No matter what you put in, i would HIGHLY recommend getting a processor for it. I re-did my whole audio package in my base V6. JL speakers all around, amp, processor, and sub and it was amazing the difference. My opinion you will only get so far without processing. Also processing on my front speakers gave me a "L C R" field and can also "help" get something out of the back speakers. But since where they are mounted, there isn't much they can do besides "fill" in the back.
