Ok I have a Ford Explorer so all that will fit is 5 1/4's. I want to have very good sound, and I dont need alot of bass b.c thats why I have subs. I'm trying to stay under 800 for one set of comps for the front and coax's for the back, each being run off an amp. I know most people say that you should just keep stock in the back but since they are blown thats not an option. Basically I've been looking at MB Quart QSC, Boston Acoustics Pro50, and Diamond Audio S500s, but I'm open to other suggestions.
