Did this one a few years ago but the guy was getting ready to sell it so I snapped some pics.
Here is an older install I did it was about 2 years ago. The car was a 96 Vw Jetta it was my 3rd time doing head rest tvs it was very tricky and still is to me lol. But here are some picks.
Front Doors
Head units "didn't do the fiberglass but and getting ready to learn it"
Rear tv's
Rear Deck infinitys don't ask me why he wanted them in the back and the polks in the front.
Cd changer
It also had 2 hifoinic amps mounted to the rear seats and the wires tucked threw the seat itself. There was also a box with 2 kikcer l5's. It was nice to bad I did not get picks of them.
