Im looking to get new front and rear speakers in my evo 8. I want infinity kappas.

Should i get the kappa 6.5" 3-ways all around? Or jsut the 3 ways up front and coaxels in the back?

any help is appreciated im getting them for christmas

 

Are you talking about 3-way components or 3-way coaxials? There are 2,3, and 4-way coaxial speakers. More does not mean better when considering coaxials.
