Wire size Q

Okay I've been wondering this for awhile. When I get my system hooked up, I will be going with 2g power wire to a distro, then 4g to my 1500dr, and 8 to my 400.4 I was wondering if what Size ground wire should I use. Is using 8 for the 400, and 4 for the 1500 okay? Or do I have to use 2g since thats my main power wire size

It really just depends on the distance and the current flow. As long as it is the same gauge as the positive, then you are set. It's usually most beneficial to have a ground that is as large or larger than the positive.

I'm personally getting ready to install my sub amp (er, that is when I have time to build the box to go with it) and have run 4 GA to the back, to a distro and just running 8 from the distro to the amps. It's a very short distance so I'm not worried. However I think I'm going to have 4 GA grounds on each amp.

K just making sure, I knew it was supposed to be the same as the power, but didn't know if it had to be the same as the main one, or the size from the distro.
