A yes I have one run of knu klmx 1/0 to the back battery, now I had it just grounded in the back but im going to run a ground from the front battery ground cause i heard its better, well im thinking of going ahead and adding 2 more runs, 1 power and 1 ground, would this help charge faster buy doing this? also what if I ran one of the power wire straight to the alternator would this be better

It really depends on the resistance of your car and the quality of the grounding location.

I would take a meter and wire and test the resistance of you car's ground path (rear grounding area and negative battery terminal) before you pull the trigger on buying more wire.
