I've always been a huge SPL fan and the motto usually is "the uglier it is, the louder it is." I primarily went to II to get more hands on training on alarm installation and welding but I also learned first hand how to design and construct a classy install. Learning from professional instructors who have been in the industry for decades is a real asset for anyone who wants to further their knowledge in the industry or anything audio related. I took home skills and techniques that I wouldn't have received anywhere else. Going to II not only increased my abilities as an installer but I had a blast doing it. I didn't even want to go home. It's like a vacation for car audio enthusiasts.
