Which Battery Post for Amp if NOT using Fusable Links

Ok,
So I don't want to use the fusable links. Which battery post is best to Tap into -> Option A or Option B - > See Link

I am seeing conflicting advice from around the web. Couldn't find a single picture of amp install with a close up connected directly to a terminal as you do with all other cars. I had Monster battery cables on my old TL.

Can anyone recommend a battery ring or connector they know would fit to support a 0 gauge? Could I squeeze a 0 gauge batt ring onto the bolt?

Appreciate any suggestions!

Option B is the best place as it utilizes a 5/16 post. If you pop the cover and trim the side of the bottom cover the 0ga wire will fit. U will need a 0ga terminal lug with a 5/16 hole.

Option B is also the safer one.

Option A is BEFORE the BST. So in the event of an accident and the BST triggering, you're accessory will still be live until it's own fuse blows.
