Use a star ground for amps, 2nd batt and caps?

[ghart999 10+ year member]

I run all my amps (3) to a dedicated ground point via distro block. I am soon adding a Battcap 800 and two 1 Farad Monster Cap Stiffening Capacitors. Don't comment on the worth of them. I just want to see if they make a difference or not. Have done big 3, Red top, 200A alt, etc.

Mainly I want to know if I should ground the caps and batcap to the same distro block or give them their own separate grounds? I have no noise now, so the star ground is working so far.

Not sure if in theory an extra batt and or caps should not share the same ground as amps or not. Thanks all.

Single grounding point is better
