I'm not familiar with the fuse ratings on the Brutus... But the (Maxsonics) Hifonics amps don't do what they claim. Realistically, you'd be getting closer to 900, if you are lucky at 1 ohm.... But you're not getting 1200 watts out of that amp at 14 volts. It's not that hifonics/ maxsonics products aren't good, they are just over rated 20-30% A bunch of people run Hifonics amps and love them.
Granted this isn't your amp, but it's just for an example.

You could put 500-600 Unclipped RMS per CVR in a sealed box and they will take it. Wouldn't recommend sending them that much in a ported box, at least for the average person.
