ok this is a relativly easy one- you are having a problem with ground loop isolation --ie:the power that your reciever is getting from the wall is slightly varied from the power that your sub is getting, there are two ways about this.
1.You can use a surge protector and plug both the reciever and the sub into it, or if that doesnt solve the problem,
2. you can run a lenth of wire from the outside part of the RCA on the sub to a screw on the back of the reciever to try to create a consistant ground between the two components
i had this problem with my theater system only because i am using a computer power supply and an bazooka bass tube out of a car -i ended up grounding the RCA to the computer power supply to correct the problem.

The humming is there all the time, you just can't hear it when the volume gets is loud
You have replaced the cable, and it's no different?

Therefore, the only place the problem can be, is your a/v amplifier or receiver. You need to check out all the connections, joints and solders for a poor connection.

This is not irony. This is either a bad cable or a bad soldier point inside the receiver. Let's hope it's the cable.

sure, it may. it does no longer make as a lot vibration and damn, you're able to in trouble-free terms experience the bass. it is likewise a very good theory to vent the container so as that warm air can get away from the container and not reason your sub to overheat. wish this facilitates (:

It sounds like a grounding fault or your cables are not RF shielded so they are picking up mains humm, have you got the audio feeds near any wall warts?
