A watt is a watt, or is it? - Tech Stuff Tuesday

[@EMFAudio]

Is cheap power worth it? I don't think so! What do you think?

[@ruikazane5123]

There are tons of amp dyno vids on KZbin. You should not look at the watts written. You should think about dollar per watt...

[@EMFAudio]

@@ruikazane5123 Did you pay attention closely to the video? With this particular instance, the higher the power got the more SPL difference there was. The extra "power" wasn't as effective, and that's completely ignoring sound quality differences. There is also the wave form differences seen in the video. You might watch this video kzbin.info/www/bejne/iqKxnaOuoL1rjac Also, amp dyno's don't consider efficiency (and they give unrealistic results because you don't listen to resistors on a bench).

[@ruikazane5123]

EMF Audio True, since amp dynos don't measure the passband frequencies, and that they use breaking resistors, not the variable resistance/inductance voice coil!

[@thebassgeneratorinc229]

Honestly cheap power or what evers brought to me to install? It's my job to use it in the most efficient way that I can. I understand that every one don't care much about status quo or branding but rather what they can get for their dollar. At time's, we only look thing's from one perspective and not taking into consideration of what others may or may not be thinking. Not everyone compete nor even car about competing, most don't understand that the street are the driving factors of ehy these products flourish as they do and they will continue to do so. PA for example, take away the boagus ratings and you have a product that perform quite well at the ppwer level that it end up producing, very reliable and takes the beating of a inexperienced user.

[@thebassgeneratorinc229]

this test would had been better if the SAE1000D was used in comparison in performance wattage and performance due to it being closer to the Boss true output. but to use a unrealistic approach of a monstrous 12000 is kinda one sided because its idling while tge Boss is stressing its power supply. But this is just my thoughts...I am not trying to create drama but rather a more optimistic approach to your efforts and comparison.

[@stankinsteinfrankfurter9005]

I chuckled when u said the words "boss 4,000 watt amp" lmao!!!!

[@TheoneDragon51]

Ya cheap power is worth it. My reason, a young kid just trying to get decent sound in his car, also has much higher fuel cost than we did growing up. But as an adult, most of us have more money to spend and some appreciate the better sound quality, that we get for our money. So ya depends on if your a kid or adult if your buying that amp. Great video!

[@thebassgeneratorinc229]

Dragon51 your analogy is far off basics, the diffference from a consumer andva dealer are as simple as it gets, people whom amplify the sound wants their music loud as they can get it. To me, sound quality is greatly misused...at what point does the human ear start to get fatigue and starts to be permanently damage? as a beginner (age has nothing to do with it) we tend to get as loud as we can to be heard from the outside of the car....Sound quality turns to Sound quantity. if you compete? the benefits is to a amplifier tgatvis better suited ofir your objectives but to a person in tge streets? its about being heard beyond the car and most any amplifier would do this job. this devate has so many variables but tge facts are that the streets are where the money is being made just like in many other format in this automotive industry. this is why tge major company's are offering watered down versions to enter this market, so do okay but other are still beyond what so would be willing to pay. Calling someone a kid for not havingvthe same objectivecas you is ignorant or just hateful thinking withoutvhaving an idea of what their objectives are....I am not trying to distespect anyone but at the same time, I am not trying to be disrespected either😊

[@finnirish12]

Or teach the younger guys to buy a cheap amp that's actually rated for that power. Like a taramps 4k. Its built cheap but it hits rated power. Boss is junk.

[@FATMIKED5183]

Honestly,spend a little more money to get a lot more quality and performance.Sometimes it's really not cheap to buy cheap stuff,because then you're not happy with it,and buy new stuff to replace it.So you were gonna spend the money anyway,shoulda done it from the get go.

[@imthirstyh2o330]

Next: thermal effects on voice coil from dirty un clipped power vs clean power

[@Bigshane90]

Would like the test ran while keeping both amplifier signals equally clean. I believe the only thing proven is introducing distortion lowers overall spl output per watt if anything. The very first test on the boss the signal is clipped, which skews the test. If you look at the ohm load you will see 4.4 and it does a 145.5. While the emf amp does a 145.6 at 4.7 ohms. Higher rise ussually indicates a higher peak spl. Even though the emf amp is at a clear advantage from the beginning, it won by .1. To answer the question of the video, yes cheap power is worth it. The mighty dollar per watt will always hold true. Even if we over rate your amp by idk 5k watts. So it produces 17k. It makes 7.7 watts per dollar. Take an audiopipe 2k and say it only produces the 2k but it's 180 bucks. It just made 11 watts per dollar. Roughly 40% better than what your amp made. So at 40% less money than your amp, audiopipe can produce the same power. So for the same money your amp produces 17k watts, audiopipe can produce 23k watts. Which one is louder on the meter then?

