I had the 6966's, I touched on them some in my build thread (link in sig)... summary - better than stock, but there's better out there. I've since upgraded all around adding higher end speakers, couple amps, 12" sub in fox box, DSP, etc but if I were doing just a simple speaker upgrade, I would look at the RAM-specific Kicker setups, or the Kicker setup @Graygoose linked above.
