Dual AGM Battery & Big 3 or 4 Questions.

[RVATahoe]

Good afternoon family!!!

I recently added some bang in my truck. I have two amps. Pioneer 700+ watts 4way for the highs & Taramp Smart 3k for the subs. Looking for some write ups or some guidance to adding another battery under the hood and doing the big 3 or 4 or whatever. Currently have a yellow top optima on the driver side. Looking to add another yellow top on the passenger side. Do I need a isolator? I will upgrade the alt soon as well.
2006 z71 factory alt currently.

What hooks up to what? which wires go where?

Thanks fam.

All I did when I ran two batteries is had 1/0 audio or 2/0 weld cable either works. Running positive-positive fused between the batteries. Same with grounds. Use the same wire for big 3. Wire from alt + to battery + and ground the alt bracket to the frame along with the battery to frame. That’s your big 3

isolater is not required, you can run them in parallel or use a isolator your choice, I ran mine in parallel both are connected to the starter, both are connected to the alternator and both are grounded, nothing else required.

Make sure both batteries are the same make and model. They also should be approximately the same age.
