I have my sa6.5cs comps and some Rockford coaxials running of a sax100.4d and for some reason I get some distortion/static that's mostly noticable in the tweeters. Its not being played loudly, just normal listening volume. Not sure how to describe it, but if you listen to the song otherside by rebelution or ten years gone by zeppelin, the beginning part sounds pretty distorted. Theyre good quality songs and its with all songs not just those, it's just easier to tell. Any ideas for a diagnosis? Maybe ground issue? Internal issue? Thanks
