ok I'm no expert here so I'll explain it the best I can. I have a D-box David 302 12-inch sub with powered amp running off a TEAC receiver. I have two setup positions for the Sub. The first one is close to the receiver so I use a direct cable from the receiver to the Sub (probably 12 feet long.) The second, and the one I am using now) moves the sub farther from the receiver and therefore needs a longer cable. I use a female/male connector to join the two cables. When the two cables are connected, the sub 'sometimes' develops a problem where it starts to rumble for no apparent reason. It's very loud. I have to run over and shut it down. IT happened again tonight when I was using the playstation. Shut it down, waited awhile plugged it back in, no problem. I have to think it has something to do with the connection. I have taped the connection together so it does not come loose. Hope that helps.
