Amp Gauge "Sorta" Bypass Question

I’m no electrical guru by any means so I’ll state that right from the gitgo. So I reasoned if the factory used a single 12 gauge wire from the alternator, then 2 paired together should take the place of a larger gauge wire which I don’t have. Instead of running it as stock, i am running it through a maxifuse through to the battery positive as per wiring information I found through slantsixdanNo, I am not running an ammeter but a voltmeter in my Dakota Digital cluster. So your thoughts of running it to the stud on the starter relay I think it’s basically the same as what I’m doing except you’re not running through a fuse before connecting it to the stud.. waiting to hear what others think
