[@michaelhemric5228]

BigDWiz hey BigD just wanted to let you know that pandora is now doing podcasts aswell!!! Gotta get the 12vT in there man

[@recon440]

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]

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.

[@HighVybeTribe]

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

[@ROBERTJOHNSON-fj8rj]

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.

[@nbrowser]

Hey Big D, you do know it takes more of a man to admit he F'ed up than one that hides his mistakes, S$%# happens and you cleared it up and no one can fault ya for that. Keep up the good work. Granted the amp is still a 6 dressed up as a 9.

[@watup110875]

amen

[@Gustavoaa96]

Great video Big D! Stetsom is getting so much behind the other brands here in Brazil after many tests like this. One question, are you with another Brazilian amp in mind to do an amp test? I really apreciate your videos. Keep the good job!

[@volvo09]

If you haven't seen there's I think 2 prior Brazilian amp dyno tests... But these are interesting amps, I would like to see more!

[@ΑντώνηςΜαγκανιάρης-η9ζ]

I have 4 70w rms speakers i have connected to my radiosupply... Do you think that with this amp will play better than my 40w rms sypply?

[@Choralone422]

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!

[@wal]

I chip off the new block 😜

[@nickramnarine9838]

This amp does very well in the higher frequency because it was made for high frequency drivers rather than subs. As usual great vid. Keep up the good work.

[@NathanOakley1980]

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]

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

[@elviscordero4509]

I use those amps and they’re amazing, they’ll move anything

[@chris_vandepeer]

When i worked as a car mechanic i guy a knew had to clear a car for scrap and there was 2 of the rockford fosgate 12s in it.He came back with them and i asked what are you going to do with them......he said maybe i will put them in my car.2 weeks later i went over his place and saw them in the garden full of rain water.

Bid D., how old was this video? because I have the exact same Stetsom amplifier and mine only has six speaker inputs for a four channel amp. I seen yours and it has eight speaker inputs. But I watched Dean from 5 star car stereo hooked up one just like mine and it worked.

[@NordicDan]

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]

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

[@jr1001jr]

👍👍 for your integrity BigD ... you made things right. Salute.

[@iceman45ification1]

Not for nothing, but being that this amp is labeled backwards for bridged mode compared to most amps, makes it a bit confusing. Lol. Still though, it should be labeled as 50 × 4 @ 4 ohms instead of overating it. I wouldn't even bother with this amp with all the better choices out there for the price. Great video brother!! 👌

[@wal]

I agree wholeheartedly 🤙

[@mwestie12]

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.

[@alexvds1]

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.

[@wal]

👍

[@watup110875]

@WillistonAudioLabs good job correcting your mistake

[@mikeadams2677]

Ok. Since you're talking old school. I have a 1977 Ford LTD. I'm using a Sony CD/ BLUETOOTH $100 200 watt head, 2 6 1/2" Kicker door mounts in front doors and 2 Sony 250w 6x9 in the rear. I'm not using a sub, but want an amp for more power to run what I have, that I can mount hidden under the dash without cutting the car up to keep its factory look. Is this amp a good option on a budget or can you advise a better option for my setup? Thanks

[@josephhayden6358]

so im confused a little, what is your dyno measuring peak wattage output or is it calculating RMS? while running, i would imagine like a car dyno it'd look for peak but idk...

[@ChaosHusky]

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!

Use a similar amp (IR 280.3) for my daily driver. I use it to power a little front system (120$ 5,25" kit). A reasonable upgrade from the built in amp in the HU, and that with a sneaky installation.

You are the man big dummy aren't we all though 😁 I'd knew you would come through with a follow up.

[@303nitzubishi4]

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]

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.
