Well, I have not done the big three, just the big one LOL, Ran a 4 gauge wire from behind the Alt to the top of the positive mount, made a huge change throughout the car.
The 4 gauge wire was a 4ft or 5ft piece from the parts store for $5. You can run whatever gauge bigger, but 4 gauge worked for me.
Here is were I ran it.
Can kinda see it here, I have loom over it. The drawing above is for reference.
