See now this to me is where it gets interesting. Now since you are posting a cheaper alternative people have choices. From the clamp tests I've seen people do it's a dmm and clamp, this is my first time seeing a scope or true rms meter for such a low price. Still comes into factor of how well the user can see clipping on the scope.Velleman HPS140I 99$
Craftsmen clamp meter 72$
Fluke 113 true rms meter 116$
Sorry just under 300$ and you can clamp your amps power for efficiency as well as many other tasks you can do with these three items vs the AMM1.
It would be nice to see a comparison of equipment like what sintorman posted and the amm1.

Unless the amm1 is cheaper than 250 bucks then it's actually not the better deal. But if you honestly need something that can measure taking into account for the power factor then I guess spend the extra money. 99% of people don't do it and so the industry standard is basically clamping for voltamps.
That's what i'm trying to say, with cost difference between the tools needed to get an accurate test the amm1 is a hands down winner.
You are looking at about $5000 worth of testing equipment sitting on my make shift bench. I have the tools to do the job correctly, most people dont.thank you cj18, that's what I was trying to explain with my last post but you said it much better.
in short what im seeing is that with out the proper equipment (which gets expensive just for a good scope) you cant get an accurate results from the clamping that most people do. it can be a more accurate test with the right tools at hand and more work but for the money the amm1 is a steal.
all the scopes ive seen run around $300-400 for a nice one. don't forget the dmm and getting a test bench together to put a reactive load on the amp to get a true rms reading at a given load.
The AMM1 now provides an affordable solution that.
Yes clamping with the right tools can give you More accurate result but still not 100% and not as cost effective. Let's face it us audio guys are always looking for a good way to save money while still getting the install done right. The amm1 helps do that plus some with ease and accuracy.
Sorry if anyone feels like i'm baking clamping, not trying to. It's the way of the past and inaccurate compared to the amm1. For a cost effective tool the amm1 is a steal.
If the Fluke meters are used with an purely resistive load (99% of people do not have this), and you can guarantee that NO CLIPPING occurs then the AMM-1 and clamps should agree. So you need a True RMS Voltmeter, a True RMS clamp meter, an oscilloscope, and a non-inductive load bank. So basically an Amp Dyno. Add a zero to the end of that $250
Thanks Tony, the price for an accurate clasp test is a lot higher then people think. That price is much more the the amm1 and the amm1 is an all around helpful tool for car audio at a small% of the price for an accurate clamp test bench

An accurate clamp meter is 400 plus. Not to mention dmm and scope.

Amm1 is 460. Find an accurate clamp dmm, and scope for under that price. The clamp he used in the vid is over 600 alone.

but he also mentioned that if there is anyone that uses tools that can do what he did in his second test it would be hardly anyone. most people don't have the tools to do such an accurate test to get more accurate results. that being said. 99% of people are not getting a true rms reading because of not having the correct tools from what he was saying.
besides even at a 570w result in that test its still not accurate. still proves that as of right now one of the most accurate ways is the amp dyno or amm1 and you helped prove that.
-
^^ please explain how its misleading if you are so smart.
they come in here and post videos with facts supported by science and math while everyone else comes in here saying well clamping is how everyone does it so it must be true. that's like saying everything you read online is true or the well my brothers friends sisters boyfriend said this and so it must be true.
sorry but facts are facts while all that other stuff has no supporting science or math behind it.
-
so different amps/setups will have different % of difference between the dyno and clamp method right? or at least I would think it wouldn't always be a difference of 34.5%.
just asking that so people don't see the vid and say o well if its only a difference of 34.5% then I can clamp and subtract the % difference to get the true rms. I could see that happening.
great video once again though. glad you posted this meade, I didn't see the other thread so works for me.
remember everyone, haters will keep on hating. some people are most likely seeing these vids about how clamping doesn't work because of its inaccurate results from the lack of actually understanding what they are doing imo are just upset because what they thought their setup was putting out isn't what the true rms output is. people don't like being proven wrong or told that the excepted way to do something is inaccurate and a thing of the past.
I say let the haters hate while the rest of us thrive off of their hate to achieve better. I know when someone tells me I can do something I do it just to prove them wrong.

^^ to much time on your hands to go through and check that lol.

that some real power just off batts.
-
-
well that explains a lot n8, didn't know that.
but yeah I figure at 16v it should be close to 9-11k most people (including some of my guesses) are in the high 8k range. considering power draw and only batt powered though im hoping voltage drop will bring it down to my guesses lol.

we need a mod in here asap. im seeing a lot of first time posters that seems like someone might be making multiple accounts to better their chances

I didn't see anyone answer the other question yet so I will
yes, we like this guessing games. with or with out the prize it adds fun to the wait for results. the prize just makes it more exciting.

^ you can find their stuff at Wal-Mart now, doesn't that say they aren't trying to keep up with other brands?

More!!
Want ti see the Rockford booth.

just contact mechman and talk to them. they can make one for you that will be a direct swap no extra parts or anything needed. do the big 3 though, it will help a lot.
I have a 03 zx5 to and the alt is can be a bit of a pain to get to. move the power steering reservoir, coolant tank, after getting the alt unbolted either you will need to jack up the engine mount or use a pry bar on the passenger side motor mount to push the motor over a little bit to squeeze the alt out.
either way though just contact mechman tell them what your goal is answer their question.
imo, get the biggest one they offer. better to replace it once then twice. all bass heads upgrade eventually so get what you can now.
-
where are the links to your coverage and vids?
-
no...it's not a DD-1 at all.
Lol, read the post wrong.
-
dmm paired with a handheld amp dyno packed into a dmm case?
check voltage, check resistance, impedance, real world power, plus more. Should sell real good.

Rockford will always have online dealers, they are just cutting out the non authorized dealers as much as they can to help the growth of the authorized dealers and stop the non authorized dealers. non authorized dealers don't get the Rockford warranty and so either they can provide one themselves or their customers will be out money when they get a defected sub or blow it with poor knowledge of how to set up everything correctly.
Rockford also gets mad customers calling and emailing over non authorized companies not providing warranty and since it was purchased from a non authorized dealer neither will they. its just cutting out issues and trying to drive the authorized (companies with great customer service with real warranties) dealers sales up. most authorized dealers for Rockford list msrp price but sell for less, some even price match Sonic's and crutchfeild.

Not much longer to wait, I think at most with amps the might be adding the clip indicator light to the bdcp and the better selling multi channel power amps at most they will have something a little bigger then the t2500.1bdcp but i'm doubting that. I'm 90% positive that they will have some nice updated power series subs though. Hoping for an 18 similar to the old team rf or hx2 power series but with at least 1500-2000 rms.

This is the year Rockford should be updating there power series subs, it's been what 3 years since they last did? They better have some good stuff for us.

I don't know what to look for in Ann accurate scope. I know that it has to have a nice refresh.rate to see clipping at the.same time your taking readings from the other tools.
