no but they are all above 80% and there are plenty of amps thst are not 100% efficient and still do rated....
So why does everybody say apsm's don't do rated due to fuse reconnemdations?

Mmats dont have fuses
Amp draw is much greater than fuse rating. A 120 amp fuse can have 240 amps of electricity flow through it without blowing. I had an old autotek that had 160 amps of fuses but max amp draw of 269 iirc

so why would they recommend an 80 amp fuse on something that draws much more?
yep. my autoteks fuse recommendation is 60 amps, lol. this is because music is dynamic, and fuses will not blow if your surpassing the fuse rating for short time periods. The purpose of a amps fuse is to protect the amp. you aren't protecting a 2k amp with a 200 amp fuse that will take 500 amps for long enough to fry the dang thing.
Because that's how all Amps work. Not just mmats. Sundown etc draw more than the amp rating. It's just that they are less effecient so they have to allow for a higher fuse rating. To prove this I know everyone had known people who have shorted there amps out and not a fuse on board popped but amp was fried. This is because it was such a short surge.

yea i know but that just seems like a pretty drastic margin. 1400w amp and 80a fuse.
there prob one of the best amps you can buy, thats why they are a pretty penny vs other amps. It has always been there knock.

You don't need two amps. The speakers come with crossovers to help protect the tweeters.

Perhaps you changed something without mentioning it here? Maybe a loose turn on line? I dunno man...but we'll take it. Hopefully it keeps working. 👍
