
  12. If there is sound from the FM receiver but not from an auxiliary input for XM radio or a CD changer, ensure the auxiliary device is properly connected to the car stereo.
  13. Connect the speakers to a known-working connection to verify there is not a problem with the speakers.

If the issue is still unresolved, service may be required.
