Ground question

[Banginbass601 1]

Should I run my ground from the front batt. to the rear one or just ground it to the frame?

Just ground to the frame with both batterys and you will be good.

That's your choice. I usually ground to the front battery and do the BIG3 in all my installs.

As Ryan said it is preference. If your on a budget then you can get away with grounding to the frame. Definetly do the Big-3.

Which will give me better voltage becuse I'm gonna have 3000 rms with only two batts and a h.o. Alt

Depends on your vehicle and the wire you are using.

Generally if you are using a single run of 1/0ga wire and your vehicle has a good conductivity, grounding to the frame is the best option.

If you are using multiple runs of large gauge wire and/or have a vehicle with poor conductivity, going directly to the battery is the best option
