Great vendor. You cant please everyone thats for sure, but went out of his/their way to get me what i wanted. Which meant changing my order at LEAST 3 times. And a paypal mishap.

I want to order the 0awg kit that is on sale but I have a question about the positive battery terminal that comes with it. It only has one input for 0awg wire so how do you guys do the big3 upgrade and run power to the distribution block?

If you have a dual post battery use the side posts

Actually I just bought the 0ga kit today, and installed iwth the help of D3R3K tonight, I also have the big 3 done, It has 1 4ga slot(big 3 alt wire trimmed down) 1 0ga slot(amp wire) and 2 8ga slots (misc computer junk in car), it worked out for me FOR NOW , lol However 4ga big3 wire will work, but I hated trimming down my 2ga wire :( lol

So for the big 3 would it be okay to use a fused 4awg from the alternator to the battery and 0awg for the other 2 grounds?

Will be OK, but wont get the most out of the big 3.
