Hey, I've got some sony Xplod 6x9's and although they can handle a pretty high volume..the highs/midranges are pretty muddy. I have infinity kappas [3.5"] in my dash which have amazing highs. Whats a good 6x9" speaker that will have real crisp mid/HIGHS. I have a sub and will be running these speakers off of the headunit. Thanks -Alec H.
