      If the airbag light is on after working on your vehicle with the Alpine Speaker System, it may be because the battery wasn't disconnected during the work. Disconnect the battery and reconnect it after 5 minutes. If this doesn't solve the problem, take the vehicle to a Jeep dealer.

      Christopher MartinezAug 8, 2025
      If the volume is too loud with an aftermarket headunit using your Alpine Speaker System, it might be due to the speaker level out being connected at the T-Harness. Ensure that the low level RCA adapters are used in the aftermarket headunit system, referring to the corresponding wiring diagram. Also, check if the amplifier's gain control has been properly adjusted, referring to the system diagram.

    Why does my Alpine PSS-23WRA subwoofer sound very low?
    • C
      Casey GilbertAug 13, 2025
      If the subwoofer sounds very low with your Alpine Speaker System, the gain level may be set too low. Adjust the level to the recommended setting, referring to the wiring diagram. Also, the audio phase might be reversed, so ensure that the PHASE is set to 0.

      Steven HarrisonAug 18, 2025
      If your Alpine Speaker System only turns on when the radio source is selected, it could be that the aftermarket power antenna wire is connected to the amp. Connect the Remote Turn-On wire (Blue/ White) to the Blue wire on the amplifier harness.
