Subwoofer hum - Is it my cable?

So I have a subwoofer hum when i pause a bluray, or i turn off my amplifier etc.


I unplugged everything from my surge/powerbar and the hum still occurred. I tried different outlets etc same hum.


I then took the sub into a totally different room, plugged the sub into the wall outlet, turned it on.. then when i plugged in my subwoofer cable into the sub and left the other end unplugged/free, i got the hum. Also, if i press my thumb against the male end of the opposite side of the sub cable (the side not plugged into my sub) the hum gets louder.


Any ideas?
