power acoustic amp issue

it's all just math and the number they put at a particular rated voltage. the higher the voltage the higher the number their going to put. example Crossfire and MMATS put there rated numbers at 13.8 volts b/c most vehicles can actually hold that voltage especially the newer ones. other amps that are CEA compliant are rated at 14.4 volts which most newer vehicles don't hold. take your Sundown amp that has a 150A fuse rating that you are saying puts out 2000, look at the electrical of those that have "clamped" those numbers. those guys are holding a higher voltage to be able to show those numbers. also just because you "clamped" 2000 watts does not mean it's unclipped or undistorted power. that same amp can yield slightly more power than another amp with the same fuse rating b/c it's going to be more efficient than those. if you can hold a higher voltage you can get more power out of your amp. back when I first got into car audio in the early 90s, all amps claimed power was at 12v. example Soundstream Class A 5.0 was rated at 12.5 watts x 2 @ 4Ω @ 12v with a 40A fuse, this same amp at 14v bridged would put out ~500 watts at 1/2Ω.

13.8volts * 60a fusing = 828 watts. But the MMATs puts out more than 1000w at that voltage. So either this amp is 130% efficient (impossible, it's actually around 86%) or your "fuses can't handle any more current than they're rated for" argument is flawed.

And don't take this as me trying to prove you wrong, I'm just trying to educate everyone on this subject. That's the point of the forums- to learn more about our hobby, correct?

Show me the actual out put of that amp and not what a company claims their amp's output is rated at. No amp is can endure a current draw higher than the fuses on them for longer than a couple seconds at most. You are still so wrong on the idea that a fuse can withstand higher than its rating. Fuses are designed to give when pushed at or to its rating. If fuses didn't do this than the ratings are worthless.

Are you trying to say MMATs amps, some of the highest end in the industry, don't put out rated power?

I'm telling you to show me an amp that defy the math of Ohm's Law and Physics Law of the Conservation of Energy. I don't trust any company's claim of power. I trust the math. Let's see this amp. I don't want to see a guy running an amp with a stout 16v electrical with a 1/4Ω load to the amp and you say it puts out more than 1.5x the rated power.

I'm not saying the amp defies ohms law. It's really receiving a current of about 90a through a 60a fuse for short bursts. (Ex: burps)

i'm calling you out saying BS b/c that is not what RMS means. maybe you should google what RMS means. you cannot pull more than what a fuse is rated at. you may get by with it once or even twice but the fuse filament will pop b/c they are made to pop when they reach there threshold. don't back out now, you talked all that game about knowing more than me now lets see it. what's a matter grasshopper?

When I was running in MECA I was burping 2500 trough a 30a fuse. Sometimes it would make it through a PnP run.

what voltage and what ohm load?

ohm load has nothing to do with amperage draw through the power wire other than higher impedances being slightly more efficient

Mid 13s dropping to 12.6.

2ohm. It was a ZX2500

I've practiced with my 5k wired at .7 15v. Got down to a 50a on burps and 75a for the 30 second run sometimes. It wouldn't always make it.
