4 x 6’s infinity vs boston acoustics

I'm putting the final pieces togrther.....need to replace my dash 4 x 6's with somthing loud, but most importantly with premium sound quality....I want to be able to hear the crisp sounds of Snoop Dog "smacking" from cottonmouth in between rhymes and the wheezing from his smoke ridden lungs as he draws a deep breath before a long chorous.... so which would be best suited to deliver the goods ? Infinnity Refference, Kappa or Boston Acoustics 746 series 4 x 6 's ?

Boston is my choice I have had a set of 3 1/2's and a set of 4x6's I think they sound great.My wife thinks bagging a truck means you kick it in the truck nuts
