Ok, so some big dummy wired the Stetsom amp incorrectly for the first video, so I decided to make a follow-up one showing it wired correctly for the Dyno test. Let's see if it can do rated wired correctly...

Hey love the videos. I think that what you are doing is awesome. It gives people the opportunity to see something preform before they get disappointed. Just out of curiosity. What amp from 2018 has surprised you the most? Also what amp has surprised you the most since you first started to test them? One final question. Do you have any concept amplifiers laying around? I would love to see what something like an old cc-d1200 could lay down.

@watup110875 8 месяцев назад

@WillistonAudioLabs good job correcting your mistake

@recon440 5 лет назад

Thanks for the test. An amp like this may put out some substantial numbers but will never put out the dynamics simply due to lack of capacitance. To use an example, it's like a head unit that makes 25w rms per channel (optimistic) vs. an external 25x4 amp. The external amp will have substantially better volume, dynamics and depth due to so much more power supply headroom (despite same rms power) where in the real world you are dealing with harmonics, rather than reproducing a single frequency.

@casey360360 2 года назад

Good luck explaining this to people though. I've even pulled a head unit and a 4 channel apart to show people the difference, head unit didn't have any capacitors on the output circuit, they just scratched their head and still told me I was wrong.

@Bobcatspiritdude Год назад

@casey360360 lol , that's some dedicated explaning ! Too bad it went over their heads ! . But we appreciate you here !

@ROBERTJOHNSON-fj8rj Год назад

Thank u for explaining this. I have a '14 Kia soul. Want to keep the head unit but just was looking for a lil more power without having to get an amp which will drain power when playing music parked at a beach or something. This may be the amp.

@Choralone422 5 лет назад

Thank you for the retest. While it's interesting to see someone make an unconventional amp I still believe it's not much more than a cheap chip amp. Being able to push bigger power at a higher frequency proves that IMO. Still, I think it's great that you owned up to the mistake and did a retest. BigDWiz FTW!

@303nitzubishi4 5 лет назад

Thanks for the recap big D. If only this amp was a bit more competitively priced I think it would come in handy for bi amping some front stage components. Wiring an amp up in the hatchback or trunk then having a long speaker wire run up to the doors always bugs me. Something more compact like this could be mounted much closer to your HU & front speakers. Can't wait to see what is going on with the Xplod in the background. The black X means mobile ES if I remember correctly eh

@uN1Qu3DZ 5 лет назад

I wouldn't expect much quality for an IC-based class D amp with lowest-end parts. My humble opinion is that it would do great for mids or door speakers, but I wouldn't run tweeters on that.

@Dget01 4 года назад

What is the difference in the wiring between the 4 channel 4 ohm and the 4 channel 2 ohm?

@NordicDan Год назад

I've just recently heard of these. While I have no intention of using one to power a subwoofer, I wonder how it would sound powering a pair of 4ohm 6x9 speakers rated at 90W RMS. The compact size has me very curious, as it would leave plenty or room for airflow and heat dissipation for the sake of longevity.

@kmother19 Год назад

I got one, the new model I belive. And it's powering a pair of tweeters on the front and a pair of 6.5s on the rear. They sound amazing on it. No complaints so far

Hahah.. Watched the first vid of course and noticed you had it hooked up slightly incorrectly but.. Well, i'm surprised by this amp! It's a bit crap and overpriced, but for the size, puts out more power than that little kicker! I'll try and do a video soon of this little Boss amp i have.. No wattage dyno but i suppose monitoring the input current will give at least some idea. I also have a hilarious "100 watt" chip type amp that's actually rated 22WRMS per channel due to the chip. It's worse than the chips found in most head units! Keep those tests coming!

@alexvds1 4 года назад

I've already used this amplifier, the frequency cut for subwoofer mode has a gain of 15 db at 45 Hz, it creates an absurd bass latency for the rest of the frequencies. I never use it for a subwoofer ever again, in Brazil Soundigital is a brand of excellence and Taramps right behind in terms of quality, Stetsom is known for making affordable products with lower quality.

@NathanOakley1980 2 года назад

4:00 Ace ace ace! Been looking for a video coving this for ages! And came across one by Jacob Virol. I’m asking you as you have an amp dyno and could see if my thinking is correct. Ok….here is my question: If you have 4x50w amp and you only use 2 of the 4 channels, does this mean you have slightly more power on the used channels given the decreased stress on the power supply?? The reason I ask is, in AV, they rate the multichannel amps with only 2 channels driven because when all channels are driven the output of each is significantly reduced. So, by contrast, if you only used 2 of 4 channels on a multi channel amp, do you get a bit more power from the amp?? This is not a question about bridging the amp, just about leaving 2 channels unconnected like when using an AV amp in stereo. If you were to test a 4 channel amp but *without* the dummy loads on the 2 untested channels, would the output for the used channels increase?

@wal 2 года назад

Yes I believe this is true as it would be less stress/load on the power supply
