oh, one thing i did notice neon, no one has used any equations to try to explain anything......
i though about a few, but figured i be better off sticking with the water.... The water model does make things relatively easy to understand. The one thing that it doesn't answer for me is, take my QS8's.... If placed within 10 feet or so they only require 16 guage wire, (or a very narrow pipe). But in my situation they are about 40 feet from the power source, so I was advised to go with either 14 or 12 guage wire (a thicker pipe). Is this because the voltage supplied isn't sufficient to "push" that current that far? Or is there another property of electricity that the water model doesn't account for?

It is the resistance to flow of the smaller gauge wire, over long distances, the smaller wire builds up to much resistance within itself over that length, while a larger wire has less resistance over a longer length. We are now getting into new terminology here as well, inductance, impedance etc. the finer qualities of electrical theory.

I know there is some loss with longer runs of wire, which is probably where those equations Dakkon eluded to come in to play.

That's pretty much it. Lower gauge wire has less voltage resistance per foot. When you have more feet of wire, you need lower resistance to keep it below 5% of the impedance of the speaker.

Electricity has always been a mystery to me, having never studied it. These explanations are very enlightening indeed, and in fact even fun to discuss. It makes me want to study it further just for the sheer joy of it.... Uh oh, was that a nerdy thing to say?

Mm. I think with a sportbike, you're halfway there anyway.
