This may be a little long so pick and choose what you want to read. However, I graduated in December of 2013 so I am relatively "fresh out" of college and went through a lot of research and discussion trying to find what I wanted to study in college. This gives you a brief summary of my college decision and then where I have gone from there. Feel free to PM me for any more questions.
As far as choosing a college, I suggest going to a college with a reputable engineering program. Engineers are highly sought after regardless of the field. Which engineering field you choose with then reflect more so on the specific industry you can get into the "easiest"
I graduated from Clemson University with an Industrial Engineering degree. When I first started, I enrolled in the "general engineering" program that just gives you a taste of some of the "engineering" work you will be assigned to do. From there, I visited/researched/"interviewed" professors and students in electrical engineering and mechanical engineering. I was focused on the EE side of things because, like you, I wanted to get involved with something in the audio industry. During one of my visits with the EE department, the directed me towards the "audio engineering" field. I went to have a discussion with the head of that department and they had a LOT of really awesome equipment, but I came to find out that the requirement to get into that field was to have a focus or experience with recording/studio computer programs. Most of the people in audio engineering went on to work for Disney to mix different audio for movies, TV shows, commercials, etc. When I spoke with this guy about my interest in car/home audio, he reluctantly said that most people in Clemson's audio engineering program were knowledgeable of that stuff, but making a successful career out of strictly home/car audio installation is very difficult.
Overall:
EE = basically computer engineering. You could double major in EE and CE by adding 4 classes from CE. A lot of focus on computer coding.
ME = a lot of focus on statics and dynamics and fluid flow
IE = classes in statistics, electrical engineering courses, statics and dynamics courses, logistics courses, computer coding, visual basic in Excel, calculus...... To me, IE is kind of like getting a good understanding of most all engineering so your options for a career in ANY industry are wide open. I began to focus on human factors/ergonomics with the hopes of getting into the Auto Industry and then once in the auto industry moving towards the audio side within the company. I really wanted to work for BMW in Spartanburg, SC but getting into that company without a 3.7GPA is very difficult. I chose IE because of the vast possibilities once you graduate as well as its "focus" on management because I have always been a leader and enjoy working directly with people rather than sitting at a desk all day.
I wound up interviewing with 4 companies within SC: IV bag manufacturing, potato chip manufacturing, textile manufacturing, and a supplier for BMW, Mercedes, and Volkswagen that manufactured the base carpet, brackets, and heat shields. I then interviewed with a Georgia Pacific dimensioned lumber manufacturer in LA and Honda of AL.
I received offers from everywhere I interviewed and right when I was about to accept with Honda they retracted that position. I accepted and ELE (entry level engineer) position with GP in LA due to the atmosphere and starting salary. OTW to move to LA I received a call from Honda stating that they re-opened the human factors position at Honda and was bummed to have to turn it down. After spending 1.5 years here in LA I am going to transfer to Rome, GA as a technical director due to a dramatic pay increase, not having a someone to report to daily so I can create my own schedule, and to be closer to family. From there, I may look back into the auto industry but GP is a wonderful company.
ELE: with this position I have been able to work as a process engineer (quality control) in both the sawmill and planer mill, plant engineer (capital projects), production supervisor, and technical director.... so far. The plan is for me to continue working different positions from accounting to plant manager, however, due to the opening in Rome, GA I will be focusing on the technical director's roles, responsibilities, and expectations so that I transition to Rome with a vast understanding of what to do.
