thats 4 awg in the middle, for crimp ons i used 3/4" copper couplings.

i flattened them over the ins. and wire, i used a punch on them to hold better, then drilled thru works great, and saved a few pennies:)

 
4/0 is half the resistance of 1/0, which means half the voltage loss, and while pulling 300+ amps that can mean .1+ volts
First, the Big-3 wires are not long enough to have voltage drops. Second, the only way you will see a difference is if you're running a 350+ amp alternator.

He's also only running an Orion 2500D. Max draw of 277A at 100% load, 75% efficiency, and 12v.

i have to agree. for the the big 3 thats just a waste of time/money. for power wire it may be needed when you upgrade to two 2500d's.

 
for now, u ever heard of adding on?? so when i add another 2500d i dont have to run multiple runs, easier to just do 1 wire.
You're still not going to be drawing that current through your engine or from the alternator...

If you're running 5kw you definitely shouldn't be using chassis grounds. You'd then need multiple batteries in the back, which is going to supply most of the current.

 
not a waste of money when its free, y should i buy smaller wire when i have all this already? as for time doin it anyways. so your sayin the big 3 is a waste of time?

 
batts and 2nd 2500d are in the future i dont see y its that big of a deal, if you dont like it dont post, obviously im using it regardless of your opinion but thank you for your .02

no if you would have took the time to read you would have realized i was saying that big of wire for the big 3 was a waste, not the big 3 but you seem to have plenty of time/free wire so w/e.
