With a ~270amp alternator, you will absolutely need to upgrade the Big3 Wire to at least 0g.
I think this is your problem.
*Be sure the positive Big3 wire is fused (at the battery) with a fuse rated no higher than the maximum current rating of whatever wire you are using.
Guys, he is HERE for proper education. Let's help him out instead of pointing him elsewhere.
What gave you the impression we were trying to send him elsewhere and not help him? We already told him he needs to do the big 3 in 1/0, he doesn't really need to spend more money on another battery, and he needs to set his gain properly. He stated he was going to have a shop do it and I suggested he get a dmm and follow the tutorial on here. How is that pointing him elsewhere?

No, a cap will not be helpful. There are a few threads on here that will explain why a regular capacitor will not benefit your electrical.
