I have a JBL SUB160 self powered subwoofer that is squealing or whistling, even when the receiver is muted, or the cable is disconnected. I've had to turn it off in order to get it to stop. It will also ocassionally send out a loud thump like extreme thunder. I am using the LFE input. It comes and goes. Not sure if it's the Onboard amp or the speaker Unit is 4 years old


ANy suggestions would be appreciated.

PROBLEM SOLVED!!!!

THANKS to NorCalJason for the Solution.

Thanks for the suggestion. I would have never thought of it.


Life is good again!


Thanks,

Jeff

That sounds like a defective amp.

Do you have a farmer that lives next door calling his hogs. Maybe the hog ran into the side of the metal pole barn...just a thought. Couldn't resist

Don't find the manual, but if it has low level (line level) inputs, try one of them. It will at least tell if the LFE input is good or bad. Other than that, bad amp.

I’m not buying this, sounds like load of hocus-pocus.

Any pig-squealing city boys in the house?
