is there any significance to a company displaying this logo on their product? do they have to meet some requirements like with a CEA logo? or is it just to fill space?
Not at all. CEA ratings are far to vague on how to "test". This means the ratings are no more clear/accurate then before.does having a cea certification always mean an amp will do what its rated?
Yeah there is a siginificance...it means the company paid IASCA to use it. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifis there any significance to a company displaying this logo on their product? do they have to meet some requirements like with a CEA logo? or is it just to fill space?
Best way to put it. A few used USACi and DB Drag for a while as well....most companies no longer worry about it.Yeah there is a siginificance...it means the company paid IASCA to use it. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
not really any specific company, or website... but there are those enthusiasts out there who do "real world" tests on a whole variety of amps... a proper clamp test is what you really should look for... and what i mean by that, is one that takes box rise, voltage drop, frequency, and electrical backing into consideration... basiclly comparing seperate amps, with as many of the variables taken out of the mix as possiblenoted is there any type of independent website that just tests and rates car audio using a standard test for every piece of equipment?
i'm not talking about bench testing, tho... and not because its not the better way to clamp it, cuz it is... but more just because the majority of clamp tests you'll see out there, are guys who are clamping amps in their cars, on their daily systems... and not a dummy load.Rating an amplifier at 14.4 isn't really a problem, if they were all rated at 14.4. Box rise should not need to be considered, since the amp can be tested without needing to use a speaker in a box. Voltage drop shouldnt need to be considered either, since the test setup should not experience it.
My comments were about the CEA rating, which is not conducted by consumers, on their work bench or in their car. Any standardized rating system should be conducted by the manufacturers (under strict guidelines), or an independent third-party testing organization. Such tests would be using a power supply sufficient to handle the amplifier being tested without voltage drop (otherwise whats the point), and would use either a static load, or a free-air woofer with standardized test recordings (probably just a tone at a certain freq).i'm not talking about bench testing, tho... and not because its not the better way to clamp it, cuz it is... but more just because the majority of clamp tests you'll see out there, are guys who are clamping amps in their cars, on their daily systems... and not a dummy load.
point being, if the OP is going to do research on different amps, and use other people's clamp results for comparitive reasons, then he needs to ensure that the variables of said tests are as controlled as possible... i.e. one amp getting tested in a car with rise and voltage drop taking affect, and another amp being bench tested with a dummy load.
if you can find one guy who is doing proper bench clamps on many different amps, that would be for the best... but, i have yet to find anyone doing that as of right now... which is why i say to make sure all the variables are controlled when comparing amps, or just to realize that they do have an effect on the results
