SAE-600d - Is it a 4 or 8 gauge power input?

 

I am reducing the system in my daily driver now that I have a project vehicle. So I don't need all of that heavy 1/0 gauge in my little jetta. I will keep the big 3, but want to reduce the main line running to the back of the car. Going to use a 600d to power a single SD2-12D2 in a birch box to save a bit of weight, and lift the ass of my car a hair. 

 

The SA-10s will move to a Blazer, until I can get 4 SA-12s or 15s.

Those are 4 gauge connections because the amp can do 740 @ 1 ohm. 8 gauge wouldn't handle the power. But that's just my opinion.
