How to troubleshoot Planet Audio Subwoofer with no power?
- B
  Benjamin TorresAug 17, 2025
  To troubleshoot a Planet Audio Subwoofer with no power, first, ensure it's properly grounded by checking for a clean contact point on the chassis and a secure ground connection. Then, verify there's at least 3V DC remote input on the REM terminal and at least 12V input on the +12V terminal. Check all fuses, replacing any faulty ones with the same type and rating. If the red LED is on, power the subwoofer off briefly and then on again. Finally, if using a high-level input connection, ensure the auto power on feature is activated by pressing the Auto Turn-On switch on the subwoofer.
