Where to ground amp?

[Mosin]

Do I place ground from amp to 2nd batt then to ground or straight to ground?

Run it all to the 2nd batt, just make sure both batts are connected. There was someone a while back trying to run his system off just the 2nd batt without having it connected so it could get a charge..

I am doing a new install using two batterys (Kinetik); one cranking and one deticated for the audio system. I am running 0 Gauge cables from cranking battery (+) to the audio battery (+). So if I read correctly I should conect both (+) and (-) terminations between both batterys so that they both will charge? Should I still terminate a ground local to my audio battery that will be located in the rear of my Yukon?