[@EMFAudio]

The problem is the amps will never be equally clean. The Boss amp is just dirty power. At 300 watts where the SPL difference was none, it was still just as dirty as 500 watts on the Boss amp. Every competitor knows introducing just a little bit of clipping is usually HIGHER SPL. Impedance being different between the two amps could be a number of factors, including but not limited to coil temperature from doing back to back testing. The sub wasn't cold starting with the 'Merica as it was the Boss. In regards to your cost per watt relationship, also consider the damage that will happen to your subs from that dirty ass power of a cheap amp. That costs you recones. What about efficiency? A 65% efficient amp vs an 85% efficient amp costs you more money in electrical. What about when you have to buy that cheap amp 3 times because they keep dying where the better amp doesn't ever die? Those are all factors in the end of the real cost per watt. For your specific example of Audiopipe I can tell you I've tested direct swap an Audiopipe and a Sundown amp, both 1,500 watts rated, clamping within 200 watts of each other, and the Sundown was 1 dB louder.

[@Bigshane90]

I'm not saying that there aren't other factors in determining which amp is better for your situation. I'm disagreeing with your statement that all watts are not equal. There are to many variables for it to even be tested accurately. A watt will always be a watt. Until the signal is manipulated. If the boss is in fact distorting the signal right off the bat, that's pretty crappy. But a watt is still a watt. By the way I don't see everybody running cheap amps blowing there subs all the time lol.

[@EMFAudio]

@@Bigshane90 What variables do you need beyond power output and SPL reading? That's not subjective, that's data. The signal is manipulated by the amplifier, being dirty. Yeah, it is pretty crappy, and that's the point. If you don't see anybody running cheap amps blowing subs, you aren't looking. I see it all the time. Audiopipe and Shark (same amps) are leading causes of it. I can guess that's what they're using before they tell me. Brazilian is the same way.

[@tmatthews0007]

Bigshane90 haha bro. Emf is mad because you hit with some economics.

[@thebassgeneratorinc229]

food for thought, the quality of the amp have a big effect of the performance of gge product but the power level are great but tgeir are mkre voverning factors that determines what a amp does in other criterias that allow it to keep clean at higher power levels. your poi t is a string one but honestly, to a novice? price is tge determining factor. this is why companys as this are still around today and doing quite well even with the bashing. as a installer, my job is to get the most out of whzt evers in front of me because a few of tgese people will wa t to do better later in life but until then...its a learning experience that eill make or break a beginner.

[@justingillette8287]

This video is a total waste. You can’t compare an amp that you force into clipping against a huge unit that is not and say that one pulls more watts to spl output than the bigger unit.

[@EMFAudio]

You can compare, because I did. Take note, not every time it played was "forced" clipping. It's a dirty ass amp, all the time. At no level did the Boss show a perfectly clean signal. Did you watch the video? Maybe this one will better explain what happened. kzbin.info/www/bejne/iqKxnaOuoL1rjac

[@charliefrancis6438]

I like the science you are using 👍🏻

[@vincentrobinette1507]

I couldn't help but notice, the current signature being much cleaner once connected to the higher fidelity "Merica" amplifier, same driver, same enclosure. I've tested this same driver,(dual 2 Ohm voice coil) and found, that the driver isn't designed to deliver the high harmonics associated with clipping. More power, no more sound. Big drivers, with heavy moving mass really do prefer clean sine wave, or, with music, avoiding harmonics above about 400 Hz. Clipping introduces harmonics, this driver simply isn't designed to reproduce. Big amplifier, low crossover point, keep it clean!

