No laptop power supplies close to the rca cable run. You don't have it turned to the max to hear this do you?

Several SMPS for the little boxes, but the sub is well away from these. It’s a ground loop thing, just wondering if It’s ok for the jacket of the RCA to be grounded to the earth. It solves the problem and stops the hum, just don’t want to damage anything.

Short answer should have been, I don't see it as dangerous, but the Sub has no earth for a reason, if that reason is electrical safety then you might have some outlying possibilities becoming a little more dangerous.
