[QUOTE="n2audio, post: 8372518, member: 540940"] Actually, that's not true. A fuse is meant to pass its rated current indefinitely. 110% for 4 hrs min. 135% for up to an hr. Even at 200% it won't blow instantly. In your example (1200w/80A), if you played full volume music pre-clipping it would run forever. Full volume sine waves would probably blow it in a few hrs. Clipped music would probably blow eventually...depends on the degree of clipping. Doesn't really matter though b/c in nearly every case, if an amp is truly capable of that kind of power it will have more fuse protection. Fuse/power appx is certainly valuable with the cheap brands, but just leave it at 8-10x. There's no point in trying to get any more precise than that. It's WAAAAAY more accurate than a lot of cheap brands specs. With good or even decent amps it's pointless. [/QUOTE]
