Electricity is very important to car audo. Why is it not discussed more often?

[QUOTE="i2ain2thunder, post: 8413974, member: 631331"] Hi Chad. Thanks for the added information. While we're on the subject, it is my understanding this is how speakers operate for those of you who don't know. A speaker moves up and down depending on what direction the current flow is going. A speaker is basically just a big coil of wire inside a magnetic housing, whenever the electricity passes through the coil on your speaker, your speaker moves. Now lets add in how much the speaker moves and it's general movement path. Which you all have seen on a spectrum analyzer. The SA shows a graph of the signal the speakers are getting. The speakers will movements will be identical to this pattern. Now I believe there are 2 different concepts of clipping. But I think one of them, input clipping, happens when the tops of the waves get cut off. Now immagine the way the speaker has to move if you cut off the top halves of the waves, there will actually be millisecond pauses in the speaker's travel. This can be a huge problem for the speakers as they rely heavily on venting to stay cool, and once a speaker's coil has gotten too hot, you have a blown speaker and a nice hot glue smell. Many of the community I'm sure has experienced this. Please feel free to add/correct anything with regards to this thread, I claim no expertise myself, I just like to study. [/QUOTE]
