The math configuration is not there to support your claim. If you were a true electrical engineer you would know this.
But anyway, I am here trying to learn. Can you explain why using a ground wire bigger than a 8 gauge would be pointless? And also why are you running less than 12" of 4 gauge then run the other 15 or so feet using 8 gauge? Isnt that 4 gauge by the battery pretty pointless since right after the inline fuse it gets restricted again?
Thanks.

Yes I understand the faults in my system and they have been taken care. On the grounding issue, I said that its pointless because if your car is only grounding around 8 gauge then you would not need to ground more than that. In another case if you had a system that required a 0 gauge or so then yes you would have to change your ground wire out I agree with that. 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.

did this guy figure out his problem?
it DOES sound like an RCA issue possibly.
try unplugging your RCA's from the amp and then starting the car and then turning it off, simple process of elimination here. By the way, you dont ground a subwoofer, you ground an amp. You also said you have two amps, are they both grounded to the same spot? Maybe you mentioned it already but I got sick of wading thru the "im an electrical engineer" and "the math bla bla bla" crap...
