speakers: polk

ok, i have been looking at speakers at awhile for the gp....i was online today and i looking at polk's 6x9s (Polk Audio db 690) and 5 1/4" (Polk Audio db 525) the head unit will be Pioneer DEH-P4600MP CD/MP3/WMA Receiver. i havent decided on sub amp yet but im thinking jbl 1200.1 if i can find it for a good price. what do you think about the polk?

I like the Alpine head units personaly, and their amps.

As far as polk, I don't think I've heard anything bad about them.

i wouldnt mind alpine but there really expensive and this one only puts out 16watts per channel which i think is really low
