[QUOTE="keep_hope_alive, post: 7524180, member: 576029"] most distribution blocks reduce the output wire sizes. but you can get distro blocks that have rings for smaller wires - so you'd want a 1/0 in and 4 awg out. if you are running wire that is smaller than the fusing at teh battery, and if the amp doesn't have built-in fuses - then you need to get a fused distro block. if the amps have fuses and the wire is sized for the amp fuses, then you technically don't need a fuse distro block even if the wire is smaller than the battery fuse. the reason for this is as follows: battery fuse: provides short circuit protection for the wire. amp fuse: provides over-current protection for the amplifier and wire. in some cases the battery fuse is also used for over-current protection for the wire. it is typically safer to just use fused distro blocks, and it's nice being able to pull a fuse to kill an amp in case of setting adjustments or the general desire to turn off an amp while adjusting levels.
