Did this today for a customer at work. Customer has an 05 Caravan and wants an overhead monitor installed. Says she has been everywhere locally and most several places said they cannot do it due to the fact that the headliner has a pretty gnarly little hump/curve right where the customer wanted the overhead mounted. Overhead being used is an Alpine PKG-RSE2. Customer said one shop tried to freehand cut the plastice shroud that came with the monitor to match the headliner but it was not to her liking so she came to me. Now on to the pics.
pic, of the headliner right after i taped it off. You can see the curve/hump in the center thats where the monitor is going
This is what the monitor will be mounted to. It is cut to the exact match of the screen
Our piece of wood mounted to the headliner via a steel brace running under the headliner
Shot from the otherside so you can see the space that needs filling
made a sleeve so that we can build up the duraglass
