    Default RM6750 sub random humming issues

    I just bought the RM6750 speaker set and the sub is humming. When the receiver is off the sub will hum for 5 to 10 seconds then stop. About a minute later it will hum again for 5 to 10 seconds again. This goes on and on. I've tried two different cables to no avail. Any ideas?

    Thanks
    :)

    12' RCA cable from receiver to the sub

    Welcome to the forum
    Try plugging the sub's power chord into the receiver's aux. power outlets(IF it has any)
    I had a sort of similar problem with my sub-it would make a popping noise when I shut off the ceiling fan, even though the rcvr was off.
    It was on its own outlet, seperate from the rest off the system, which was powered thru a surge protector.
    I've sinced moved it to the rcvr's aux. outlets and it just makes a slightly muffled
    noise now when I power down the rcvr.
    Good luck
    I refuse to argue with idiots, because people can't tell the DIFFERENCE!
