You have whats called a ground loop. As far as no punch, make sure crossover on the sub all the way up (120) and you're volume knob at 12o"clock position and you're phase set to 0. Make sure you're speakers are set to small. Here is some info on ground loops. http://forum.blu-ray.com/showthread.php?t=97963

I will bet you if you disconnect you're coax going to you're cable box input the hum will be gone.
