Anyhow, with pushing close to 100A in audio alone, would upgrading the vehicle's power cables be something I should do, or only if I notice some dimming issues.
As for that analogy, yes......But the pipe you already have is bigger than required for that flow....There is no restriction currently.
Don't let the 100amps distract you, you probably will never pull that...EVER.
Mine is rated 150 main, 60 and 80 on fuse distro.....I am running 3 amps that arent as efficient as your HD's. You are fine...
