2/0 gauge and lug opinions needed please

[d luv]

Hi fellas I have a question that will I'm sure be easy for you to answer. I have never ran bigger than 4 gauge wire, never upgraded the big 3, and never dealt with any of these following products. First the wire I will be ordering is http://www.wireandsupply.com/product_p/sgx-2-fslash-0-fslash-01.htm . The lugs I will be using are http://shop.genuinedealz.com/Marine%20Electrical%20Supply/Tinned%20Copper%20Cable%20Lugs/00%20AWG%20Tinned%20Lug/?sck=12205831 . My question is what size ends should I get, they offer from 1/4 - 5/16 for the 2/0 gauge wire. I plan to use them on the 2/0 gauge upgrading the big 3, I plan to use them on my battery terminals, and I plan to use them on any grounds throughout my setup.

Final question should I ground the 2/0 gauge to the chassis, then run that to a T-block with 4 gauge to the amp as that is the biggest wire the amp will accept? Thank you all for your help. I'm sorry for all the similar posts the last week or two, but I am new to a lot of this stuff and want to make sure I have everything covered before I order from the web. Thanks again

First of all, you sure that wire's legit? Seems pretty cheap to me. And that's not the size of the "ends," I'm pretty sure it's the diameter of the hole for the bolt. If you want to be safe, you can just go with the smallest, and drill it out if you need to go bigger. Otherwise, I usually just go with 3/8".

I'm not sure what a T-block is, but you can just ground your amp straight to the chassis with the 4 gauge.
