In my final high school years, my parents gifted me a 1980 Corolla, and it became my experimental electronics lab for a while. I installed a pull-out stereo, a separate amplifier, various permanent and movable speakers, etc. I mostly had the pros installed them, but I was always tweaking things at the wire-harness level. I enjoyed my music EXTRA LOUD, with minimal distortion. And I had one of those basic aftermarket alarm systems. And there I was, constantly tripping the alarm for various reasons, and we lived in a safe neighborhood, so it was mostly an additional annoyance when I set it off, or armed it, or disarmed it: I was being super ostentatious. So my proudest DIY mod was to install a shiny toggle switch in the dashboard. The toggle switch had the sole function of disabling the alarm by cutting its power. So I basically handed it to the crooks who came along in a few weeks to steal all my cassettes. But honestly, I doubt that anyone on that block was sorry to see me separated from my music at that point.
