I have had numerous different speakers in my cars (all G-bodies) and I must say, for the FRONT speakers, the 3.5" Infinity Kappa is about THE BEST speaker for the money, AND you can install in the factory location. I don't think the Regal has anymore clearance than my Cutlass, so you might have to do what I did, and install them from the bottom, and NOT drop them in from the top. The Coaxial tweeter sits too tall for the cover to go on top.
These speakers retail for about $100/pair, but with some shopping around, you can pick them up for $60 or so.
