decided to watch a movie last night since i haven't set up the cable at my new place yet...
my sub is connected to the receiver by a mono rca jack. when i turn the sub on, i get a low constant rumbling, regardless of what is actually going on w/ the sound.
i unplugged the power, turned on/off, switched out rca cables and the problem is persistent. if i leave the rca plugged into the sub and remove the other end the rumbling continues when i hold the bare cable on my skin.
this system is about 6 years old but i have had NO problems w/ it before the move.
any ideas?
