OK whenever im bumping my two 12" L7's( they are powered by a kx12001), the subs dont move in and out very much... those of you with L7's, do your subs really wang in and out a lot when your bumping them? i usualy turn my head unit volume to like 25/35 and it starts to hit pretty good, i want it to be louder, im just worried to put it up to like 30 or some **** because i dont wanna blow my subs.
