Pimped my grandma's ride
It allows electricity to flow easier, it's part of the Big 3 upgrade.I figured 4 gauge is fine for now, if I wanted more than 500 or so I think I might need to upgrade my battery, alternator first!
ALSO someone mentioned to me to run a second ground wire off the battery to the body of the car? Why is this?
