I am about to change everything in my car I just wanted you guys opinion on what I should get I was thinking about getting:

Head Unit: Alpine CDA7893
Front: Infinity Kappa 462.5cfp 4x6 plates
Rear: I don't know if I should get 6.5 Infinity components or 6x9's
what do you think would be better?

693.5i vs 60.5cs

 

i kave Kappa 6x9s the old green ones, i like them a lot, can be a little bright, but sound very good, and i have a crap amp pushing those and my boston acoustics up front, sounded better off my eclipse head unit power but after i ran all the wiring didn't feel like undoing it, so just going to replace the amp. i say get the 6x9 i prefer them to the 6 inchers, at least in the kappa brand
