if your talkin about the fuse holder at the battery then yes. but i'd make sure it's a good breaker, something using the "hall effect" and not a magnetic kind. Monster makes a good breaker. but if your talkin about running all the amps off the one breaker w/o a d block i'd be abit worried about how ur installing the ampss

Fuse/CB ratings should be compared to the wire size/capacity you are using to feed those amplifiers. The 125 amp number should be used to size the wire. You are skipping a step.

your wire fuse or for the wire not for the amps, you must fuse according to the wires ability or you will have some problems

fuse each amp separate. If one was to fry and pulled lots of current while the others turned off it may not trip the breaker and start a fire. Fuses and breakers are for safety don't skimp. I would fuse to the wire size up front first then if you have an extra batt one more fuse there. then a fuse to each amp at the fuse rating said by the manufacturer of the amp.
