if you wired your amp mono and was putting out 1200 watts and if your other amp wasds making 80 watts by 4 then total amp draw would be around 125 amps so you would use 150 amp breaker.

you can also add all the fuse values of the amp and use the total at the battery fuse.

You will be drawing a max of approximately 118 amps, I would suggest you get a 120 amp breaker. You always want the fuse to be as close to the max draw as possible.
