This is a monoblock Autotek SX1200X. The birth certificate says 1184 watts @ 1 ohm, but if that were true my poor 12" Orion would have been blown by day 2. Something is fubar.

60 amps x 14.4V = 864 watts at the absolute maximum. But it'll be even less than that.

Jonathan do you think it will hit 600W?

Maybe. Don't know, honestly, fuse size isn't a good indicator of true RMS power output, especially with a company like Autotek. Usually it'll be something like 115% of full load draw, which would

Sorry, didn't finish the post. Meant to say fuse size is often around 115% of full load draw, which would put you in the 700s if that were the case.

Fuse Opening Time:
A fuse does not blow when the current reaches its rated current. It is designed to pass its rated current without opening. A fuse will take varying times to blow under different conditions. A fuse will pass significantly more than its rated current for a very short time. It may take 10 minutes or more to blow a fuse at 25% over its rated current. The table below is an example of the specifications for a slow blow fuse. You can see that a 20 amp fuse may pass 40 amps of current for as long as 5 minutes before blowing although it probably wouldn't take a full 5 minutes to blow. The times for other fuses will be slightly different.

%of amp rating Opening time
110% 4 hours minimum
135% 1 hour maximum
200% 5 minutes maximum
