Amp Fusing To Max output Formula

[treesive 10+ year member]

A few weeks ago I came across a post that had the conversion to see about how much output an amp could give based on its fusing. Could someone post the link to this or give the formula?

Thanks

Roughly 10w per amp.

IE, my 9.1 is 120a, so we guess it does 1200w, which it actually does.

Also, amperage x voltage= watts

100a x 12v = 1200w, but that's at 100% efficiency.

100a x 12v x 80% = 960w at 80% efficiency.

Maybe not dead on, but food for thought.

THX. All I needed to know.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I really disagree with using these formulas for basically anything. Manufacturers rate their amplifiers' power output for a reason. Just because the fusing may be a bit larger doesn't mean the amplifier is going to produce more than rated power. I don't know what you want these formulas for but they're worthless IMO.

Well I bought one of the Autotek M4000.1D's as a cheap backup to my 9.1 and noticed it only had 140A in it so wanted a quick formula to get about what it actually would do.
