You can gather some time between making all those products and start your answers right now telling the Audio forum WHY you say that this amplifier can make 11500W in 2 ohms if the maximum voltage is 119.57V?
Because with that voltage the max is 7150W.
We are saying in our website :
a) WRMS Power (1 ohm) to 13.8 V: 16.500 Watts b) WRMS Power (2 ohms) to 13.8 V: 11.100 Watts c) WRMS power (4 ohms) to 13.8 V: 6.200 Watts d) WRMS Power (1 ohm) to 12.6 V: 14.200 Watts e) WRMS Power (2 ohms) to 12.6 V: 9.500 Watts f) WRMS power (4 ohms) to 12.6 V: 5.200 Watts
Remember that 119,57Vrms is only for condition d) . This is the RMS voltage over the load. Frequently SOUNDIGITAL says that their amplifiers have regulated power supplier and STETSOM doesn't have . The advantage of non regulated power supplier is that you can increase the voltage to 13,8V and get 16.600 Watts in 1 Ohm because the internal voltage is not more 190V . If the SOUNDIGITAL has one regulated power supplier , the internal voltage is the same in both situation ( 12,6V and 13,8V). So, how the power suppliers of STETSOM amplifiers are not regulated , then in 12,6V at 2 ohms , the internal voltage will increase from 190 V to 209 V and the internal current get down also and it decreases the losses from 11% to about 7% . So , 209V - 7% => 194,3V/1,41 => 137,8 Vrms . So, 137,8*137,8/2 => 9.494 Watts . It is exactly the item e) [/QB]
Working at 12,6V in 209 volts whith 200V max mosfets ? And whith 13.8V, 14.4V, 16V or 18V input voltage ? If your power suply is not regulated is impossible work. This is a good way for blow the amplifier.

Exactly, I already showed the Safe Oferational Area for the FET used on this amplifier.
If the power supply reach 200V it will make the outputs FETs explode. 200V is the minimum breakdown voltage, is the voltage where the insulation material on the component breaks.
It clearly seems that some numbers on Kidao posting are wrong, because this is still simple electronics.
He stated that the amp at 2 ohms is at 209V, so at higher impedances the amplifier will de at iddle at more than that.
He also said that the power supply is not regulated, that indeed will result in a substantially increase on the voltage if the battery voltage is at 14.4V.
Those are FACTS, not bashing, and if they want to have a voice here on foruns they can use them to reply technical arguments.

come on tj this is just a healthy debate to answer questions and explain answers, personal attacks arent necessary bro......and are counter productive to this topic. Thanks to Stetsom for answering these questions for us.

And by the way, we just discovered that the amp is fine, and the problem wasn't related to the amp. I would apreciate if you don't say stuff like that on a forum without being 100% sure.

All bests. [/QB]
Yes, it was my initial idea , but I had difficulties . I will thrash by this way in the next posts. Excuse guys !

Excuse me for the other members , but I need to answer this point . STETSOM makes search over the components . We dont use only what is in the Data Sheets. Transistors like Capacitors , they have tolerances also. The IRFP 4668 in the 14K2 has about 20% of tolerance . It means 240V . Ufa!!!!

Hey guys , i have long time not posting in the forum, the reson is because some people use the forum to make problemas. I think SD is doing a great job ,but the way Murilo do ,is not good for the company. If you Murilo have eny problemas with Stetsom why you no just beat or records? I don't have eny thin against SD. The only thin is that stetsom amps are louder,and don't burn soul easy. I just like to know how you do 5 years warranty in USA, when you guys only do 1 year in brazil?????
Do you have stock in the USA? SD have amp repair center in the USA? What you do if your amp burn in a customer car?
Look Murilo you have try go to all stetsom dealers and competitors , and give free amps , we have sold . we don't need to giveway amps to make people try or amps, they know that stetsom did the first 180db in the db drag lanes, stetsom did way more for the USA clients than SD dose. Sorry guys but this guys is not all you all think.... sorry noting against SD or USA clients is only personal thin with this individual.
thanks

and Steve this post was not intended towards stetsom and im sorry if i afended ya but this type of fude should be taken up in pm. i just love the way murilo stated at one point that sd will not bash another product well i think this is bashing who cares what stetsom dose maybe he needs to worry about his own product first.

Please, don't you dare comparing our service with yours.
We give 5 year warranty because that is related to the product quality. I invite you to do the same.
We give in North-America LIFE TIME warranty to our competitors... Why don't you do the same?

I remember Stetsom giving free amps Alan. Murilo, what happens if a SD amp needs to be repaired? That is a major concern of mine.

not to get in a pissing match but i have talked to many people that have had stetsom amps go bad and some of them take for ever toget repaired there is a post some where on this site about it and stetsom just got a repair center in the USA which is DB-r and alan i remeber u coming on here last year or so and being the same way as he is if not worse so now u talk down to him about the way he is u should look how u where and still are to this day on here i say let the product and the customer sat show who the best is if the amps are good the customers will say

First of all, the only one individual in North America who got a free amp to compete was TJ, a SD8000, but borrowed, of course.
Our spread mechanism is not giving free amps, but making very good ones, once a customer buy one, his friends can see the amp, other competitors can check what the amp can do, and the chain goes on.
Bernie, we, SounDigital, repair them, in NY or in Canada.

Murilo, I was refering to Stetsom giving amps to competitors not SD, but you just put me at ease with SD being repaired in NY since I am close to that location.

One thing to remember when the dust settles, Stetsom is being sold in america by americans and repaired by americans, SD is being sold by Murilo and repaired by murilo. What happens when murilo deciedes he has made enough money in the uS and is ready to go home??????Dont be decieved by things that are to good to be true because usually they are.

I hope this pissin match ends soon! nuff said You guys SO FAR.. make the strongest amps on the market as far as I know. Why the hell are you both b**ching at each other. People are running your products and doing good scores...ain't that enough? I'm sure you already know that this type of heated conversation is slowing killing your level of respect in many peoples eyes. Is it really worth it?
Build your amps and let the lanes and builds decide which amp is best. nuff said.
