Stock Speaker Replacement

[98 Purple TA]

OK, I just blew on of the stock speakers in the pass door. What are a good set of speakers to replace in all of the doors and the rear passenger area. This is a vert and I only have six speaker system. I want to retain the original head unit so, don't get crazy. I really want something that is as close as a direct replacement (this means little modification) with an overall better sound field.

Pricing from mid to high is acceptable (as long as the wife does not find out)

Thanks,
