MTX 9500s rule. My one 9512 in a snailshell to a 1501d seemed much louder and cleaner to the ear in all frequencies compared to a 13W7 I heard on 2 1000/1's. This guy was running his system directly into his cabin of his car and mine is in the cabin (ford explorer). 9500s get nasty, just get the right box. If I were you and you had the money, get 2 9512's or 2 9510s hooked up to about 2000-3000 watts in a nolteaudio.com doubleshot, that would nearly rip your car in half though. My single 9500 is destroying my car as my rear seatbelts no longer work (stay locked forever now) and my locks aren't working right. It's always fun showing off my system though, NOBODY, i mean NOBODY believes it's one 12 back there until I show them.
