Just an update on this. I havent been able to resolve the issue and need a longer power cord in order to get to another plug that is not connected to the same as the stereo.
I just found another cord. The problem is when Axiom updated the sub they changed the amplifier. I was able to get the updated sub amp and it no longer has an RCA type input but replaced with a 1/4. That is loose and causing the humming. I am just going to replace the sub with another brand.
