i got a hella deal on my mlk2's, no way i would be able to afford a $2500 set of speakers, but they are the best sounding speakers ive had the chance to mess with, prolly one of my fav upgrades, bad thing is most people dont know or could care less about good sound
but you have to realize there is more to it than just getting nice speakers and putting them in, without a good EQ and Time alignment it would be a waste, if i were you i would look into a processor or new HU, the new kenwood excelon units have a ton of sq stuff in them, T/a, pretty good eq, etc
