first thing u do is cut the terminal from the positive cable and remove the negative completely
run the zero and the 2 gauge wire from your trunk all the way to the engine bay using a connector connect the zero gauge to the old positive then do the same with the 2 gauge just connect to the engine bay the just connect the 2 wires to your battery and your set but remember to strap it down somehow

That is NOT the way to do it. For starters you don't use different gauges of wire for positive and negative leads, they should be the same. Consider the voltage like a water hose, the in and out need to be the same size.
Secondly, the ground should be bolted to the chassis by the battery. Running it back to the engine bay creates a shit load of extra resistance that's not required. The engine will be grounded to the chassis already and you're not going to see a ground loop as long as both grounds are good and clean.
