Big 3 question

[4Fifteens]

So I have 2 optima yellow tops, 1 in the front and 1 in the back. I wanna do the big 3 but I have an old car with a 105amp alternator. Well I was wondering if I should use 0 gauge or 4 gauge wire. Some say I should use 4 gauge because I have kind of a low output alternator. Any help would be great

0ga so you don't have to get bigger wire if/when you get a bigger alt

if your not planning to get a ho alt just do 4awg and dont replace the wires just add to existing and run a 0 ga from front to back

Always go bigger on the wire. The 4 gauge usually isn't much bigger if at all than the stock wires

Well I'm not getting a h/o alt. but I heard 0 gauge with little alt is a bad idea and 4 gauge would be better

0 gauge for sure mate, it's a bit harder to run, but it's worth it in the long run.

you heard wrong... the larger the wire the better regardless of alternator size

The bigger the wires the better.
