05 Mustang front stage?

[nhra427]

I have a 05 Mustang without the shaker system. Has anyone done a system in one of these? I have the koda 6s and Aura tweets to install. I see they have the 5x7s high in the door and with a shaker system they have an 8 in the bottom of the door. Was thinking of a passive 3-way but dont know if I should start over or just add some 7s or 8s in the bottom and mount the Kodas where the 5x7s are. Has anyone done a dayton RS 3-way system?
