Any help on removing the buzz.
Sounds like you have a ground loop there. Does your sub have grounded power connection? If so, you can try lifting that (use one of the cheater 3 to 2 wire adapters) and see if that removes the hum. Also, you can try using a cable to the sub that lifts the shield (ground) at the sub end (these can usually be recognized by arrows printed on the wire that are to be oriented to point from source device to destination device).
