When I was young, wiring a (tape deck) in the glovebox meant wiring it in and having it loosely laying in there sliding around with cassettes jammed all around it as well as insurance papers (& rolling papers), burrito wrappers. Too many parties to go to to waste time doing a good job
That's a great job and a super clean dash.
I always remember my brother used to steal my car when I was at work (69 Nova) and drive it around all day. When I'd get home, the gas tank was always empty. So one morning, I put in a Judas priest (heavy metal) tape in the tapedeck, cranked the volume and locked the glovebox. I had no idea that he was going to drive my 85 year old grandmother home that day (50 mile trip). As soon as he started the car, it started playing. He said he played with the radio buttons to try to shut it off but nothing happened (didn't know the deck was in the glovebox). About 20 minutes down the road, the last song played and they breathed a sigh of relief. Just when they thought the nightmare was over, they heard a click as the auto reverse kicked in and side 2 started playing
Needless to say, my grandma had words for me when she saw me again but I cured my brother from stealing my car!!
