Well me and my gf decided that we're gonna get another vehicle from our 2004 Ford Freestar family van. It's gonna be a 2003 Cavalier 5-speed. We've gone out and test drove a couple of them and we're thinking that this is gonna be the one. As far as system wise the front doors are 4x6? according to Crutchfield. Is this right? But the rears are 6x9's. I'm gonna do a DB series and need some suggestions. What do you all think about something custom? Also 5 1/4 component's can go in the kick panels. Would this be good and then put the 4x6 in the doors? Or leave them out completely and just put in the kick panels? Am I right just going with the 6x9's or should I put 6 1/2 component's in? I also want some kind of custom sub enclosure cause I still wanna be able to keep my spare tire in. Can somebody give me some suggestions?
