andreg3000 Posted October 1, 2009 Report Share Posted October 1, 2009 Probably a stupid question, but would it be better to do 1/0 gauge 2 runs pos vs 1 run of pos & neg? Currently have 200A mechman & D3400 up front, 3x D975's in the back. Just ordered some more 1/0 to do an additional run but don't know if voltage drop / charging would be better with a particular setup. I know ideally, you should have equal runs of both, but if I could only add one more run what would be the best setup? Thanks Quote Link to comment Share on other sites More sharing options...

Torres Posted October 1, 2009 Report Share Posted October 1, 2009 it wont hurt. but you're also only as strong as your weakest link, so it may not help either. Quote Link to comment Share on other sites More sharing options...
andreg3000 Posted October 1, 2009 Author Report Share Posted October 1, 2009 it wont hurt. but you're also only as strong as your weakest link, so it may not help either. Ture, very true. Now if I do add the 1/0 neg run, should it be from the alternator mounting bolt, or from the front battery neg terminal? BTW big three also done already Quote Link to comment Share on other sites More sharing options...
Saltine Posted October 1, 2009 Report Share Posted October 1, 2009 you dont need a full run of 0 guage ground to the back. your just wasting wire and money Quote Link to comment Share on other sites More sharing options...
andreg3000 Posted October 1, 2009 Author Report Share Posted October 1, 2009 you dont need a full run of 0 guage ground to the back. your just wasting wire and money This is what I initially thought and was therefore gonna do the extra run of positive and just beef up the rear grounds at several different points. But I have always heard its ideal to do equal runs of both. I don't want to waste $80-$100 on adding something that's not worth the improvement. Anyone else want to chime in??

I have always been told to keep the runs even, so 1 + 1- or 2+ 2-.

I have always been told to keep the runs even, so 1 + 1- or 2+ 2-. i really dont understand why people even run a neg run from the hood to the back. aren't grounds supose to be as short as possible? why not do 2 short grounds from rear batts to the frame, and 2 runs from the front battery??? seems like a waste in money to do neg. runs from the front.

Nightshade Posted October 1, 2009 Report Share Posted October 1, 2009 If your car is one continous chasis then you don't need to run a ground at all from the front to the back. The reason for competitors doing this is because their car's either are a split chasis or have a break in the body so they run a ground from the front to the back to keep the same ground for everything. If your car doesn't fall in this category then your okay to not use one of the runs for a negative and are better off to use it for a positive.
