I've noticed most use 6.5 comps for their front stage. Is this simply a size issue? If you had room for a 8"and a 4" for mid bass and mid range would this be better?Iv'e got the room if I move the tweet to the a pillar or the dash area. I'd like some opinions on a system of this type. I'd use a single 10" sub in the back if I needed more bass.
