Ground Wire

I think your boss was looking at the $$$ amount rather than the fact that you installed a better ground. I always say, better safe than sorry.Jeff

Using a thicker wire than needed doesn't hurt, he probably was just being cheap. There's no reason that they need to be the same gauge as long as both are thick enough for the current.2009 Pontiac G8 in planning stage

You could/should have just stuck with an 8awg ground. He was probably mad because you wasted good wire. But, in my opinion, use the same size ground as the power wire unless you have to extend your ground pretty far.

Well, I did it for 2 reasons. 1) It was about a 3-4 foot run.... which is not a big deal, but also 2) the install just looked nicer with the 4 gauge. I had to run two ground wires (we were fresh out of d-blocks, bossman forgot to order more) for the amps. Even after explaining that to my boss (who by the way isn't even certified, and I am), he still said you have to use the same size ground wire.Sean Cawby
