I was just looking at some old pictures of the engine I took out of my parts car and couldn't help but notice how small the wires for the alternator are!.

The + looks like 8-6ga, and the - looks like 12-10ga. Seems to be overly small, especially considering its low strand count crappy wire. Considering that at any time up to 90+ amps are trying to flow through that wire..... bigger could make a noticable difference.
Has anyone ever replaced it with like a 4ga + and 8ga - (car stereo wiring) leads before?
I'm pretty sure the + lead just runs through the main engine harness, and terminates at the junction block above the battery tray, but I'm not sure where the - lead terminates. Anyone know?
