Does anyone have experience making a custom face plate / mounting. I am trying to install the empeg with a 2nd head unit in a 2002 civic.

The opening it plenty big enough for two din sized units but no one makes a face plate that will work with the empeg. Metra makes a double din one but it is set up for rear mount where the head unit is mounted in the dash and the face plate slips over the from with no trim ring.

I tried to modify one of them by cutting the hole in the lower spot big enough for the empeg sled to fit through but the problem was the dash is curved to about 1/2 an inch of the bottom of the epmeg sled shows.

I need to make something custom but don't know what would be good to make if from.

I need someting this shape only deeper so I can push the head units back into it and avoid the curve.
