I've wanted to apply to various car audio shops around my area of Daytona Beach, FL, and apparently I need some sort of certificate to install car audio. I googled the topic and found various trade schools that I must go to, but nothing directly relating to the certification. I know that most of the installers are college students who wouldn't have the time to attend a trade school, so can anyone tell me where I can get such a certification? Is it a course I attend for a couple weeks? Any feedback is appreciated.
