Sorry if this is the wrong forum, but the issue stems from my recent home theater construction. I ran a sub cable from my gear - through the wall - to a box behind my seating area. The cable was premanufactured low grade Monster. It runs perpendicular to a couple of power runs so I didn't think that it would be a problem. Like an idiot, I didn't test it. Now the wall is drywalled up and I can't seem to get it to budge when I pull on it, so no using it as a fish. Do I have any options left or should I just consider it useless now??? Plugged in, it doesn't hum until I connect the rca cable. Help please, thanks.
