[QUOTE="HardofWhoring, post: 8864718, member: 674149"] As for the wire and fuse sizes: Figure out how many watts you want to run from the amp, (min), or what you think the amp is capable of (max). Best to go max, and if you're going minimum, then go at least 20% over that. Take your wattage, divided by voltage, (Used to be standard), 14.4 running volts. Let's say 5,000w / 14.4 = 347 amps. Your amp should have it's own on board fuses. The fuses you are adding to the wire, are FOR the wire. The purpose of the fuse is to intentionally create a weak point in the wiring, so that if something happens to the wire, that hopefully the fuse will blow, where it is protected, and easy to fix. Your fuses at/right off the battery, and at/right off the distribution block, need to be equal to or greater than the fuses for the load at the end. The wiring needs to be capable of handling more than the fuses. 350 amps is more than 1/0 can handle. You're close to 2/0, and that would depend on the length. If you wanted to use multiple 1/0 you could put 300 amp fuses, or even drop it down and put 250 amp fuses, and even that depends on length, but you're probably good. Not sure how many alts I've seen over 400. If this is your plan you might have better luck finding a dual alt bracket. [/QUOTE]
