Would it be better to run 0 gauge from the ground of the amp straight to the negative terminal of the battery instead of hooking it to a bolt under a seat?

Guessing you have a second battery in the back? You can do it either way but if you do have another battery you will have to ground that as well

Best solution is to connect the negative of the front and rear batteries directly and then ground amps to the rear battery.
