    Have you tried reversing the arrows? (think outside the box) [​IMG]
    Well since the subwoofer hums whether it's on or off, have you checked if it hums when connected to the receiver?
    If it still hums then maybe try plugging it into another rooms electric socket and see if it still hums. (Find out if the noise is power related)

    Sounds like a ground loop. Try a three prong to two prong cheater plug and if the hum goes away you have a ground loop probally caused by a cable tv or dbs system connected to your tv. This is only a temporary fix and you should purchase a ground loop isolator. Hope this solves your problem[​IMG]

    well actually the cable goes right under our cable box power thing (to send more power through the cable)
    could it be the problem going over power wires etc ?
    if so how do i fix it

    Did you try the 3 to 2 prong? if so did the hum go away?

    With a three to two prong cheater plug you are elimanating the ground from the unit. with a ground loop isolater it breaks the ground loop by using a transformer to completely isolate the singal from the ground connection. Jason-Pro how is your sub connected to your reciever? If you are using a rca type connection from your reciever to your sub and your reciever is plugged into your outlet w/ a three prong connection you will be alright using the 3 to 2 cheater plug as for the rca interconect from your sub to your reciever will act as the ground. If you want to go the ground loop isolater route, they cost around $100 and any stereo store should have them or you can buy online at places like audio advisor.
