I've always had an interest in car audio install and of course, now that I have a boat, Marine audio installation, but haven't ever learned even the basics. I wouldn't even know where to begin. If I was younger and didn't have a steady career, I'd go apply at Best Buy and learn through them, but since I'm a busy guy with my career and everything, does anyone have any resources where one can learn the basics and become an expert? I'm talking BASICS..... I don't know the slightest thing about soldering, electronics, grounding, etc.
I'm thinking maybe a community college course on electrician type stuff would be a good start... Any recommendations?
