But grounding your head unit with a bigger gauge than the battery, yeah you bet your azz its pointless, the math does not allow this to be true in any case.
I dont think anyone was takling about changing an 16-18 gauge wire into a 8 gauge one. That would be pretty pointless.
You pointed out that if your car needed a 0 gauge wire, then your battery => chassis should be the same. Wouldnt that go the same for if your car needed 4 gauge wiring? A lot of time the car would come with 8 gauge from the factory. But once you start adding amps, there is a bigger strain on the alternator and battery. And it would be smart if you upgraded the grounding on both.
