[QUOTE="The_Quiet_One, post: 8486351, member: 614562"] Quoting your wikipedia article "The movement of electric charge is known as an electric current." so I'm confused here. What particles are you talking about? There are no charged particles that flow along electrons...the electrons carry the charge themselves. Look man. There are two main charged particles. Protons and electrons. Protons are bound in the nucleus with neutrons and the number of protons dictate the element of an atom, so that leaves electrons. The whole concept behind how a traditional loudspeaker works is the flow of electrons are moving with some velocity along the wire which is exposed to the magnetic field of the motor. The Lorentz Force law then describes some of the fundamental physical behavior which can then be used to derive Amperes law and the resulting magnetic field in a coil. (I would list equations, but without advanced text editing they would look garbled; you can look them up if you wish) Now one catch is the convention of saying electrons have a negative charge is you have to be careful maintaining the sign convention.... Unless you specifically need to know the underlying theory behind electricity many profession certification programs can get by with providing basic formulas and guidelines, so many people have a YUUUGGEEE (feelthebern16) misconception about several EM topics. It's not like plumbers need to know the anomalous properties of water or someone who builds computer for a living needs to know the underlying concepts behind things like volatile memory, caching, semiconductors, etc...? NEC is a best practices guidelines OP can safely use 12 or 14 gauge wire in this scenario at the expense of bit more voltage drop of which he won't hear the effects and a slight amount of additional heat along the wire from the additional power dissipation. Now saying that, the weak points/points of failure will be his connections between amp and subs which you can likely offer good, practical advice about that with your electrician experience.
