2001 Surburban

I am about to receive a 2001 suburban from my father and i am wanting to put a nice stereo in it.  My problem is that I want it to be a nice system that is not to flashy, but sounds awesome.  I have always had a very bassy system in my other cars, but I am going for the clean sound now.  Another thing is that I don't care about the amount of bass, I want it to all balance with each other.  I listen to all kinds of music, but mostly rock and country, not so much rap but i still want to be able to listen to it and it sound real nice.  I have a good head unit, and I would like to use a pair of kicker L7's 10"  i am not sure if this is a good idea.  I also would like to put a pair of kicker free-air 6 3/4 in the doors up front with a 4" component set.  And then a 6 1/2 in the back doors.  I need help with how to wire and which brand of speakers and amps to use.  I don't know if a 4channel amp could push all 6 of the speakers, the components the free-air and the back door speakers, and another to run the subs.  Just any help yall could give would be great.ThanksChandler Martin
