Like my poll asks: "How do YOU do it"?

I ran two cables, and then added a secondary ground to the rear. I used 0 gauge cable... if I were to do it again though, using 0 gauge I would have just run the power wire. and grounded at the rear.

The chassis is a much better ground than any cable. Provided you properly ground it under the hood and in the hatch.

I don't question my grounding techniques. In my Saturn I ran one of each, I was told by an Orion Tech to do it. His take was that newer cars' metal not the same grade / quality as older cars.

In my Stealth, I will run two 0 gauge but they will be both for power. This way if I need to jump into a H/O alternator for my sound system, the two runs can support the 220Amps without a voltage drop due to the resistance of the wire.

I already have Big Tyla's ground kit in 0 gauge, just need to get it installed....feel like coaching me at your place Matt?

What would be the point of a ground back to the bay? Just for the alternator and ECU/sensors? Everything else is grounded around the chassis isnt it? I wouldnt think it would make much, if any of a difference for stock electronics, if it was grounded in a different spot...also wouldnt it cause a bigger voltage drop if you had the long negative cable?

sublime - i had to re-read your post.First time i read it i was thinking you were saying ground a negative cable you ran. :) But now i get it. heh

As long as the proper gauge was used you would not drop voltage.

any issues with having battery in the back and race track rules and regulations?

You really need to check with your track. But normally as long as you have it properly mounted most tracks are fine. It also needs to be a sealed battery. Now, it's when you start getting into different leagues of racing. They will require you have an easily accessible, externally mounted kill switch as well.

I don't track my car well except NG but my planned kill switch

I ran two 0 gauge cables back from the engine to a Flaming River cut off switch and then to the Optima Red Top battery. One 0 gauge wire connects directly to the Mechman 250A alternator, and the other goes into a distribution block for the fusible link and any other powered items in the bay. I also grounded the battery with 0 gauge wires to the bolt where the spare tire hold down goes into. My alternator then has a direct ground to the chassis. I constantly see 14 volts at idle (probably due to the alternator as well) and I have a shit ton of electronics. I also have a couple of grounds from the engine to the chassis as well to might/might not help. So far, I have had no issues with this setup. :)

saw pics of your car on knukoncepts, what wire of theirs are you using?
