n00b question:

whats 'impedence rise'?

n00b question:

It's the rise in resistance, caused by inductance, that you get from the "circuit" that is created when you put your sub in an enclosure.

ok....

and how do you 'lower' it?

You don't.

You build a new box //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

There are other factors to imp rise however.

I appreciate the differences when compared to other amps but I don't care for you throwing around numbers that are not accurate.

And what I'm saying is that the "power" ratings you are getting are not true. You are measuring Volt Amps and not watts. There IS a difference and that difference is pretty large due to the reactive load you're using.

And no, I wouldn't be surprised about impedance rise because I do understand it and I do know that it takes place.

Then tell me how to accurately determine actual wattage then.

The way we did it is the way that i've ALWAYS seen done, by anyone. It's the same way loyd tests amps, its the same way scottie j tests, its the same way EVERYONE tests. Except for you apparently.

I'm not sure what you are trying to accomplish with your posts. Seems like you are just being difficult for the sake of being difficult.

The ratings I produced are REAL world results that nearly anyone with a decent electrical system can acheive. If you somehow see a giant flaw in the way things are done, then do them yourself.

I thought I was doing a service to the caraudio.com community (at least as far as I can tell from all the people thanking me for posting the tests), but apparently you don't see any benefits from it. Maybe I should just stop testing amps all together until I learn the "proper" way from you? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

For the sake of this thread and its relevance to the topic, don't bother posting any more of your shit in my thread.

oh lol

duhhh

thanks.

i need a voltmeter now so i can tell if i drop too low.

Loyd has a Eagle Pitcher 12500 I believe. Its about 4' wide.

That really didn't make THAT much of a difference in his test vs. mine. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

He actually had MORE voltage drop than I did.

Alright, i know NOTHING about these amps

But why are they so HYPED up

1000 watts at 1 ohm? I dont know, that just doesnt seem like very much, unless they are insanly cheap to buy?

If you would read through all the results, the amp did 1090 watts rising up to 2.7 ohms, not 1 ohm

Give this amp an ACTUAL 1 ohm load (say, wired down to .5 ohm with an impedence rise up to 1 ohm), you will get AT LEAST 1500 watts out of it, which is exactly what it's rated for.

And even if it WAS a 1000 watt amp, the RETAIL price is only $600

Well Ill be sure to add my result to here if I can get a clamp meter that works right. Ill have two strapped on a .7 load.

Thats going to be amazing. Hopefully you get that meter working.

Yeah, I saw the rise part

Ive just seen this amp posted about heavily, and wondered what all the hype i was seeing about

Whats actually cost per amp? Strappable?

As far as I know, they are $600 direct from the company or any of their dealers.

And yes, they are strappable.

1500 x 1 watts @ 1 ohm

800 x 1 watts @ 2 ohms

400 x 1 watts @ 4 ohms

Here are the ratings by the way.

Dont the eagle pitchers rest at a lower voltage but can give out much more current?
