    My father bought this home theater package, and it sounds really good, but the sub isn't working properly. it powers on fine. when the gain is turned up, all i get is a 60 cycle hum. we have it plugged in properly to the passive sub out on the back of the amplifier. and, just plugging power into it and touching the jack produces the same 60 cycle hum. the sub itself doesn't have a ground lift switch on it, and it is acting like something from a grounding standpoint isn't connected on the inside or is loose enough to cause problems.

    we will probably have to at least take the sub back to where it was bought, but i wanted to make sure that i had all of my thoughts and troubleshooting straight. the only thing that i haven't done is bring it to my house and hook it into my surround system to see if i get the same results.

    any other thoughts out there?

    Did you tell the receiver/amplifier that there is a subwoofer in the system? And did you set the speakers to "small"? Make sure all your cables are good and intact. If it still doesn't work i guess you gotta take it back.
