just spoke with my dad about this and with the way he explained it is that it is best to have a ground going from the amp to the extra battery(s) in the trunk and then a ground from the battery(s) to the frame while also having another ground going to the battery under the hood.

alaskanzx5 if i had the money i would do it but sadly 1/0 gauge is not cheap.

Gazookz Yeah but when having multiple runs of wire going to the trunk, you would have to have double the connections if running the ground to the frame in the front, and then from the ones in the rear too. It's just the way some do it and has shown to increase stability in the system if done correctly. It might be cool for someone on here to run the ground to the frame, and test it out. And then run from the front to rear and test it again.

alaskanzx5 i understand what your saying, i just dont think that running a wire front to back would make a difference in the ground. also you still put a terminal end of some kind at both sides of the wire even if its going from under hood to trunk. rather then a ground from front to back 2 grounds in back to me is more reasonable.

Gazookz The whole body of the car, even when grounding to the frame, acts like a long wire. The ground wire to your rear battery or amp still has to travel to the front. The one wire for the ground results in less resistance from terminals. Believe it or not, each ring terminal you use adds resistance no matter how you put it on (solder or crimp). That little bit adds up for the people in competitions and can gain on the meter.

But like I said the only people who really do that are the ones that have their vehicle dedicated to competitions or who are widely involved in it. And even then you will find people running to the frame. I'm not argueing that grounding to the frame is bad, I'm saying that is why people run a seperate ground sometimes.

alaskanzx5 and if you upgrade your grounds though out the car then to the frame and as short as possible it still the best.
