The Kickers don't have as good power handling as the Pioneers. I would still go with the Pioneers. As for door speakers, take these into consideration as well.
Pioneer TS-A1304C (TSA1304C) 5.25" 2-Way Component Speaker System
Being components they will sound better than the 3-ways. That's what I would do.
I'm kinda a Pioneer/Polk Audio junky. I'll let others chime in about Kickers. I don't have much experience with the brand.
Combined with your head unit, the amp will be more than enough power for the door and deck speakers. I don't know if you're crazy about bass, but with that amp and those 6X9's I don't think you'll be wanting a sub too much. At least for a while.. Haha.
