age 15, some friends went out stealing HU's from BMW's, I never wanted any part of that - too scared I'd get caught. But I figured out how to install them, so everyone came to my door for ghetto install work with needle-nose pliers as wire strippers.
Never was too proud of that but at 15 I can't say I had the best judgement. And it got me involved it car audio for the last 21 years.
First system was a Linear Power amp driving 2 pr of Jensen 6x9's wedged between the rear deck & rear window (no enclusure!), all running off a Pyramid deck & Pyramid EQ with spectrum analyzer.
That hurts my ears just thinking about it.
