I have a Clarion DXZ745MP which I like a lot but it leaves a lot to be desired as far as tone shaping/eq/crossovers. It doesn't have a hpf built in so I have to use my amp (an ed nine.2) hpf which I don't like too much because I can't tell where it's set to acurately. Anyway, I was thinking of selling it to get a higher end clarion or an Alpine but maybe an seperate digital crossover/eq would work out for me? I like the head unit since I can change the colors easy, I know how to use all the features and it sounds good. Any comments?
