I agree with Phase Correct about the recording of rock. I have Dunlavy athenas fed by VTL at home and i have to admit a lot of my rock cds sound a lot better in the car. You might want to look at EV pro gear. Tons of thump, decent transparency when you take some time to set them up...generally very good speakers but not as revealing as high end audio. as an added benifit the next greatest band in the world that just ran out of time probably has them for sale pretty cheap. S-15s are a good 3 way that you should be able to find for less than a grand in very good shape. They have a higher end version that sounds great but is more money..still not 5k though. WAF for either of them, however, is non existant.
