Question My Pickering subwoofer has it's amp buzzing - IMPORTANT

[SamToz]

Hey ! I have this active Pickering subwoofer that buzzs loudly when I turn it on, regardless if I play some music or not. That happened when I was fiddling around in the amp's motherboard and made an false manoeuver. The motherboard + capacitors seem fine visually, when that happened it made an electrical noise mixed with a hum, and I almost instantly unplugged the amp, when I plugged it back in, it made an loud noise (approx 120hz) and no other sound came from the amp. Someone knows how can I fix that ? Maybe by replacing the capacitors ?

I'm no expert, but make sure there are no breaks in the cable or any other metal touching the cable. It sounds like there may be a short somewhere with the cable the first place to look.

120hz sounds like a power supply issue. Try the sub on another plug, maybe with a good power strip of UPS on it.

It's possible that the issue you are experiencing with your subwoofer may be caused by a problem with the amplifier's motherboard or capacitors. It's also possible that there may be an issue with the subwoofer itself.
