Graduation Project

Overwhelm, no...captivate them.  They're consumers, too, so they'll learn right along with the class.  Start making a list of the issues you have to overcome building a system, then arrange all the issues into an outline.  You might make a better and more interesting presentation by talking about the "big picture" instead of the very ordinary method of detailing a project from start to finish.

Begin with a visual picture, using both words and whatever actual visual presentation you are going to use.  This initial visual picture will be the overriding image among your audience for the duration of your presentation.  A recommendation would be the visual image of the school's orchestra on the stage.  This is a "big picture" image that would help a beginner understand why one would use the concept of a front soundstage when designing audio.  And the teachers will love it.

Another recommendation:  talk about the value of a custom-designed system compared to a premium OEM system (the teachers will relate to that).  This is where references to the individual instruments in the orchestra can come into play, and will more clearly demonstrate why the process of building a car audio system can make the appreciation of music more fulfilling.

You will soon have so much material for your 15-minute presentation that you will need to condense and rewrite many times.  But it will be worth it, because I see a good grade and some new respect coming your way after your talk.

BTW, you should keep all of your notes and staple them together roughly in the order that you worked this presentation out.  Hand this in for extra credit, because it demonstrates the work you put into it more than the formal presentation alone might prove.

That's another good idea.  Thanks.  If anyone else has any ideas, then feel free to express them.  I can always use another point of view.
