Default what makes a Brazilian amp give up the magic smoke?

I've been running my dual 1ohm taramps dsp3k with my dual 1.4 ohm sub for 5 months now at .7 ohms and it's never heated up or caused problems.
I soft clip according to the clip light every now and then.
Why do these amps fail when wired below rated?
Is it just too much current flowing through the board when wired lower and pushed harder? I've read TaylorFades threads but im still curious. I've read several threads on these amps when I bought my amp but I'm just curious on what people think. No bashing please

i've never ran brazilian so shot in the dark answer based on readings.

You could have a lot of box rise? ** reason its not blowing, not a reason it will blow **

Felt like i needed to edit that in.

Mounting them poorly. This causes failure with any amplifier. Just so happens, the failure potential is higher with brazilian amplifiers because they weigh less.

Having too high sustained charge voltage.

Brazilian amplifiers never stop making output power so if you keep driving them in voltage, which is equal, to an infinite volume control or setting gain stupid high.. it will eventually pop the FETs or the microcontroller (usually from excessive rail output)

There is a general guideline of DC voltage to stay within so that doesnt happen.
It works fine too.

That's basically it.

Everyone should know not to wire below their stable load.

Taramp's has recently released a couple new amplifiers with 5way system protection like korean amplifiers and more focus on vibration control to help aid in the "abuse" some users put amplifiers through.

Between now and the next couple years, Taramp's is going to look different.. Much revisions coming.

I get the fact of its trying to make more power then the components can actually handle. I charge at 14.8 steady. What kind of ac voltage should I set my gains to on an hd8000?

Hopefully someone like Taylor gets his hands on a new one to prove that protection system works. There's always going to be those few who will say they suck no matter what Taramps does to them. Hopefully this will alleviate some of those naysayers.

I've never seen one of my Toyota cars/trucks go above 14 volts so I'm good on that.

Should I increase the output on my audio control lc8 converter to keep the gain on my amp lower?

So, is it the amount of current that blows these amps when you try take the maximum rated RMS when you wire too low that blows these amps? Or does something just get damaged no matter how hard you push the amp when you wire below rated and eventually failure?

I've been really happy with taramps so far. I'd like to upgrade to a bigger model but I I'll have to sell this one and I really like the 2.5yrs of warranty I have left

"Any amplifier outside it's operating limitations will cause it to fail"

Pretty much a blanket statement that's true. Brazilian operating limitations are just different

I know what you mean. I was just curious if anyone knew the specific cause for failure.

Amp vibrations
Wiring under ohm load
Over 15volts.

Only things I can think of.
