Upgrading your power wire and grounds from your battery with a thicker gauge wire. I choose to use 0 gauge wire. So you do positive terminal on the battery to the alternator with a fuse inline close to the battery. Then you need to do ground terminal on the battery to chassis then to engine. Which would give you the big 3 but I did the grounds the same way that it came from the factory. It's negative terminal to body to frame then to engine. Doing this helps to provide the battery and charging system with optimum power when you have extra drawls on the system such as compressors and a amplifier. I'll post some pictures later.
