Double run opinions (neg/positive from front to back)

[Nates_Veloster]

I put this in my alternator thread but think that it requires it's own thread. I done a search and didn't find anything that will hit peoples opinions straight on this subject.

After doing some research there seems to be both sides of the argument about doing a run of both positive and negative from front to back battery. I am trying to figure out how much welding lead to go with and trying not to throw away money that isn't needed.

So what are your thoughts about running positive and negative from front to back?

Is it worth it or just run positive from battery and hit negative on a strut or ground to metal?

How much power are you going to run?

Thanks young. It didn't show that on my search. I must have done something wrong. I am running 2500 watts total on a fi bl 12 and mids/highs.

Depends on how big your alt is and what kind of car

No problem bro.

My head is spinning so I am glad they simplified it. Under 4k, just chassis ground it instead of full runs. I have a 90 alt right now (factory) but trying to upgrade but no one makes them. I have a hyundai veloster - 2012. From what I am gathering its better to ground chassis it than full run both.
