kinetik battery wireing?

[kevin25 10+ year member]

I have a 1400 kinetik up front and a 1400 kinetik in the back. It looks as it my local shop ran a power wire to both positives but I dont see a ground wire to ground wire on both batteries. It looks as if they grounded the back battery to the frame. Is this ok? ON the kinetik website they say to run two batteries parellel fun positive to positive and neg to neg..

As long as both batts are gronded to the frame its ok. They dont have to grounded to each other.

Ok I was worried there for a second. So as long as the front is grounded to the frame, which it is, and the back one is grounded to the frame this is ok? Is this still running them both parellel to each other this was also, and will they both get charged equal by the altenator? Why does there site say to run ground to ground and pos to pos to both batteries? I think there way you are getting a capacity of both batteries and my way I am only getting a capicity of one battery to the system, is this true?

Its good.

When you ground the car with the front battery, being the car is metal, it acts as a big wire, so when you connect another battery in the back, it acts like a wire completing the circuit.

Kinetik says to run (-) and (+) from the front to rear batteries because Kinetiks are for serious people and serious competitors know the difference it makes when you ground to the frame and running (-) to (-). There is far less resistance when you run 0 ga from your front battery to the rear battery. Grounding to the frame means using steel, which isn't very conductive compared to copper. And I'm assuming you've already done the big 3 upgrade along with a High output alt? Kinda pointless for two batts if you haven't.

Since when is steel not conductive?

If there is a battery in the back of his car well say 13 ft from the front battery. How is making a run 13ft away better off than to the frame which is probably 3ft away?

I'm lost, where did you see me say it isn't conductive? Of course steel is a conductor, but not even close to being as good as copper. The resistance in steel is far higher than copper, hence why companies use copper for wires instead of steel.

I believe going to the frame would be better eh? It's a much shorter distance. And seeing both batteries are connected to the same frame.... Just makes more since to me. Unless you know something I don't. I'm here to learn.

You can do either way, but electricity wants to follow the path of least resistance and 4000+ strands of copper wire have a lot less resistance than a steel frame.

But what I'm not getting here is the battery in the front is grounded to the frame also.

the electricity still has to flow all over the car. so if you give it a direct line to the battery the flow would be more efficient? its still a 13 foot run no matter what type of material used, so why wouldnt you use the least resistive.

am i on the right track?

Yeah, it is. But it's also grounded for the other stuff in the car, not just the stereo

Yeah, your on the right track. Copper is less resistive compared to the steel frame. A copper wire is a direct line to the battery, where the frame isn't. If you ground to the body the current still has to travel through all the spot welds and body mounts that hold the body panels together, compared to one direct line.

Manufactures recommend you ground to your chassis on as short of a wire as possible. The longer your ground wire the stronger the possibility of picking up noise, so they say.
