Initially, let's try check and review the basics. Proposed preliminary tries (if have not been done):

  • • check / replace the 15A fuse;
  • • test for consistent battery +12V at the (+)BATT terminal;
  • • ensure that the (-)GND is tied to a good vehicle body/frame ground;
  • • determine if there is a switched +12V at the REM terminal.

All others would be internal to the subwoofer.
