I think bill @ monster tower ran that setup for a while? Don't know what amp, but he had 2 pair of the kb600. My guess is you'll be able to hear the mucis, but proabbly not understand much of it. You'll her all the highs and almost no mids, on top of that you'll blast everyone in the boat with ear piercing highs.
Mike is right, if want want to meet the above mentioned criteria, start savin and get the NVS or Skylon systems
The only complaint I'llever have w/ the NVS is if someone is sitting on the back is to turn it down a tad, never turn the treble down.
