hendrixhc 10,921 Posted January 30, 2015 So i am going to be fiddling round with the head unit installation this weekend and one of the ideas i have had is to modify the heater box directly behind where the head unit sits. Bare in mind it is a double din unit so it is quite large. I was think of reshaping the heater box , where the single screw goes in, and moulding it back about an inch to get the unit sitting flusher with the fascia. Theres no moving parts there only airflow from what i can see. footwell vents? Does any one see any issues with this? Share this post Link to post Share on other sites
