Do all sunfire subs hum and pop?


I have a sunfire super junior that almost constantly hums and on occassion makes odd pop or ckicking sounds. I have witnessed anothere that had the same hum. Its sounds like the same hum that comes from my cieling fans or low voltage lighting. Obvious I suspect the power. I've tried the Monster HTS 5000. Didnt help. Before I spend more money I thought I'd put out some feelers. Any help would be appriciated. Everything else seems to be fine except a hum bar that runs from left too right only when watching DVD's. Sorry if this is a redundant topic. Thanks for any help.

get a 3 prong female with a two prong male and then plug the sub into that adaptor which is easily available - the hum will definetly stop!
I have a sunfire MarkII and have never heard any humming. It does pop when turning itself on or off but ill deal with that for the serious bass it pushes out.
