I've been using the K2 for a number of years to drive my two 18" Infinite Baffle Subs. The K's are very rare in the pro world as they don't use fans for cooling. Either K is a great choice as a sub amp.
They like to be fed a higher gain pro balanced signal vs. consumer unbalanced. I had problems with the amp going into "sleep" mode with the weaker unbalanced signal, but Crown has a fix for that. If you go the K route and have to use unbalanced, PM me and I can email you the "fix".