[@3RDERA]

Awesome video 🤟 Quality always performs better. ONLY situation this boss amp is a good value, is someone wanting to dabble in competing like the D.B. drag stock 1000 class, to see if they like the overall aspect of what it takes to compete; Box design, making car efficient, and just seeing if competing is something they enjoy doing. With that being said.,Spending 110 bucks on , in this scenario, a throw away amp, that you’ll end up replacing if you end up wanting to get serious about competing ,to at least last a few burps and get you anywhere from 500-1000 watts , is worth the $. Where if someone wants to try competing for the first time ,spends 300+ on an amp and about the same on subs to find out they don’t enjoy the craft of competing, and never use that equipment again, it would be a waste of money. But I imagine you could argue that you can sell that better equipment afterwards since it would be decent quality on the used market and make some of it back. So it’s tough to say in this specific scenario. Emphasis on this SPECIFIC scenario. Overall, I couldn’t agree with you more on buying cheap junk expecting the same results as quality gear.

[@thebassgeneratorinc229]

I agree the it is very wise to do your home work before looking at number, with social media being as it is, one ca. find examples of a product jn question and see how other use them. tech pages as this lne are tbe best at learning the ins and outs of car audio. It would be a very good thing if all manufacturers would do this. keep up the great work and I look forward to more of your tech briefs.

[@EMFAudio]

If all manufacturers did it, some would go out of business when people find out what their products really are.

[@xenaguy01]

Why didn't you do this comparison with a SAE 1000d?

[@EMFAudio]

I didn't have any at the time, and it would add more time to put the video together for no benefit. Don't worry though, I do have a video planned with an SAE-1000d though.

[@likeclockwork6473]

That Boss is really only a 700-900 watt 1ohm amp depending on your voltage. Not bad for the $110 you can pick them up for. I bet the Pioneer D9601 is cleaner. That would be a good amp to look at too. I know compared to the high end stuff $50-$60 is peanuts but when you are talking performance per dollar comparing a $110 amp to a $170 amp, that's a significant difference, especially when those dollars go into better electrical, build complexity, and quality of the enclosure. Sure, not when you are paying a "professional" to do it but if you are doing it yourself and your budget is really constrained, $300 or $500 is far better spent on the rest of the system instead of just amplifiers and drivers. The driver does matter and the amplifier matters even more, but your enclosure, head unit sound quality, and sound deadening in the car can be just as important to how your system sounds. A shitty sound file will still sound awful when played through an exceptional system.

[@EMFAudio]

The notable thing about the price differences, the lifespan of having the product. If the amps don't last you spend more money buying more amps. If the amp is inefficient as the cheap ones often are, you have to spend more money on electrical so you still ended up spending it. There is also the point of clarity. Even at 500 watts this amp wasn't clean, sound quality is definitely a factor which you get with the better amps. That Pioneer amp is a $300 amp, I would expect it to be better than the $110 amp. Funny enough, you could spend less money on a Sundown SAE-1000d and get a better result than the Pioneer.

[@likeclockwork6473]

@@EMFAudio The Pioneer GM-D9701 is only $180. It would surprise me if the Sundown wasn't stronger and cleaner than the Pioneer at that price. The alternative to the Pioneer would be whatever JBL is replacing the GTX 500 with. Prices will probably be high initially (around $150) but they get closer to $100 fairly quickly. Similar power to the Pioneer at 2 ohm but I bet the signal is cleaner. As for life expectancy I've never seen published results for any of these cheaper amps' failure rates. It would surprise me if the Sundown didn't hold up better but I've never read anything factual on the matter. Kind of why I'd be hesitant on picking up those new Hifonics amps. When you are spending $250-$300 for very high output equipment, if there was any significant difference audibly and in longevity, I'd consider biting the bullet and getting those $500-$600 Sundown and Banda amps. For me personally I wouldn't be running any of these amps hard. All of this stuff has sweet spots in terms of efficiency and stability. Same thing with computers. Just because it can run harder, doesn't mean it should. Sacrilege for burp fanatics I know but for just running a system in your car that gets audibly loud (loudness is subjective) I don't see one of these cheap amps really being the Achilles heel of a clean sounding system. Your mids and highs should really run on clean amps but I wouldn't go as far as to say you need Focal quality to sound clean. A clean signal feeding into even these mainstream amps will sound good enough for even most enthusiasts. Some of these $3k-$5k system I've seen are ripoffs. No imagination what so ever, just fine tuning, staging, and timing.

