I was giving mine 150 rms per side bridged. i figured the amp was not good and went and baught a MB QUART amp which is giving them i think 125 per side. not bridged.What kind of power are you giving the set? I had this problem with a buddies set of Dyn 242s fed off of 2 channels from a jl 300/4 (roughly 75-90w aside). The tweeters would cut out at higher volumes. But then we bridged the 300/4 and gave each side about 150w, and the tweeters never cut out again. And the set got even louder and sounded better.
