Sorry for the confusion, but I was talking about increasing the sub trim. I found the LFE option as well and left that at its default (0, and it only goes to negative values). I currently have the sub trim at max (+10) and the sub volume at about 9 oClock. It works somewhat better, but I still have the sub cut out every now and then at lower volumes. Is there any way the cable could be the problem? I'm using a brand new 25' RG-6/U 18AWG CL2 cable from monoprice. There's no hiss or anything, so I don't believe the cable is receiving excessive amounts of noise. I have a cable from my old sub, but its about 2' too short to just hook up to try out (found that out yesterday). I may have to move the sub out slightly to see if the other cable solves the problem.
