Jeff Stetsom

Hello there people, We Stetsom has been in the market for more than 20 years, about 10 years in the USA working with competitors We are located in Brazil in the city of Presidente Prudente, São Paulo state. We are one of the biggest card audio in South America, an Industrial facility with 3000m2 of built area in a 6000m2 terrain. Automated production capability. Worldwide Exportation. All this makes STETSOM the biggest company in its segment. This is a partial view of one of the assembling lines, STETSOM as assembling lines with modern pneumatic machines that facilitate the high productivity and quality. and before we sell them to our customers STETSOM executes the final test one by one of its amplifiers with modern measuring instruments where all the electronic parameters are analyzed and checked. We have about 8 lines of amplifiers, but we only have available for export in the USA only the Vulcan Digital Line Dub ST Line Thunder Line Vemon Line (new line i will talk more about it and they get here in the USA ) The Vulcan Digital Line are most famous line, the line that Alan Dante use to break the World Record of 181.7db The vulcan Line are Class D amplifiers with a pretty small size compare to some in the market How we can make high and quality power with a such a small amp ?? Because we use less of higher rated components. They are actually quite impressive(and expensive) parts. Much better than super buildhouse parts. Not only that, but the SMPS carrier frequency is considerably higher than other amps, which means they do not need to have as much transformer core area or input/ouput filter capacitance. That means smaller cores and a directly smaller footprint due to not having the need for so many capacitors. Stetsom dont need to use much transformer core area because our amps SMPS (switch mode power supply) is HIGHER than other amps then This means that the transformer that it feeds can be much smaller than one connected directly to the line/mains. you know not having need for many capacitors. it has a P.I.C that controls the power supply and protection circuitry (microprocessor operates on a 20MHz osc crystal ) The P.I.C is our protection mode for the amplifier is a microprocessor that takes care of the amp Which it helps, on the performance which we dont have to use fuse in the amplifier The vulcan line is a full range amplifier that they response from 20hz to 15khz (so models goes only to 8hz) They all have one full range channel output, with a low pass crossover and subsonic filter Vulcan digital line Full Range(20Hz a 8KHz) Amplifier with Low Pass Crossover(50Hz a 8KHz) 14k2e 11k2d 7k2e 5k2e Vulcan Digital Line Full Range(20Hz a 15KHz) Amplifier with Low Pass Crossover(50Hz a 15KHz) 4k2d 2k5e 1k5h pictures of 14k2e The Vulcan line has a amazing efficiency performance of 80 to 95% so you can have a idea @ 4ohms 93 to 98% @ 2ohms 89 to 92% @ 1ohm 83 to 88% (this is not a test results this is a sample) that's why are so strong in brazil for daily use, because we have a high efficiency The Vulcan line is a daily use amplifier, not only for burp like a lot of people think about it 5% of the whole production in the factory for the vulcan line comes to the USA, 90 % of them are use for daily system with music in brazil thats where we are pretty big, as the Vulcan line has a big frenquecy response, a lot of people use them with loudspeakers and woofers like this The Dub ST Line is a Class D full range 4 and 2 channels amplifier from stetsom This line is perfect for a installation with one subs and a pair of speakers you can use the 2 channels in bridged going to mono block channels and use for the subs and giving a nice amount of power to them and use the other 2 channels for your speakers The Thunder Line is a Class AB full range amplifiers 4 and 2 channels amplifiers they can be use and just like the Dub St like i said on the top , just use for you normal setup for your speakers both of this Line has a High pass and low pass crossover in the amplifier to help tunning Any Questions ??

Hi there, Please let me know if anyone needs shirts !!! http://www.facebook.com/#!/photo.php?fbid=398785396806021&set=a.102618086422755.5393.100000236916317&type=1&theater

Hey there people, Alan is finally back and ready to compete again September 29th in Brazil, PR He did 181.2db with his new car setup !! Now with 5 subs check it out Im pretty sure we are going to see a 182db score soon just more info, i still cant get a hold of him to ask more questions but this is what he posted on dbdrag.com http://audioforum.termpro.com/topic/36/826.html thanks Hall and every one here in the forum... nice show... its my first burp in brazil than we just did smal score for now.i use 56hz doing 181db at low frequence... the real 180db i have 4 amps(Stetsom 14k2e)Linked and 6 subwoofers(2 18s and 4 12s] uuuuu... about the car be legal or not we are talking about extreme cars, they allways going to be crazy ... the name is extreme class , than lets go extreme...

