when I turn up my 6x9s they rattle...not that they are blown but all the junk behiond them rattle..how Can I fix it?? thanx

i like your nickname
you could try some foam or dynamat to stop the rattles

What usually is rattling behind the 6x9s is the plastic vent looking piece that's next to the speakers when you open the door. I just took mine off for now, untill I get some damping foam or something to put on there to keep it from rattling.
