Ok well I took a few photo's of my head unit install on my L wags. My bro is a glazier so the obvious choice of material was Aluminium because there is so much lying around the garage.
Anyway, first up... Stereo choice! I only realised until afterwards how this can help (a little) I accidentally bought one with the wiring harness plug recessed into the head unit, this gave me a little more clearance which is ALWAYS helpful here.
Next was to kind of measure up how much space we actually had to play with in there so after some precise measuring with my trusty eyeometer we decided to make some mounts that would screw into the factory mounting brackets and the security bracket thing that the head unit slips into. Also we decided to use the original cover plate with a little extra widening:
Just screwed it in with some self tappers:
With a few adjustments here and there the cover plate can slip on and off easily enough but it does stick out a bit and that bright metal is quite annoying:
So bending up some ally and spraying black to use it as a sleeve was a brilliantly simple idea.... (not mine haha)
so it looks neater now but i'm going to take that security bracket out and paint that black too
Oh and another thing... things can be messy back there and if you're a cheapskate like me and want to use some of the factory wiring for the front speakers, I found that both left and right wires were the EXACT same colour! There is nothing telling you which wire goes where so to figure out which is which I wired up the speakers in the doors and got a 9v battery. If touching the positive and negative with the stereo speaker wire makes it crackle you got it!
So that's it so far.... oh and btw I bought a 2nd hand head unit and it didn't come with that finishing sleeve that goes around the face of the head unit. that would have been handy. Anyway that was a lot easier than I expected.
