Sundown testing... the build up.

I think that is closer to reality than most of the applications that have been listed for this amp.
Lets face it, sundownz has admitted it's not an spl monster, and that it's not optimized for "street" class competition. Kind of a red headed step child, do you beat it or praise it?
So, IMO the question of you Jordy, is prove what this amp is good for.
Does it do rated power at rated load in a normal every day car, or is it a piece of crap?

Now... what is so unbelievable about that I have no idea.
What I've said it's not good for... is burping at ridiculously low impedance on one battery. This isn't a real situation... this is an artificial situation created for dB drag competition. The amp works great @ 1 ohm in a typical vehicle, but will not perform optimally @ 1/2 or 1/4 ohm in a typical vehicle OR a Street SPL class. I don't know why this has been so hard to understand for some people.
What I want Jordy to do is to test it primarily @ an actual one ohm load. I can achieve an actual load almost exact @ 1 ohm on my test bench... 0.6 DCR load on a pair of SI Mags in my test box at 55 Hz gives me 1.08 ohms (a little higher when testing more power and things heat up). I can get within a few percentage amp to amp and repeat my tests.
I told him to "go for it" on lower loads, but they don't excel there when current supply is limited. As I've said over in the other thread they lose alot of efficiency when ran down that low as they are made to be 1 ohm daily driving amps... I never set out to market them to SPL guys, they came to me and asked for them.
Anyhow... this thread is already getting out of hand like the other one. Has anyone ever stopped to think why this only happens on CCA? Why, on every other board on the internet, do people that run and test my amps not have such a problem?

Yuli,
I don't consider this marketing... I would be more than happy if this ridiculous argument regarding my amps didn't seem to lurk around constantly on CCA. I do consider this a huge waste of my time since I *know* that the product puts out it's rated power -- and so do HUNDREDS of my customers. Why certain people can't believe that I have no idea.
My company is pretty small, I do most of the work... I have alot of other things that I could be doing than posting here. I'm here because the stuff that people are writing is hurting Steve's business, he's a dealer for me, so I want to be sure people know the facts about the product he is trying to sell.
I also have no idea why you have such a bad attitude about this. You KNOW that just because an amp doesn't excel at 1/2 and 1/4 ohm in your Street dB Drag car doesn't mean it won't produce it's rated power at 1 ohm. I've even told you that they won't do very well at extremely low loads with limited battery support. Why you and I are still arguing I have no idea. Seems that we both know that the 1500D doesn't excel in Street dB drag limited battery installs at super low loads.
The only disagreement we are having, I suppose, is that for some reason you won't admit that it's quite possible that the 1500Ds will do very well with more battery support. It's more than quite possible, people have tested it. Every test but one, the one recently performed in Canada, has shown excellent results with larger battery banks at lower impedance loads (loads under 1 ohm where extra batteries are required, just so we are clear).
Or maybe that you misread my comments and thought I meant that they need huge amounts of battery power for ANY load. Okay, sorry if you got that from my words, they work fine in stock vehicles @ 1 ohm. Is that clear? I'm sure you will have no issue agreeing with me once Jordy tests the amp... since it seems that you have your doubts about my USA testing.
Honestly... I'd rather NOT argue with you or anyone else here. I'd like to come over here to CCA and read and write useful posts and helping people out. I started my company since I LIKE car audio... not to argue with people about what my products will do when it is WELL established that they do what they say.

I would also like to know what kinds of meters were used when testing these in the U.S.? I`m not trying to start anything, but would like to know.

Like I said, I don't have Fluke meters though...

JL and Alpine amps are also overpriced, but they also have features making them somewhat worth the money (JL's variable impedance input = same wattage output).
Sundown amps are clean as hell, and very, very nice looking overall, but 1500w for $750 just isn't competitive.

Have fun testing jordy!

I just wonder how bad the post-testing "I told you so" barrage is going to be. Could be a rather interesting day.
