Fixing a Dead Polk Audio Subwoofer 

In this video I have a dead Polk audio PSW125 with the internal power supply and circuit board from a PSW10. I removed the circuit board and looked for any damaged components. everything looked good so I used a voltmeter to check the fuse. The fuse was blown so I replaced it with a new fuse screwed everything back together and tested the subwoofer. The subwoofer worked so just have to wait and see if the problem reoccurs. (as of three months later subwoofer is still working fine).
