You're not "jumping" the basslink off the amp are you or vise versa?
I'm with nicholoff on this one. I believe the power is grounding out somewhere in the wiring. That may be what's causing the noise. Also, check all your speaker wire leads. Some may have come apart or are being pinched. Happened to me not too long ago. The wiring to one of my tweeters came loose and it started doing the same thing you are talking about. If that's the case, you need to get it fixed asap. You don't want it grounding out near anything that is flammable.
