I've been into Car Audio since I was in high school, and got my first car (which I still have today).
Here is my 84 Camaro that I restored a few years back
Only drive it now on nice days in the Summer. The audio system is modest, added a 7 inch touch screen and using a raspberry pi to run OpenAutoPro. Turned out pretty good, would like to upgrade the PI at some point as it's only a 3b+.
