What Components?

I finally have my dream system installed...well most of it. I currently have 2 JL13W7's running on 2 JL 1000/1 amps. Also a 450/4 JL amp running 4 kicker compoents RS series. This is what my quesiton is mostly about, I do not like how my RS series components sound and was looking to replace them with a different set. I am using a Alpine D310 touchscreen deck with a PXA-H701 signal processor. I am in need of two sets of components for front and rear doors. What would be a good set to replace my RS's. I am looking in the range of the same prices as Infinity Perfects and also will work well with the 450/4 amp. Right now that is my top choice I am looking to purchase, but was looking to see if there was anything that sounded better in that same price range, take or give a hundred. Also there are stock amplified speakers I may upgrade, currently they are all disconnected. A good center channel speaker and an 8 inch sub. The 8 inch sub is not a big need I was just looking to maybe put in two 8" subs for a nice mid range sound. Thanks

sorry forgot to include my speakers are 6.5"

would two 8's add good midbass in the rear deck? also what is a good crossover i could use if my deck crossover/signal processor is not good enough? thanksAlpine D310 HeadUnit