Well thats not true, If you do the testing for yourself, you will see that one cable is enough We recommended a 72mm cable which is around 3/0 to 2/0 cable for the big amps and for the 7k2e only one 1/0 is fine and long you dont have the cable bigger than 4 feet long

Depends of your electrical system, No !!! You need a 7k2e because of the impedance rise and many other factors with the 7k2e you will have enough power even to burn them !!! lol but sure the 5k2e can push them but it all depends what box you have and whats your goal with it !!

You should have no problem doing that, If you wired down to 0.7 nominal impedance the impedance rise will go around 2 to 2.8 ohms on the reactive load thats should be as long you have enough power to give to the amplifier Depends of your electrical system you should be able to get 10000 to 7500 outta the amplifier Please let me know if you have any more questions and im sorry for the delay, I was in a long vacation =) but now im back

Hi There, Well im pretty sure you never seem a Stetsom amplifier, Stetsom wont put the name on the Line, just to make more sales on big amplifiers If we say they give the power they do give the power on the rated voltage power Stetsom tested all amplifiers before they go on the market, they are tested inside the factory with competitors and daily We are pretty well known though the world because our amplifier are high efficiency on power to tell you the truth, Stetsom amps make more power than they are rated follow me on facebook and you will see many builds and more info - http://www.facebook.com/profile.php?id=100000236916317 Hey there, Whats the old model that you are talking about ?? They are attached just like the way they were before, but we just add more supports And about your question about rated power can you please rephrase it For instance the older vulcan 7kd that says SPL competition on it, are the newer amps attached too the heat sink the same why that amp is? On a setup that has the electrical to keep the voltage the amp is seeing from dropping below 12 volts does your 4k do 4000 watts? Does the 7k really do 7000 watts? Does the 14k really do 14000 watts? Does the 19k really do 19000 watts?

This is the new Vulcan 25k2e Here is is all the specs on it any questions ??

No there is no way and why would you wanna do that ????? you only will damage your batteries and also you wont get more power outta the amplifier 14 volts is the best voltage for the amplifier our amplifier they make power in low voltage you dont need do that here is a article about batteries, that goes to almost every brand Proper Way to charger your battery

Well The 24volts amplifier is the future of car audio There are many good things about a 24volts system Like you said if you have a 12volts system for you to make 20000 rms you will need 20 batteries but on the 24volts you only will 10 batteries to make the same amount of power half of the money on batteries and you still can charger the batteries will your 12volts alternator Now we have two model in 24volts - the 19k2e and the 8k2e Because the amplifier works with more volts and less amperage which is the best for the amplifier - our 24volts amplifier are 90 to 100% efficient because there is less amperage going though the amp and producing less heat

Im talking about the Input power on the 45k !!! it is 240 DC volts You can used the standard 3/0 gauge but for this amp we recommended you to use welding cable 3/0

Hi there, I am sorry but i dont know where you heard this from, we dont do that We only ask some basics questions about you and if you know what you dealing with because there is a lot of high school students on this the forums and they think they know how to build a big system For the 45k2d of course we going to ask you some questions, THE QUESTIONS IS TO HELP YOU SO YOU DONT HAVE ANY PROBLEMS If you have the money and wanna buy the equipment we will sell to you, we try to help before selling the equipment so we dont get a bad reputation from bad installations Did you know the 45k2d is a 240volts amplifier ?? no a lot of people know who to install a 240volts amplifier and not even know how to use the power Im not pointing anything, i dont know you maybe you are a guru on car audio but im just want to be clear about us picking who uses our equipment There is no such thing

