I have an Alpine CDM-7874(50Wx4) head unit in my '99 Sport with a Polk EX-368 speaker in each door. They sound really great. The speakers take around 40 hours(per Polk technical support) to break in and sound their best. I've found this to be true. I'd recommend Crutchfield since they send you wiring harnesses which will plug directly in to you factory harnesses. On their web site, they will show you what fits in any car. It's pretty cool. They also send illustrated instructions and have lifetime technical support for everything. I have a referral number which will get you $20 off your first purchase. I installed the four speakers in about an hour and a half. cThomp21's post has the Crutchfield instructions linked in his post.
