How to fix Logitech z623 subwoofer bass distortion issue

I upload this video to help you guys who face the same problem of this subwoofer Logitech z623... The problem was distortion in bass when we volume up.... you know I was disappointed by that problem bt finally found the main issue.. which was the power capacitor (you ll see the black capacitor in this video) where it got disconnected from the circuit. it's simple to fixed u just need to soldering it little thicker and you are done... Now my sub logi z623 is working fine with full bass with full volume ..if it help you guys pliz like the video. Thanks for watching and reading.
