There are many ways to explain it, the most simple way is that audio amplifiers have set (user set for most car and pro audio) voltage gain. This means that the amplifier will put out a fixed voltage for a varying impedance load. The only problem is that the power supply has to work harder as you ask it to provided more current, and this usually ends up with a slight to large drop in voltage. This why the power never ever really doubles as you halve impedance, it may come really close, but won't most of the time...
If anything, no amplifier will ever produce more than twice the power at half the impedance. That simply can't happen in the operational bandwidth (audio range) the amplifier is intended to operate in... Some amps may limit output power (some JLs) and they may make you think that the amplifier is putting out the same power at all impedances, but in reality, they are just limiting the higher impedance output...
You mean lower, correct?

I'm running a 14 volt system with three xs battery's my alternators are turned up to charge at 15.5 so electrical is not a problem.. I clamped my new 20.1 by itself and it puts over 2500+watts so if I run these amp independently at two ohms on each subs I will only get about 1000w on each sub
2 independent amps put out slightly more power than 2 strapped given same impedance.
2 dual 4 ohm subs. You can only wire to- 1 ohm or 4ohm logically.
If wired at 1ohm, that would be either 2 ohm per amp or 0.5ohm per amp strapped.
If wired for 4ohm strapped, that's 2 ohm per amp strapped or independent.
If you are trying to wire each amp at 0.5ohm, get different subs if you can't ever strap them.

Sounds like you shouldnt so dont.
There are more cons to pros for strapping and until some company starts utilizing protection features specifically for strapped applications, it's never necessary to strap amps.

I have no idea what you just said...
IT looks like you said if you turn it up to 35 that 1\4 gain on amp it clips..
But if you lower the volume, it doesn't clip..
IF that's what you are saying.. then.. that's common sense but i am hoping you didn't mean that because i can't follow what you are saying.

As suggested, I'll start my post with the test's uncertainty. I've carefully calibrated each piece of equipment and considered every link in the chain and have come to a +/- 10,000w margin of error. That's close enough for a Podunk bass head like myself.
You guys keep saying "clamp" test. I assume half of you didn't even open the thread so I'll assume that half thinks it is a "clamp". Some of the rest of you might just be using that term to describe any "useless" end user's test of an amplifier's output. But for those who didn't read it or don't know, I used fixed resistance so that the voltage and current are in phase. As was mentioned...measuring voltage is pretty simple. The uncertainty of a simple (yet expensive) voltmeter is certainly nothing a hobbyist and others like him would consider bad enough to completely disregard any and all results.
With that said... I understand where you guys are coming from. I really do. But good lawd. How do you guys get out of bed in the morning before you validate the structural integrity of the floor using highly calibrated sonic something or another that's calibrated by something or another? Sheesh.
I realize that people use my results to make decisions or start arguments or whore them out. As such, I don't take them lightly; but at the same time... I don't get paid for this shit. This isn't my job and the onus of uncertainty is on the reader. Not me. I do the best with what I have and share my results. That's it. If you don't like or agree with my results, then do the damn tests yourself. Or ignore them. If you can't use the information in a responsible manner and with an appropriate number of grains of salt, then don't read them. Or if someone uses them, just say ol' T-Fade is a crackhead and move on with your life.
I'm just a dude. I'm not a scientist or engineer or even employed in the 12v industry. I'm an end user with more and better tools than most and I happen to be an amp whore. But I'm also an SPL competitor. So the only number that I *really* care about is the one on the TermLab. if I test an amp and get 3,000w, that power will do a certain number on the TermLab. If I test another amp and get 4,000w, that power will do a higher number on the TL. Consistently. Now.... does uncertainty matter here or does it matter that the "real" power is actually 1,473.245 watts and 1,732.436 watts? Nope. The one with more power was louder. Period. I've never, not once, tested an amp that made less power that was louder than another amp that made more. If my methods are so flawed and uncertainty so bad... that margin of error would certainly have shown itself by now because I do a TON of testing. But I suppose that could be coincidental. And I'm sure the TL not being calibrated just drives y'all nuts anyway.
Anyway... the one thing I hate about my testing is not *knowing* the THD. It's objective and open to interpretation the way I do it by just showing and reading the wave. But most people with the faculties to log on to the internet can distinguish between round and square. People can judge for themselves. Because I promise... your subs will tell that tale.
While I'm on a roll with anecdotal evidence... I tested an amp recently using my "useless" method, flawed objectivity and incomplete or lack of understanding of metrology and the scientific method and shared my results with the owner. Then, he shared with me the end all, be all test report from the manufacturer of the amplifier using their trillion dollar machines and what'dya know? They were awfully similar. Within 3%. But hey... maybe I got lucky on that one.
About the OP... I'm sorry if you don't like the 80.1's output. I REtested it again today and got extremely similar 12v results. The only variable being +1vdc. The large disparity between "clean" and clipped is interesting. It makes a shit ton of power dirty (but useable). Your subs will hate you, but the power is there. I also tested it on 18v and the output scales up really well. Doesn't change my results or opinion of the amp from the original test, but it's nice to know my meter didn't catch any uncertainty gremlins overnight.
3% is absolutely unacceptable, I'm sure your ears can pick up the difference...
I was unaware people did "clamp tests" to measure the possible measure of power that can audibly be heard as a difference compared to the rating on the box.
IF that were true, then clamp tests would be the best method.
That means as along as the 9,600w amp can do +/- 2,000w, then it's fine.
That's your implication. Seems irrational to me.

