Will someone please explain something to me?

I see people using runs of 0 gauge wire and then using tiny *** pieces to connect them to their battery/alty/ground etc. Wouldn't that be a huge bottle neck?

Depends on how small the peice is diam and length. short runs of smaller wire can carry equal current but they have to be short runs.

i figured that, but it seems counter productive.

I dont get what u mean by tiny *** pieces, I use ring 0AWG ring terminals for my connections for big3/grouding/battery/etc

Length vs. cross sectional surface area.

Look at the filament of a fuse -- even a big *** 250A fuse is a very small piece of metal that can pass massive current with minimal resistance - the cross sec. area is small, but it's so short it presents minimal resistance.

A 1/0 terminal is what, 5, maybe 10 times the size?

It's really short, it can carry the current that whole inch.

probably has something to do with how dense it is too. If u think about wire it's a buncha tiny pieces of copper/metal wound up together, it conducts fairly good. But if u just have a huge soild piece of metal it would conduct even better. But it would be kinda hard for people to run copper pipes thro their car and into the amps. Could be done, but be way too much trouble.

well there we go.

You'd be surprised on how little a piece of solid stock has to be to successfully carry the current of a large wire. As stated above, look how small of a piece of metal is required to carry 250 amp load (Fuse)
