The Vulcan line they are Class D amplifier The 1k5h is the half bridged amplifier class D with 95 % of efficiency

I will do a post about the 4 channels and 2 channels amplifiers Take a look on the SSA store and they are there but i will make a post about it

I dont really get your question are you talking about the 1k5h ?? which has the half bridged technology >? Any of them..what are they switching at. You have a frequency in which the gates are opening or closing at..on the fets and/or transistors on the output stage (You can see this on an o-scope if you do not know, you just have to get in the range that they are operating at). The only amplifier in the world that is truly an amplifier is a class A, everything else switches via gates on a mosfet or a transistor..I want to know the operating frequency of that device. 100kHz? 120kHz? Higher? The smaller transformers and parts that are used the higher and harder the gates are being switched on fets/transistors..I want to know what this frequency range is. Well i understand now, i was just making sure its not everyone nowadays that ask me that for the power supply is 26khz and the to the channels (fets) is 104khz on the big models and for the 1k5h is 180khz and the power supply 26khz also but why this question ?? but what want to know this ?? :puzzled: That's what i'm looking for...this goes for the class D amplifiers as well, not just the H bridge? Would there happen to be any filtering done for this on the output fets? Please send me a email for the detail question i will answer it there better jefferson@stetsom.com

great update !!

Nice

More Voltage always equal more power. The two amps you asked about do about the same amount of power but have different features on them, so see which fits your application the most. The Stetsom does more power than the Sundown at 2 and 4 ohms as well. thank you to point that out, i didnt even noticed that =p

hello there, Im here to help out any one that is interesting on have stetsom on your setup Please make New topics about your questions Thank you

hello there, Well the 2k5e is a nice amp to compare to the sundown 3500 Well the 2k5e has a nice efficiency on his performance about 94% @ 4 ohms at 100hz sundown is 86% 90% @ 2ohms at 100hz sundown ??? 86 % @ 1ohm at 100hz sundown ??? well as you can see what sundown does in 4 ohms we do in 1 ohm =) 2k5e power consumption is 275ah max, sundown is 350ah ( i guess) and our amps are rated at 12.6 and 13.8 volts Channels: 1 RMS Power @ 13.8V Mono 1 Ohm: 3300 Watts RMS Power @ 13.8V Mono 2 Ohms: 2200 Watts RMS Power @ 13.8V Mono 4 Ohms: 1300 Watts RMS Power @ 12.6V Mono 1 Ohm: 2500 Watts RMS Power @ 12.6V Mono 2 Ohms: 1850 Watts RMS Power @ 12.6V Mono 4 Ohms: 1100 Watts sundown has a pretty good design as the 2k5e, but we cant really compare them because they are rated at different power and also the sundown is made to make more power, but the Stetsom 2k5e keeps up with him with a small difference of amount of power !!! and our amps are 12volts amplifiers, they dont need high voltage to make power, i would say anything more than 14.5 volts is not necessary and also our amplifier has a protection mode from 9v to 15v the 12 volts amplfiers are based on 12votls batteries you never should have a 12volts batteries up to 14.8 volts when you are charging it

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

I dont really get your question are you talking about the 1k5h ?? which has the half bridged technology >?

no problem, i will try to get a video with 19k2e with a subwoofer setup for you =p

thank you guys, i hope i can answer many questions !!! im going to make some posts about how to setup big amps and test it and much more to help people out
