What do y'all think of Infinity Kappa 60.9cs for a 2007 MCS Coupe with Standard Boost CD radio. Just want an opinion, although I realize everyone's is different. Will they fit. Crutchfield says it will. I will replace the 3.5 top door speakers with the tweeters in the Infinity Kappa 60.9cs set. Will use the template found on the forum. I will do the channel swap as well. I will NOT be using any amp, just the existing Head Unit. I like clean non muddy sound with good treble. Just want to be finally certain before drop the cash.

Later I may opt to swap out the rear 6X9s, but not yet.