Well, Lets do the math I dont know how many subs you will have and what kind power you will need for them You should go first with the power that your system will need Lets say since you want two 14k2e You want to put on the subs 10.000rms to have 10.000 rms at 12 volts (without dropping to 11volts like you dont want to happen ) If you are making around 10000 to 8000 for 30 secs you will need to supply around 1000ah With 90% of efficiency on the amplifiers If yo have your car off, it wont be enough because only have a battery bank of 720ah ( and its depends of your wiring because you can lose so power there too ) But its hard to know what power you will need without knowing this How many subs ?? Load impedance on the amp ?? impedance rise ?? Car off or on ?? and the power that your subs can take for 30secs

Its almost two 14k2e together its a pretty big beast

And guys the 4000 to $4500 this is retail price on it, if you are getting in a store If you compete and really need some extra power We have competitor prices, Just send me your info and I will let you know the price on it Please email to me ( jefferson@stetsom.com ) Name Address (house #, city, state, country, zipcode) Phone Email what amplifiers would you like to buy ? What car do you have ? What sub will you use and how many ? (specs) Box setup ? How many batteries ? How many alternators ? What class do you compete and Store name (if you have one) Your last score Pictures of the system Thank you

Well yes, if you think like this Instead of having 2 - 14k2e you can have only one amplifier that would make the same amount of power than 2 of them with the same amount of power consumption but you dont have to match gains on the amplifiers Well a lot of people are building 20000 rms system nowadays it would be the same power consumption of having 4 - 6000 rms amplifiers than one giving you 24000 rms Its just a better tool for competitor that needs a lot of power Multiple amps help fight rise..... Is this amp capable of performing without issue in a ground pounder or is it more for burps.... Well the beast was made for daily system, this amplifier came from the 35k2e that we have at 24volts we made a version of 18volts and is the 25k2e Im pretty sure 95% of these two amplifier that we sold were used in daily system for music, Stetsom amplifier are not made for only for burp, we sell thousand of amplifier in a month in brazil and all of them are for daily system

The amplifier can go down to 12volts But I am looking forward to do some tests on 12volts on it and the price is not that much REtail is around 4000 to $4500

thats price you can only get with me, if you compete Got show some proof that you compete

Im looking forward to do some test in 12volts on this amplifier after I get my test sample I will let you guys know

Hi there, The Stetsom voltmeter is not just a meter Is a power manager control you can turn on your amplifier on it and also monitor the lowest voltage and the highest voltage and its helps to protect your system

Here is more info on the amplifier just contact the guys here at the SSA and they will take care of you Venom 900.1 specs Venom 900.1 specs

please get in contact with the SSA guys support@soundsolutionsaudio.com they will help you out thank you

Hey there, im sorry for the problem you are having but you can not take the fan outta the amplifier I have heard some cases like this, something the fan get out place do the vibration and make noise, try to take a look at the fan and see if its hits something of if there is something on the way what it might work too is to change the position of the amplifier,

hey guys !!! Here is a test that Kettle from another forum did on it 1K5 H 1ohm, test bench. Top w are made with solid clip light. vol-----v--------a--------w-----battery----ohms 16----43,6----10,71----466,9----13,04-------4 17----49,1----11,84----581,3----12,96-------4 16----42,2----21,6-----911,5----12,73-------2 17----46,1----22,8-----1051-----12,65-------2 15----34,3----33,66----1154,5---12,54-------1 16----39,4----38,06----1499,5---12,32-------1 Thread about the Test i will do some test on my own with videos, i test my 1k5h already and i got 69 ac volt x 21 ac amps (1449 rms @ 3.28ohms impedance rise burping @ 56hz with two dd1512 144.7db I had a 1k5h @ 2ohms and the subs were at 2ohms nominal impedance voltage drop was around 12.9v This is what i remember, im never made a video, but i was testing before i was going to a show and i got impressed, i will never forget it, when i saw that 69ac volts on the meter !! and the amplifier is smaller than a sheet of paper pretty soon i will do videos Specs on the amplifier
