Need help with grounds


Recommended Posts

Posted

I have a 05 tahoe and I have added separate alternators just for the audio system so I can run it at a higher voltage. My question is , when i run my power wires back i was going to run grounds back too but i'm unsure where to ground them under the hood. Should I hook them to the engine block or the frame in front ? Or my 12 volt battery? I appreciate any help/ideas you can give me. I have 4 xs power batteries in the back of the cargo area.

I hook them to my battery up front, build a nice buss bar that you can bolt all the wires to the battery with. Tons of pics in build logs with multiple batts and alts.
