They have their place... powering door speakers.//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

If I could afford or power them I would be running them.

i would put my vlx-400 up against anything in its class

Class D will be as clean in sound if run at a higher impedance such as 4 ohms and if you use a high quality class D amp. Some class D amps do not sound as good on subs as others. This is why I will never run any subs at a 1 ohm load.

I have heard there is a difference in dampening factor. Anyone wanna explain that?

 

[cleansoundzz 10+ year member]

The higher the ohm load on class D amps the lower the dampening factor. These days with technology being the way it is on amps, dampening factor doesn't make much of a difference. This applies to the higher quality class D amps.

Thanks man.

It's actually the opposite IIRC. Higher ohm load = higher DF, and DF get cuts in half with the halving of the ohm load. Basically high DF = good and low DF = bad, but when it actually makes a difference is anyone's guess and generally left to personal opinions and preferences.

Just wondering, since you said that DF doesn't matter yet you won't run a sub amp at 1ohm, what is the reason why you won't run it at the lower ohm loads? I ask because most people blame the low DF for bad transient response.

ha its cool thats all I run though. and all at 4 ohms. I don't really like it any other way. I have a 2800 watt Visonik v800hc getting upgraded right now for SQ and reliability. and my mids and highs will be through a new crescendo 1000c4 and ppi sedona and pc amps.

its the only a/b amp I know that draws 450 amps so idk much in its class.

i have about 2000 watts of class a/b power at 4ohms in my car:hide:
