We use our trucks as off grid 4x4 campers. The high output alternator and wire kit made a huge difference in charging my batteries. Usually my batteries would go dead in the middle of the night from charging devices and heater pads. But with high output and this cable I can make it through the night before the alternator fast charges everything in the morning. I wanted to say thank you and leave this review.

I recently installed the BIG ZERO kit, and I’m genuinely impressed with the difference it’s made. The pre-assembled cables made installation much easier than I expected, and everything fit perfectly with my new HO alternator. The quality of the wiring is the best, and I’ve noticed more stable power delivery to my stereo and SPAL fans, especially when pushing things. This kit is a solid upgrade for anyone looking to get the most out of their alternator.

This wire kit made a BIG difference on my mazda. I purchased this kit after installing my new alternator and the difference was OUTSTANDING. I guess it depends on your car wiring but mine in the rx-8 was tiny compared to this huge cable!

I was glad to find a much easier solution than the 'big 3' wire upgrade. Most cars only need to have the main battery cable upgraded which is exactly what this power bastards kit provides. This is very easy to install. I like the fuse and the wire is extra flexible so I installed it for an almost factory look, haahaha. Thanks power bastards! Noice name BTW!

I picked up this wiring kit with a my new alternator on tuesday based on the techs recommendation and sorry i can't remember his name. This wire kit made a huge differnece in my system performance. Thank you!!! Powerbastards!!!
