I did my first full radio install on my friends 96 civic the other day. It was pretty interesting having to remove the stock radio then install his sony. I had to wire splice and put electrical tape for the harnesses (civic to sony) and the radio wouldn't turn on at first which I wasn't surprised since I did the wiring myself with not much experience. tried again, still nothing.
I figured I had a bad connection with the wire or the radio didn't work. I tell the guy, he goes and turns on his car, radio comes right on, problem solved. Either way, I think I might wanna get a career change to mobile audio installer. too bad the economy sucks right now and nobody is hiring for anything.
