I have heard quite a few people talking about their Z680's here, I have been constantly having this problem here, I got to know does anyone else's amp on the back of sub constantly rattle when listening to music? I cant seem to fix it for anything and it definitely has to be the amp and not the surrounding things.. It just doesn't make sense, was it loose connections out of the box? Did they do a poor job putting it together? I am really pissed at this I mean brand new speakers, can anyone help me ?
thx
