The fuse rating is when the fuse will blow and prevent current flow. Take my Xtant 403 for example. It can draw a maximum of 60 amperes of current during normal/peak operation. Therefore, my fuses are 60 amp fuses, this way, if my amp shorts, or the wire shorts, the fuse will blow rather than allowing 500 amps to flow through my amp to ground and nuke it. Amplifier efficiency really doesn't matter as a guage for current draw because it fluctuates so much. Loud bass hits cause spikes in current draw, this is why capacitors work, to prevent headlights from dimming with bass hits.</p></blockquote><p></p>
