My subwoofer turns on with a thump almost everytime I turn on our ceiling fan. It's set in the rear of our living room (best place I could find for it). I ran the cable up to the ceiling, across the attic, and down to the controller. My initial suspicion was that my cable crossed one of the wires that provide power to the fan. I checked, and it does cross some wires but they do not make physical contact with eachother. I'm assuming this problem could damage the sub so, if anyone can give me some ideas to prevent it from turning on, please let me know. I don't know if this has anything to do with it but I've also noticed that if I move the coax cable into a specific angle at the connection with the controller, the sub turns on and rattles the whole house until I adjust the cable back. I've checked the connections and they seem to be fine. Would this mean I have a bad controller, or the connection to controller is bad, or both?
