Stinger Radio Kits: Low Volume or Fader Not Working

Follow these steps to troubleshoot the issue.

• Does the vehicle have a factory amplifier or subwoofer?
  • If yes, the connector/port labeled "amplified" should be used.
  • If no, the connector/port labeled "non-amplified' should be used.
  • If the wrong speaker connector/port was used, unplug the PAC module, connect the speaker connector to the correct connector/port, then plug the PAC module back in. Start the vehicle and test the radio functionality.
  • For Horizon10 & Heigh10+ integrated radio kits and a factory amplifier, if the correct speaker port was used, reset the PAC module.
    1. Start the vehicle.
    2. Navigate to Settings / Installer (top right tab) / PAC Advanced Settings / Application Info /   RadioPro.
    3. Select Factory Reset.
• For Horizon10 & Heigh10+ integrated radio kits and a factory amplifier, also inspect the Integrated Audio Settings page on the radio (Figure A). 
  • Navigate to Settings / Installer (top right tab) / PAC Advanced Settings / Integrated Audio Settings.
  • Increase Factory Amp Gain to level 5.
