Hello, I think I been using the wrong size fuse. I have been using 50 amp agu fuses on my Infinity 475a and 611a amps
From the manual: 475a amp's maximum current draw is 72A and the 611a amp's maximum is 69A. Does that mean I should use 60 amp or maybe even 70 amp fuses?

here are more info if that helps
611a amp:
657W RMS x 1 channel at 2 ohms, 14.4V
Fuse rating: 2 x 30A

475a amp:
90W RMS x 4 channels at 2 ohms,
Fuse rating: 2 x 35A

thanks
Chin

 

Honestly, stay where your at. If you go up more your just chancing the amp, in case it does fry. using a lower fuse it like a fail safe for it. IMO, leave it

 

thanks, i ran those two 50 amp fuses for over 5 years
