My subwoofer (a energy esw8) won't auto off for some reason. It does auto off as soon as I unplug the audio cable, so I think the problem is on the cable or receiver. The cable must be carrying some noise even though I cannot hear anything from the sub.


Now, what kind of cable should I get? I am only using a regular red-white RCA cable. Would one of these works?

It's not necessarily a fault of the cable or the receiver. The most likely cause is a bit of ground loop. Those can be hard to track down. Might happen if the sub is on a different electrical circuit, could easily happen if there is something else hooked up to your system that has it's own separate ground, like a cable box, antenna, etc.
