So I've noticed an increase in vibrations and rattles while playing music since the installation of a DICE system into my MCS. I have one coming from somewhere in back that seems to be associated with low-frequency notes - I'm not to concerned with that one since it's probably just something loose vibrating around somewhere. The one that does bother me it a raspy static-type noise from the tweeters that is coloring the sound at certain frequencies. Based on what I've seen around here, I suspect either something is loose in the door, or possibly the tweet is blown... But I'm not sure why it would have surfaced in relation to the DICE installation. Coincidence maybe?

I seem to recall reading that people were able to have various blown speakers replaced under warranty - is this true? And how about aftermarket - Do you could I swap in a ~2ohm tweeter without seriously upsetting the factory tuning?