[@EMFAudio]

@@likeclockwork6473 You originally said 9601 for the Pioneer. I've never seen ANY amp have a published life expectancy.

the waveform display confuses the hell out of me, all of them look pretty nasty tbh. i've become a big fan of having headroom in my equipment. i'm still budget orientated with what i can buy, but have found that having a little patience to allow for more powerful equipment is worth it, even if you aren't "using" all of it. there's no shame in running a small system while you save up for a good system, but be saving up for that good equipment. and for the love of god, DON'T NEGLECT YOUR ELECTRICAL!!!! idgaf how many batteries or super caps you have, if your alt can only generate 100 amps of usable spare current, don't try to pull more than 100 amps from the system. good solid connections and a good solid electrical setup is the foundation of good clean sound.

[@EMFAudio]

The waveform isn't capable of getting the kind of line you're thinking of. There aren't enough data points and it's not analog. A clean wave zoomed in that far makes it look how it looks. But, if the peak is chopped, it's clipped a little.

Really interesting video. There really has to be some sort of over view and standard of how amps are rated. Keep companies from rating amps ridiculously high to basically scam people who dont know much about car audio. They don't necessarily have to put in car numbers but at least the true dyno numbers. Lol it's basically fraud what they are doing.

[@johngutierrez4882]

Cea 2007

[@EMFAudio]

CEA-2006 rating was supposed to remedy that. There are 2 problem I find with that standard though. First, you aren't required to adhere to it, so having it is more of reassurance for somebody who is aware of it. If they don't know, it's worthless from a consumer standpoint. Second, the standard is still kind of vague. It requires the power stated at 14.4v on a resistive load, with no more than 1% distortion. That isn't in car, that isn't across bandwidth, it's not even an average of any aspect. Most cars wont' have 14.4v during play to start with. Dyno numbers are almost as bad as CEA-2006 ratings, but better than "we'll just put a number on it".

[@jamest.5001]

The cleaner the power, the more effiecent! The sub doesn't do any work on DC voltage! That sine wave is basically exactly what the cone is doing, if the peaks are clipped, the sub has stopped moving air effectively! Just like running full range signal to a sub, it will do better low passed,

Watt is a watt. But then you have signal to noise which plays a factor in over loudnes. Or am i wrong?

Signal to noise is just the ratio of what you hear to things in the background being heard. I think what you're thinking of is THD.

[@altypeRR]

They don’t give give RMS because it doesn’t look as good if you say an amp can continuously give X. It sells more to say it can give a split second of Y power. I’m guessing what your measuring is RMS power?

[@EMFAudio]

RMS power is in fact what is being shown on the screen.

[@altypeRR]

That’s what I wondered but wasn’t sure.

[@tmatthews0007]

Ok so I wrote down all the numbers for every burp. The only time there was a significant difference in dB between the two amps was at the 900+ watt range, which is of course when the boss is stressed to put out the power while the 14k amp isn’t stressed at all. If you follow that finding logically then you can assume a watt is a watt as long as you aren’t “redlining” the amps capability. But Until we get amps that are close in output capability but drastically different price ranges we can’t know for sure that it makes a difference in the lanes. Sound quality is of course a different story all together. Please keep up the good scientific work.

[@EMFAudio]

In the lanes is exactly where it showed. That is where you're counting every 0.1 dB, and the Boss at any level was at least that down. The greater the power level, the more it was down. The loudness isn't audible, but it definitely shows up on the SPL meter.

[@tmatthews0007]

EMF Audio the boss performed bad at 900 watts because it was struggling to make 900 watts where as the emf amp can do it without trying

[@tmatthews0007]

EMF Audio the experiment here is a fail because the amps aren’t even close to the same rating. Try a sundown 1k vs the boss and see if there is a difference. Shouldn’t take too long to prove you’re right then.

[@EMFAudio]

I don't think you understood the test at all. It doesn't matter if they're the same rating. Why would I try a Sundown 1k when the Boss is a 4k? Shouldn't I use a Sundown 4k then? The point was, the power you see isn't necessarily how it will read on an decibel meter. The data showed at 500 watts the Boss showed a lower SPL, 600 watts the gap got bigger, 700 watts, bigger, 800 watts, bigger. Are you saying the Boss is struggling to make power at 500 watts? At literally every power level above 300 watts, the Boss showed a lower SPL reading and the greater the power increase the greater the gap. That is what was being discovered, not how much power does it make compared to another amp. At no point was the Boss at more than a slight clip, had I really hard clipped it SPL readings would have been way down and power would have been way up.

