So today I got around to doing my Big 3. I did it all my 1/0 AWG Kicker Hyperflex. Let me know what you think:
This reading is with the car off (no alt)
I left some of the stock wires on but I figured it doesnt matter because the electricity will take the path of least resistance. The only thing I was wondering about was if it mattered if the new wires were above the old wires on the battery terminals, should I have the 0 AWG as the first ring terminals sitting on the battery terminals or does it not matter?
Also how could I test that my big 3 is working? I tested the resistance of my ground spots to my battery negative and it gives the same reading as when I touch the two ends of the DMM together (0.05 Ohms) So I know they are good, any other tests I could do to?
What do you guys think?
