Can someone explain this to me?

So, we all know that people generally use wire in the range of 12-8ga from their amp(s) to woofer(s). My question is, if we're using that thickness wire to transfer anywhere from 1000-10000+ watts to a woofer, how in god's name does that tiny, almost hair-thin piece of copper running between the tinsel leads and coil come close to handling all that?? I've always wondered that when seeing pics of woofer guts, and don't understand it. I'm embarrassed that I'm halfway through EE undergrad and can't solve this. Is it just because it's totally uninsulated and is a short run?

Very simple. Higher voltage= less amperage as per Ohm's law( in comparison to the power input of the amp). Then as mentioned the fact it's so short comes into play. Just think of how thin (the inside of)a fuse can be relative to the current it can handle.

agreed. i was just thinking that the other day. i got this big ass 0 gauge wire and then this fuse that just has a tiny piece of metal in the middle.
