Powered subwoofer pulsing sounds .PSW110

My subwoofer has a pulsating sound, I have tryed everything including unplugged it from the amp and plugged it into a separate power source and it still has post a popping noise. I have cut all the power off in the house and ran one circuit at a time and it still has a popping noise.
The sub is only 3years old. It is a great sub with excellent base response until now.

    Hello,
    In all likelihood there's a problem with the bass amplifier. Do you live in the U.S.?

  • Yes I do !
  • Maybe you're listening to rap. Sometimes that'll cause an irritating pulsing sound.
