Hum, or 60 hertz ground loop problems are common with sub's. The problem arises when you have two grounds, one threw your interconnect to the preamp and one threw your power cord, which creates different ground potential's .Try a chassis ground from your sub to the preamp. Take a screw out of both chassis to accomplish this if necessary. Audioquest has sub interconnects with built in ground lugs.
