[QUOTE="Savant, post: 170971, member: 546108"] At 2 ohm, you are drawing more current (or, more to the point, the higher output causes a higher input to be needed).. This means you are driving the amp harder and it needs more juice (well, only if you are trying to get loud.. at low volumes non of this should matter).. Now, you say 'instantly'.. what does that mean? You turn on the amp and the fuse blows? or you are listening to music and once you get to a certian 'loudness' the fuse goes? Is it going about the same place regardless of the fuse (when you put in the bigger fuse, could you turn up the volume more than with the smaller fuse?)? If you are popping fuses as soon as the amp goes on, you have a short somewhere.. If it's directly releated to volume, then you are running fuses that are too small (which means either too small of a power wire, or fuses too small for you amp).. I'm presuming it's a Class D amp? so, I'd guess around 125 amp max draw? Your power wire should be big enough for that (and the manual should actually have that in it someplace, I'd think) and the fuse should be the right size for the wire... Hope that helps.. [/QUOTE]
