[QUOTE="Gawdzila, post: 8068200, member: 653459"] Hey [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Having a physics degree, I feel qualified to say that periodic motion is one of the most important subjects in all of physics. Indeed, periodic motion has a lot more to do with car audio than you think. Both electrical signals and sound waves behave very similarly, and they are both modeled almost completely with periodic motion -- which is why the electromagnets in speakers can so directly translate an electrical signal into music, or why you can hear a "60Hz hum" sometimes if you have a speaker next to a wire carrying wall current. That oscilloscope you'll be using measures electrical signals for things like frequency and amplitude. As you know, sound signals [I]also[/I] have a frequency and amplitude. The only differences are that with sound you can hear the frequency as the pitch, and the amplitude represents voltage in an electrical signal, but volume in a sound signal. There is a very tight relationship between what you will see on that scope and what you hear coming out of your speakers. Unfortunately I'm just a very beginner in the ways of car audio, so I can't give you a good procedure myself. With just a little digging, however, I did come across a couple of good instructions: [URL="http://www.bcae1.com/settinggainswithscope.htm"]This article[/URL] has a write-up with some explanation about the underlying principles. [MEDIA=youtube]VrOoOxO6A1s[/MEDIA] should also give you some pointers about how to actually, physically go about using the equipment. Study hard, and dig beneath the surface -- this fun and useful little car audio project has the potential to teach you some very deep things about how the universe works. Good luck! [/QUOTE]
