[QUOTE="bikejunkie223, post: 1197545, member: 563147"] I don't think fusing for the wire is smart at all, you only need to fuse for the maximum amount of current that will be drawn through it, so if you want to be able to unhook your amps power supply line and weld with it, you will need a bigger fuse. Those amps probably wont draw more than 100amperes. Heck, you could try the 80, and if it pops, you need a bigger fuse. The idea of a fuse in a circuit is to protect the car from abnormal operation, the fuse should be just above the current draw for your amps and doesn't need to be any higher. Most amps give you a spec for max current draw, add this amount together and you know your fuse rating, or, add the values of all the fuses stuck in your amps (if they have fuses, not all amps have fuses built in) and this is the size of fuse you will need. With those amps, it's unlikely you even need 1/0 wire unless you are running a hugely long distance or like the engine bling look of uber-wire. [/QUOTE]
