its BNIB but it dosent have a warrenty.the girl i bought it from got it in a trade from a guy that got it as a replacement amp for the one that he originaly fried. He never used it tho. i wont be running it under 1 ohm anyways
The actual measured THD @ 1470W is right at 3% which in inaudible but I like to keep a few marbles in my pocket so I list it at 5%. THD @ 5% is a "soft" clipp level and is about the bare minimun most bassheads run their systems at. Many other companies use as high as 10% THD level when giving Dynamic power levels to make their numbers more impressive but don't specify the THD level.
I could have also listed a Dynamic power rating at 15.9V if I wanted to make the numbers even more impressive.
You don't find many competitors limiting their amps to 5% THD in the lanes.

Before I read your post I was just about to post something similar about the THD being inaudible at those levels but the sub performs a bit different either way.
something that is pretty high power because most speakers out today seem to love power.
i dont know if its possible but something like the jl 450/4 where it is 150x2 and 75x2 in the same amp would be awesome. great for people running active and great for people who want a strong front stage and mild rear fill.
or some small footprint 150x2 and 75x2
in my opinion those to power ratings are pretty optimum for speakers. most components take up to 150 fine and most coaxils will do great with 75. plus its pretty hard to find a quality amp that does 150 for a reasonable price. but as far as i know jl is the only company that does the 150x2 75x2 in the same case deal. which could be a big selling point since many people dont want to shell out the big money for JL
5% THD playing music in a car environment is NOT audible. Given the fact that most speakers produce nearly that much (or more) themselves makes that spec not critical in car audio. And most companies lie about their THD specs anyway, and/or don't specify when the level they specify occurs. IMD is a far better gauge of an amplifiers quality but very few manufactures dare publish those numbers.
the thd ratings you see on the most common amplifiers are rated at at 4-8 ohms...
if you see 1% or less of thd ratings it means that it will give you that thd rating at 4-8 ohms at a especial frequency... not for every frequency... as the ohmm load decrease the thd increase dramatically...
so if you see your amp with a thd rating of 1% of less and your bragging about how of a sound quality is your amp and your pushing it at 1-2 ohms of the 1% your probably getting around 3-5% plus the added THD(total harmonic distortion) of the cabin it will probably end up at around 8% maybe even a lil more...
in other words THD(total harmonic distortion) means that how much of a change a signal gets when it sends out of the amp than when it got back in...
so no matter what system you have THD will always be there...
WHY????
simply because each time a signal is passed to device(for example amp) additional DISTORTION or another words ANOTHER CHANGE is added to the content of the harmonics (signals).
dj those amps looks very good and with super good quality i wish i could get some but i already got some amps jeje... anyway if in the future i decide to change amps and audioque already have their 2000rms+ amp im sure i will picking one up
Damn, people can say what they want about your English, dude, but you've obviously spent some time reading up. I never thought about distortion from the cabin. Thanks for the knowledge. Props, man.
heres an internal pic. if anyone wants it in a larger size to zoom in more pm me and ill send it because this forum doesnt let you post bigger pictures then this.
DJ, are you guys changing the name to Audio Q or keeping Audioque? i just noticed the banner on the site says Audio Q but almost everwhere else it says Audioque. Im just curious.
The business name remains the same and will not change. We changed the "branding and box logo" to AudioQ at the request of our Spanish Speaking friends who had trouble with Oue.

Alright, so if I'm bragging because my amp puts out godly power at 1percent THD and then I get THD from the cabin and end up at 8 percent so what?
Now let's take an amp that's already distorting and doing godly power at 5 percent THD and add your THD from your cabin and now you're at 10percent+ THD. Think about what you said bro, it was kind of stupid. Amps rated at low THD are better sounding at amps doing the same power with a higher THD. Makes sense doesn't it?
