Question about installing a second battery

[Crich03 2]

I installed a Optima yellow top battery as my second battery. I previously had a 4 farad Cap in the trunk and the power wire was ran from the main battery to a 0 gauge splitter and 4 gauge was ran from the splitter to the Cap and the Sundown SAX1200d. I removed the Cap and added the battery in the same spot(I added a 150A fuse to the 4 gauge run from the splitter to the secondary battery). Should I run the 0 gauge wire coming from the main battery directly the second battery or is it fine the way it is? Again I have the batteries fused with 400A total between the 2.
