    Okay Im really interested in buying a 7KD but I have a question. First off a 1/0 gauge cable can only support 300-350 amps of draw yet your amps is pulling almost 800 with a load?

    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

    is a 5k2 pushing 2 fi btl 18 good for a daily setup

    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 !!

    I'm looking at getting a 14k2e and was wondering if these can b ran @ 0.7 ohms daily on the right electrical. Or is it just safer to run at 1 ohm daily. I'm just looking for as much power as possible and seen under 9k clamped at almost 2 ohms rise. Thanks for any input

    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

    On the older stetsoms how is the board attached too the case? And on the new ones how are they attached to the case? Also do all stetsom amps too rated power?

    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?

    Is there anyway to run these at 14.8v+ ?

    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

    oh damn...

    haha, that's 20 batteries in series i would assume, yes?

    20 rest at 13v = 260v..

    Interesting enough... maximum non clipped current draw should be less than 200A, yes?

    less than 200A is awesome.. but.. i have a question.

    What exactly is the reasoning in using a power supply that needs 24v or 240v on some of the amps?

    The battery requirement would still be the same...

    If i had an amp that put out 20,000w @12v, let's say i used 20 G31 batteries.

    Now, if i had another one put out 20,000w @24v, i would STILL need 20 batteries, just 10 pairs in series.

    Same output power, just half the current output..

    Is the purpose to save the customer money on the amp cost somehow?

    Does it make the amp more efficient somehow running that high voltage?

    I've been wonderin this for quite some time.

    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

    Well.. from past dealings and talking with others.. we all agreed that is how we were treated.

    Interesting now how i am being told the complete opposite.

    Well then.. since i brought up the 45kw amp.. you mentioned not everybody knows how to install a 240v amp.

    Simple assumption is you are referring to AC voltage...

    AC runs on the outer part of the conductor being used..

    Now, without doing any research on it, what is different about wiring the outputs on this amp?

    Does it have something to do with not being able to use stranded wire?

    they have a 45,000w amp too but unless you meet their standards.. u can just sit there and drool all you want because they are very picky at who qualifies to run their equipment.

    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

    whole lot of batteries and alternators!

    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

    Holy hell that's a big bitch.

    I would assume around 18-20k at 12-14volts. Unless the amp is designed to make power at 16-18volts only.

    I like the 8ohm rating. You don't see that much.

    I would hate to ask price. :( Its probably more than I paid for my first car.

    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

    There's a dealer in the Houston area close to Baytown.

    I was wondering how much do the Stetsom Voltmeter's cost.

    I need one and they look awesome :)

    Thanks!

    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

    Still nothing on the fan?

    Its been a great amp. But it's embarrassing when I want to show someone my system and this noisy ass fan is heard when the volume is low. Its really bad if I want to drive with no music and all you can hear is this annoying fan in the background.

    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 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...

    So is this Stetsoms offical online forum or what?

    because C a C o claims the same thing

    Hello there,

    Im sorry for the delay,

    well SSa and C a C o both of them are really good forums that you can get you questions answered

    But SSA will be the official in the future, not official yet
