Hi I am afraid it sounds like exactly the same problem I had, Namely the PSU(power suplly unit) is failing, This is a common fault (by reading loads of forums) I contacted KEF today about mine and they say the probably wont be able to source any more spares(due to so many having thuis problem no doubt) So I would suggest contacting the people you bought it from,Under the consumer protection act you should expect an electrical item to "Last a reasonable amount of time" .Mine is 3 years old and I do not consider this to be a long period so kick up and you should be entitled to a repair or at worst a partial refund.Look here basically the same Sub.

if it is a powered sub you should lift the ground. you can do this by adding a three prong to two prong adapter. you know, like when you go to plug something in and the cord your plugging in has three prongs and the outlet your plugging in to only has two. it doesn't have the hole for the ground so you go get a little grey adapter that has three holes on one side and two prongs or tabs on the other.if that doesn't take the hum out (actually, is keeping the hum from getting in) you have a problem with the amplifier.

im having the exact same problem thinking it was the amp i rigged up a different driver,the amp was fine.i knew the driver wasnt gone and after some looking and testing i got it down to wire mesh(i think a dust sheild,something)inside which was slightly rubbing on the coil,it worked fine loud when it was warm but cold there was bursts of bad feed back noises.