[@tmatthews0007]

EMF Audio no you wouldn’t just use a sundown 4K because we both know the boss is actually a 1k on the inside. I followed every score. The differences were tenths of a dB. To make up for it you could very well just use a bigger cheap amp to make up the difference.

[@99Duds]

Common sense goes a long way when looking at amps to buy, you should always look for specs on the box and if you only see max power rating its prob not true. They could be referring to how much power in watts it pulls and not the out put of the amp.

[@EMFAudio]

While you are correct about only listing peak power, if it says the power on the amp it's usually not accurate either. I don't mean in the model, I mean where it clearly states the power in watts.

[@dnlpnd]

I've never understood, why a slightly clipped signal burp is often louder than a clean signal burp.

[@EMFAudio]

The extra power can add a bit, but I think it's more related to the flat top on the wave being enough to prolong the average of the sample but not enough to go into power compression effecting the sub or hold it in a state of throw for too long to delay the average.

[@adissabovic]

Analytics don't keep up in real time. I have videos with hundreds more views than show on the video itself till hours later.

[@volvo09]

Yeah, KZbin analytics are slow and show weird on fresh videos.

The Boss would do 2000watts at 1 ohm because it did 1000w after rising to 1.9 ohm

[@EMFAudio]

The only way to get it to play at 1 ohm would be to wire it below 1 ohm. You don't listen to resistors, this is a REAL test. Cutting the impedance in half doesn't always translate to doubling power either. This is evident when wiring to say, 0.25 and playing at 0.5 on a 1 ohm rated amp. Additionally, this amp has 120 amps of fusing on the amp. Assuming an absolute best case scenario of 14.4v and 100% efficiency (which it won't) that's only capable of producing 1,728 watts before fuses blow. Even assuming an unrealistic 85% efficiency like you get in good amps, that's 1,468 watts. Most cheap class D amps are around 65-70% efficient, so you'd be looking at about 1,200 watts which was my guess of what it could do.

@@buddean8186 It's 8 gauge wire, a very short run. If you think it will do 2,000 watts easily, prove it. The fusing right on the amp says it can't do it or it would blow the fuses. 120 amps of fusing on 18v with 90% efficiency still isn't 2,000 watts and we know it's not 90% efficient and probably won't work on 18v.

@@buddean8186 I'd get the same results. Yeah I could put the big amp on that same 8 gauge wire and make that same power it did. Voltage wouldn't drop because current draw would be within the wire limits. 100 amps of draw is 100 amps of draw, it doesn't matter if it's a 1,000 watt amp doing it or a 10,000 watt amp doing it. You might doubt it clips because it's a junk amp, but that's why you do what you do and I do what I do. I backed up what I said with the tools that prove it, whether you want to believe it or not. You're arguing with science.

It sucks they lie sooo bad! That 4kw is the if struck by lightning output, while in a Delorian going 88 mph!! That's the only way to get that out of it! It didn't even do 1/4 rated, maybe 1/5, they should call that a 600-900 watt amp, and that's kinda pushing it! Still over rated! They was a 800 watt pyramid amp tested, it did about 63 watts dynamic, stuff like this is straight up fraud! I'm all up for cheap amps, but it should atleast do rated dirty. Dynamically, If that thing did 4kw, it would probably catch fire!! Ha-ha!! Those amps have their place I guess, maybe connected to a pair 15" in a teens first ride. I had a boss ava600 on two kicker impulse 15's it did OK, about 125 per, it wasn't in there long, keep at it!!

[@user-un1sh8xh5v]

Damp only got like 800 watts on a dino video LOL things a piece of s***

[@likeclockwork6473]

800 watts for $110 is pretty impressive considering amps that would do that power in the mid 2000s were at least double the price

[@charliefrancis6438]

No real difference, except sound quality, and more $$$

[@EMFAudio]

There is a measurable SPL difference, reliability is also a consideration.

Dirty clicks!
