Sundown testing... the build up.

It's not about marketing at all and your accusations of such are a perfect example of why you could not be trusted to "test" this product, nor any product, in my opinion.

lol this is where u are wrong. This IS marketing, this is far from science. This product has already been sold and is in wide use, this IS marketing. Keeping the brand/model talked about - marketing.
Look, I dont use it and I am talking about it - that is the whole point - good marketing. Do you have this amp? No. Are you arguing with me over this? Yes - good marketing.
This is all about BRAND AWARANESS, keeping your name at the forefront of consumer's mind, watch when the 3000 comes out no one will care or even remember all these tests with the 1500 amp. Tell me about science then. All this is, is good marketing.
you made me laugh with "your accusations" comment. Dude im sorry to say it but you dont know anything. It really does not matter how good or how bad a result it, as long as you have both results contradicting each other - it only helps the publicity.

Jordy, do a few diff tests.. first do a street setup test with 1 battery, then the next do it with a bunch of batteries..
make sure you record all the numbers (voltage and amps out of the amp, voltage drop from the battery, and if you can the current draw)

you should take it up on a roof of the tallest building in Ottawa and toss it down, see if it glows while air born.
what i personally think is the dude that makes/sells these amps has totally killed the product's credibility. After reading many of his replies I, to be honest, do not really care to see any test of this amp anymore. But that's just what i think.
Let's think, what is the point of YET another test of this amp? Is someone that insecure in their product? It's only a 1500 watt amp, who really cares if it makes that or not? All the kids around the block seem to love this amp, let's just leave it at that.

I don't remember if it was someone from sundown or ultimate that I offered to test for, got an initial response... then nothing...
Anyway Jordy... IMO the only test that is going to mean spit will have to use a non inductive load... testing output with subs will give a reactive number that will vary from sub to sub and will always measure high......... Id also suggest you setup a laptop with a voltage divider and a copy of RightMark audio analyzer (free!) so you can report THD #'s....
As far as the meters... just let us know what you are using so everyone has an idea of accuracy... a cheap clamp might give about 3% + 8 digit count accuracy, which could work out to it being more then 20% off....

I agree with what Chris and dogstar both said. The big thing will be to measure everything for each setup, including imp rise etc.
I think you should test one amp off a completely stock electrical at 1 ohm nominal like Jacob said these amps were made for.
To quiet down us rowdy westerners, I think it would be a good idea to do some battery limited dbdrag street tests (off 1 and 2 good batteries) in a pure burp setup (car off) and lower impedances. Most serious competitors run strapped pairs (2/4 amps per battery), but I guess that depends on how many amps Jacob sends you.
Testing a street beat setup at sane impedances and with a realistic # of batteries behind the amps to minimize voltage drop would be good as well.
The only amp I'd be curious to see on 16+V is the 3000d (again burp setup with a big battery bank).
Just my $0.02.

The best way (imho) to measure how an amp will do in a vehicle with a sub is to actually test that way.
Also, we're discussing straight power here. THD hasn't even come in to the equation yet and I'm not confident that I would be able to test for it properly.
