KG, sounds like a heck of a deal! I think I'm going to stick with the Polk speakers that came with the tower though. Probably keep with Polk inside boat as well. What kind of Jl amps are you trying to sell off, and would you separate from the Krypts?
I'm looking for enough thump out of the sub that I can at least hear some low's while underway, I had an older 10" JL sub in the enclosed bow of my American Skier but it wasn't powerful enough to hear once planed out.
