I want to go to college and study how to install lighting and sound systems/ speakers. Anything from aoutomobiles to theatres, concerts, etc?
That is not a college degree. That is a trade.
Installing, that would be a trade. Not a four year Bachelor degree. Try looking at your local community colleges.
Try to learn it without going to college.
An electrical installation course would seem to fit the bill. Many colleges will run these courses. Auto electrical is of course a separate subject.
