[QUOTE="dipitydoo, post: 7477737, member: 567383"] not sure what amps you are using, but if both of them have fuses in their chassis, you do not need a fused distribution block. you can save yourself some money and get a simple non-fused distribution block, unless you really want that voltage display. a common misconception is that fuses protect the amp. that is not the case - they are there in case of a short in the amp, it stops massive current draw from heating up and causing a fire in the power wires. as far as the fusing itself, at the battery, make sure to fuse for the wire capacity. a good rule of thumb - choose a value somewhere between the total value of all amp fuses and the wire capacity itself. i don't recall off hand how many amps a 2awg cable can safely handle at lengths of 15 - 20 feet, but lets say if its 200amps, make sure its 200 or less. if your total amps fuse values are lets say 150 amps, then the value of the fuse at the battery should be between 150 - 200 amps.
