Opinions On Alpine Speakers

I've just started looking for new speakers to replace my factory ones and want to get some that have strong bass, but crisp mids and highs. I have a 2002 Bonneville and am going to need a pair of 6.5", 1", and 6x9" speakers. I was thinking going with the Alpine Type-S and get all my speakers from that line of speakers, anyone have good or bad experiences with them? Any better suggestions?
