Kicker, JL, Eclipse, or Boston Accoustic are what I'd suggest looking into.I gotta back Polk, at least their midrange speakers are the best I've heard.  I went to Tweeters and listened to everything they had and ended up buying the speakers with the best sound quality throughout the ranges, and they were 6.5" Polk Momo's.  Nothing there sounded better, and they had everything from Pioneer all the way to Boston Acoustics.

If you check out the 06 Kicker Catalog they will state the same thing, and any salesman who knows what he sold you should have told you that as well.  I'v been building sound systems since I was in junior high as my 1st job and fell in love with the audio world and ever since they built cars for sound competitions for myself and customers and have learned a thing or two about box setups.  I hope your atleast going to fill your sealed box full of foam or cotton for the kicker the sound its best in a sealed box.  There is a new spray foam you can get that will fill it and keep your box from rattling quite well and its only $2-3 a can.