When you say you need to get them to make you some 65mm one way soft parts, that's specifically for the MMAG, correct?
And... is the finish production of the MMAG going to have 2 slugs?
And for me and all of us.. can you explain the difference between these-
MMAG vs Trident

Anyone happen to know what this sub is?
It appears to be one that is driven by electrical power in the form of AC converted over to mechanical energy to produce a or a range of sound in the lower portion of the human audible spectrum.
That should narrow it down some.

We are going to be having a group buy this month and into next month and we have an amp that would suite your needs.
It's rated to do 3,000w @13.8v, 2,500w @12.6v
Normal pricing is $469
Our Group Buy pricing for this amp will be right around $400 shipped.
Ship date is in early to mid March.

I don't think he got that model.
The TS400x4 is the one listed on the other site.

You are getting very close!
Now the only part is to understand that you cannot negatively comment on the amp's proposed poor performance from the test because it's currently impossible to tell that from the test. Especially since it was retested at 14.6v, with uncertainty, and jumped to over 10,000w.
Point is.. like u said, to give a general idea.
And the funny thing is, many people think, tought or believe the uncertainty tested result from test 1 is so far off from rated power that it's impossible to prove it's proper rating.
Nope..
I hope everyone has learned not to trust these tests as facts especially from the drama of this particular product.

Since everything was done wrong even though none of claim to have read the review, please enlighten us as to what he did wrong? .9 volts is not going to net you another 2k+
Like I said, I'll wait for the retest.
But, but, but, it didn't do rated. It has to be flawed....

