The ground wire has to be at least the gauge of the power wire.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Also you want to make sure to make your chassis ground to bare metal, to prevent having any resistance, which also helps prevent the annoying engine whine.

Thanks. That is the answer I was looking for. I didn't know if it could be smaller then the power or not that is why I didn't fill in all the info about the amp.

No, it has to be the same, no more or less, You'll have your amp choking.

But..... there are some cases that are exceptional.

94legend, we are going to have to hire someone to follow you around and correct the misinformation you're spreading around! "You'll have your amp choking"? You can have a ground wire as big as you want, as long as it is at least as large as the power wire. Now do I have to keep repeating that?

the ground can be as big as you want, truthfully...electron theory is that electrons flow from negative to positive

but like a pipe full of water...if you want what goes in, to come out at the same rate... its gotta be open the same amount on both ends

That's what I already agreed to. My ground wire is the exact size as the power wire. In fact, I grabbed some industrial electrical wire from work last year and the ground and power are the same wire. I was only having a prob with it when putting in my cap because it does not bend very well from of its size. I did get everything working properly today.

Thanks for all the replies.
