In my brothers car, he had the older model 5 channel alpine amp, and we were running an 80 amp fuse, if we ran a 60 the amp would cut out all the time because it wasnt getting enough power.
i prefer to keep it safe and put the exact sum of all the onboard fuses. lets say a short got pass the big 100 amp fuse and reaches the amp....thats not good.