Because you disagree with them doesn't make you wrong or a douche but changing my words around makes you a douche dumbass. But they have proven themselves to be very knowledgable and are definitely not stupid people one bit.
Only reason I said you were a douche was because almost the whole time you were just fighting with everyone and being sarcastic instead of trying to understand their view.
I understand their view, and their concern is not legitimate in this case, in my opinion. The results may not be 100% precise, but they're accurate enough for the purpose they serve. If you require an amp test to be accurate within 10 watts for your personal use.... so be it. I don't.
You're the only one name calling here...
So you think it's just barely off?
For one, the testing method is not consistent. Like others have stated before, it's used for TROUBLESHOOTING, not for proper power measurement.
Second, did you know it was recently retested by the same person and now it's went fro 13.5 to 14.6v and gained 3,200w? Now it's over 10k clipped.
People are "guessing" in that topic as to how much THD that is..
Bam- guessing..
that method of measuring power is for troubleshooting. For accurate results, testing must be consistent.
The 2 tests are not consistent and not controlled due to human error and the lack of THD measurement.
You can't state you obtained a certain amount of power without other factors.
Tfade has not done anything wrong to defer his measurements.
It's the lack of knowledge the audience has that concludes what they think they obtained from that information.
The same thing goes for many SMD devices as well but don't get me started on that.
So the measurements show a lack of output power.. Well.. that's not right..
Test again.. now we have massively increased power...
Lack of consistency and other measurements.
Tfade isn't trying to replace proper means of measuring with a low cost technique.
He's basically just trying to see if the equipment holds true to it's ratings.
The problem is messing with amps of this caliber is not easy because the higher the numbers go, the greater the inconsistency in his testing method.
The audience should take THAT as a big potential problem that is hard to control.
Even on low power, his method will net him closer to actual ratings but still not concrete enough because of a lack of tools and technique.
A power rating consists of a lot more than just 1 power rating with a voltage and a THD rating and not even those 3 things have been met in sync in one test yet.
Like i've said many times before, I defer to the manufacturer's testing themselves as they are more equipped for the task.
The second test was to prove a point... To get the 10k that people claim out of the amp, it was clipped to hell and back. The first test was "around" but not exactly at the THD rating that the manufacturer gives.
I guess we have to throw something on an amp dyno to make you guys happy.. lol
So, all other tests done by anyone in this aspect was not to prove a point?
Every test is to prove a point however inaccurate it might be.
And nothing is making us unhappy.
I personally do not care about the output results because i know because of inaccuracies, the results are pointless.
That's why i do not comment on how good or bad so and so amp is.
What I may comment on, like i am here, is the lack of understanding people get from the numbers.
We can go about this this way too-
on SMD a while back, someone dyno'ed a 5kw amp on the burst setting and it put out over 9k.
Just that alone went on for weeks and weeks across forums about how awesome the amp is.. it can do 9k, etc..
In reality, that test is not to test output but headroom potential which is another debate that i am not a fan of either because the reasoning makes no sense.
Then many people across the forums finally begin to understand how worthless the test is when you see how an amplifier is actually used.
This is the same way.. It's going to take a while for it to dig in but once people understand that testing must be controlled on a level that is not done here, then results are for troubleshooting, not for obtaining the ratings themselves.

Yea, the Massive Audio Hippo subs are the "largest subs" in their classified sizes that i've ever seen.
So large, that no other sub i know of can replace their cut out requirement.. and even the 15 isn't 15" or more in cut-out diameter.

lol.. Nick? no..
It sounds like you do not know IA well enough to say that.
But by you saying that.. it sounds easily like you care less what IA says in their upcoming retest just for the hell of it.
So i'm done.

you are still missing the point.....
You keeping siding with his testing as being accurate.
Let me ask you a simple question.
Why would you trust a person in this hobby who loves it as much as anyone else to perform a test on an amp, and regardless of the results, believe the results over what the manufacturer is about to present?

Like I said, I'll wait for the retest.
But, but, but, it didn't do rated. It has to be flawed....
But but but.. the owner said he will retest because all testing prior to marketing is correct and will retest..
However once he said that.. many people started bashing the "potential" for his other products to be flawed, etc..
I only trust the owner and\or companies who do this for a living.
If one person can be trusted to "fail" an amp publicly, then all companies might as well shut their businesses down because you know what they say..
The customer is always right...
So professional testing must be pointless..
We don't care about getting close
We, as a business community, care about doing it right.
Why would a business rely on a customer's test as the official ruling of their products potential.
That is the dumbest thing i've seen this year so far and that's pretty damn bad.
But keep supporting the "close testing".
We'll support professional test results.
