I did not change electric outlet, in fact I moved it back to where it was anyway.

Just tried one, same hum problem.

Try disconnecting your cable ( or sat ) connection and see if the hum goes away.

I've tried every combination of things unplugged and plugged. Amp Power cord + Amp Sub cord + Sub Power cord + Sub Cord to amp = Hum
If none of those are plugged in (or the rocker switch is off), it doens't hum, but then nothing would work.

Have you tried running the sub directly to your reciever?
Assuming you have a receiver with preamp outputs.
Sorry if I am being presumptous...just trying to help.

It happened to me once and I had eventually realized that the preout on my receiver was bad.... Also try to bypass the xover on the sub and lower the volume to minimum...see what works at this point.

Ok, I was messing around with my Amp, the only time the hum didn't hum was if the Sub Out was the only thing plugged in. If the S-Video or Coaxle digital was plugged in along with the Sub Out, it would hum. Both S-Video and digi coax have to be gone, which is pointless because I need them.

You could also try the speaker level connections?

I was messing with every single cable. I relized that both the S-Video was in the TV which touches the DVD player and the Digi Coaxle was in the DVD player. I found out that whenever I unpluged the regular coaxle cable (for cable TV) the humming stopped. I had plugged in the TV cable connection in between when I was using the sub, so why did this happen? How can a coaxle cable cause this?

It very well could have been that the connection before was not as good as what you have now thus breaking the ground from the cable connection.What you have there is a ground loop problem.

Does your sub have a ground loop screw at the back. If so, try unscrewing it to see if the noise can be lifted there, assuming it's a ground loop issue. If that does not work and you think it is a ground loop, go to www.jensentransformers.com. I purchased their sub filter and it works great. Pricey but there products are top grade.
