nOsSvTcOnToUr: I've got Infinity Kappa 693.1i 6x9's up front, Pioneer TS-A6865 6x8's in back. Fitting the 6x9's was just a matter of drilling new screw holes. The Pioneers aren't too bad, but there are definitely better options available.
abwamo: Your distortion problems with the Pioneers were probably due to feeding them too much power. They're only rated 50W RMS.
