[QUOTE="HardofWhoring, post: 8842100, member: 674149"] From the under hood battery - you fuse that wire as close to the terminal as possible, and on it if you can. That fuse needs to be more than the total at the end, but less than what the wire is capable of handling. -- (You are creating a weak point so that if something happens, it happens where it is protected, and can be easily fixed. Any wire from the battery to the fuse is unprotected. As long as your fuse is the weak point in that part of the circuit then that will be first to go). From the second battery, you either run dual dedicated wires to their own amps, with fuses as close to the terminal as possible, or you run a larger wire that can handle more then what the fuse is. That fuse would most likely be the same as the first one, needing to be more than the amps, and less than what the wire is capable of. That would go to a distribution block. That distribution block would need fuses at or more than the amps, and the wiring from the distro block to the amps would need to be capable of handling more than the fuses at the distro block. Ground ends at chassis. Both batteries and amps grounds are ending at chassis, find your best way there. Not sure what your amps are, but if you have two amps, and both are good with 4awg, then you don't need two batteries. Not sure what your setup is, but if you don't know what a battery isolator is, you might want to see if that is something you want to add to your setup. (Not needed, just if you want to use your batteries one at a time). [/QUOTE]
