Opinions on welding lead for power and ground wires?

[Skoty422 10+ year member]

I noticed some people saying that welding lead was better than car audio wire and being a welder I looked to see if I have any. And sure enough I do. I have 2/0 and 2 gauge. The 2 gauge looks just a little bigger than the 4 gauge car audio I have. I was wondering if this was ok to use.

I will be running a RF power bd1500.1 (150 amp fuse) and a ppi pc275 (35 amp fuse). The RF will only be pushing 750 watts.

I will also use the 2/0 to do the big 3 upgrade if it is ok.

Now the question I have if it is good to use is: Should I use the 2 gauge for main power to amps or the big 2/0? And what would y'all reccomend using for the amp power from block? 2,4,8 gauge? I don't have the fuses or blocks yet so I need a little direction as to what I should purchase. Thank you all!
