As stated by Dave they don't go crazy indepth into teh acctual accustical theory of sound. If you wanna go to a school you can Pay me about a 1/4 of the cost i will teach you everything i know(MECP First class installer/Custom Installer certified) and give ya the MECP basic book go over test's with you and you can watch me do what i do best. Then Ill set you up with the Acctual MECP test and you can Take it and be a MECP certified installer for alot less. The thing is anyone can learn anything if they want do. Doesn't mean there gonna be good at it. But with a MECP cert you can go to 90% of the worlds car audio shops and atleast be considered for the job. Without that cert the place of business is taking your word unless they have seen your work.. So if your ever intrested weekend whenever I would be glad to help.
