[QUOTE="dezahp, post: 8553160, member: 672194"] So, I was also wondering. It's probably a stupid question but how do I determine how much amps I need when I get fuse holders/blocks? If I run one 4 gauge power wire to d block from the battery, then is one 120 fuse holder enough at the terminal? But how do I determine what rated fuse I need for the 2x power wires after the d-block to the amps? Like, I got 2x 120 fuse holders from the 2x amp kits I ordered. I think same or basically like these.
