its not volume like volume of the radio. its like volume the amount of space in the car. so im guessing the sunroof takes up more space and forces the headliner to be down a little more
nick ... =)) i know what volume means man ... tx though .. but i don`t think so .. cuz u have more head space where the sunroof is ... and if u put a car with and without a sunroof besides .. it`s the same height ...
