Been out of the game awhile, need major help please fellas

[d luv]

I have a 1999 Buick Park Avenue and am getting ready to purchase the things that I am still missing in my setup. My main concern is my Audiobahn 2300hct powering my 2 12" JL W7's at 1ohm. I have a yellow top for the trunk and a capacitor as well, here is where I'm lost as I've never used an extra battery or a cap before. The AB has 4x40 fuses, and I also plan to buy a 4 channel amp that does 75x4 rms {not sure on model yet}. My first question is how many fuses should I run throughout setup? Currently I have a 200amp ANL fuse, should I run this 18" from the battery {front duralast, or trunk yellow top}, or should I run a 200amp ANL at each battery?

I Also plan on purchasing a distribution block, should this be fused? If so how big of a fuse for the AB output, how big for the 4 channel output? Should the capacitor be fused also? Should I upgrade the big 3 to 1/0 gauged as well? The wire I am looking to buy is http://www.wireandsupply.com/product_p/sgx-1-fslash-0-fslash-01.htm , will this do or should I step up to http://www.wireandsupply.com/product_p/sgx-2-fslash-0-fslash-01.htm ? I am sorry for the lengthy post but I am really confused, even more confused than you after reading this frantic post. Thanks again for the help everyone.

IMO you should fuse from alternators to batteries. Batteries to batteries. battery to distribution block. the wires off the block i don;t think need to be fused and LOSE the cap and add another battery.
