Sorry, re-hashing this thread. I just put these in my faring, and I couldn't be happier. Well, I could be happier if they were water proof. I'm running my HCX's, via. a Rockford Fosgate TM400x4ad. I absolutely love these speakers. I can't imagine how the Millie's must sound, if the HCX's sound this good. They are so full sounding, even at 70+. I hear every note, with near perfect clarity. And voice reproduction is crystal clear. Long story short, I'm happy!

 

I have the Hertz and Diamond amp set up on my 16 RG but I much rather prefer the Arc Audio Moto package I had on my old bike.
