Audio system ground question

I am upgrading my system and scrapping the ****ty B&O. The Zen A-B device is touchy with the ground and recommends grounding amp to battery. I am using a bus bar on my amp rack behind the seat, 0 gauge run to the battery, 4 gauge on the rack to amps. My question is: Is it better to add another 0 gauge ground to the body from the bus bar?

You should change the thread title, maybe that will help get the attention of those who can help answer the question.

Is there a reason why nobody recommends going to the frame?

I would agree with going to the frame. On these truck to the body, no. If coming from the back seat area, G403 might be convenient.

I came through the floor right by g403, that would be a pretty easy point to get to with the bus bar. Again is there an advantage to adding this ground from the frame to the bus bar that is already grounded at the battery?

Anyone know if there is an advantage to adding a different ground point besides the battery to the buss bar?
TIA

Not sure why you think you need to ground the bus bar to the chassis if it is already good ground. But most of this is over my head anyway. I hope everything works out well for your project.

For my 2 amps (300w + 600w), I used the official ground points (G301 and G302) on the rear cab wall. I only needed 4awg gound wires, but these have worked fine for my install. Both runs were 3ft or less.

When I did my system, I ran both hot and ground from the battery all the way to behind the rear seat. If you're already running everything for the amp then what's one more wire?
