[QUOTE="Deiimos, post: 8830126, member: 682903"] Are you using 4 gauge for everything? If so, you technically only need to fuse it at the battery up front. You can fuse each amp if you want to or if they do not have built in fuses, but if they have built in fuses I wouldn't bother. Just run the 4 gauge from the battery to distro block, then 4 gauge from the distro block to each amp, done. Fuse the 4 gauge at the battery with a 120A fuse of course. Now, if you are using smaller power wire for the lower power amps, you need to fuse each "smaller wire" at the distro block. Example, if you were to using 4 gauge from the battery to the distro block, you would fuse the 4 gauge near the battery with a 120A fuse as you normally would, then at the distro block you connect an 8 gauge wire, you fuse the 8 gauge wire as close to the distro block as you can (within 12-18") with a 50A fuse, then run it to the amp. That said, you'll probably be okay running 4 gauge for that setup. Listening to music you are not going to max it out, maybe if you sit there with sine waves playing full tilt you'd stress it, but that is unlikely how you will be using it. [/QUOTE]
