As the cage with the alpine was quite deep i mounted it about halfway out and twisted the 'lug bits' so it was secure at either side of the dash.And once the stereo was pushed into the cage i put the standard alpine trim surround bit over the face and onto the cage as normal and then trimmed a bit of black accoustic felt about 2" by about 12" and then folded the short 2" bit over so it chunky and then squeezed it along the top gap of the stereo and down the sides and then trimmed and excess hanging down the sides.It finished it off a treat and the flip out bit folded out and around at a good angle.
