Hi all,I am a newbie and I need some suggestion or explenation from my problem,I have a Korean 1200 watt class D monoblocks amps which have a noise come out from the subwoofers and the noise is like a 300 hz till 500 hz test tone (some where between that) and 10 of the amps which I tries have the same problems but different tone and loudness.
I also have some similiar problem like that with Orion 2500D last times (around 2004) but the last produtcs already fine (no noise again).
One of my friends said that all class D amps will have the same cases like that which have noise but every brand have different tone and loudness.Is that true???
But I don't get any problem like that in some brands.What I need help for is there any solution for this problem or is there any way to up grade or change some or any of the component so the noise will diseppears.because I have around 50 pcs of this amps and I don't know how to solve it.
Thanks

1200W in a car..how deaf do you want to be?
I have 2000w/rms in my car and its just loud enough for my taste. Even though it feels very powerfull, its not the same as having 2000 watts on an indoor system, it seems lacking somehow.
It seems lacking?
Normally in a car like that you don't even want to be sitting in it.
Is that the actual power or just what's stamped on the amps?

LACKING.........gee....don't you get deaf??? Ofcourse it lacks something in comparison with your living room/study.
Not lacking in power but something else, like openness. Its kinda hard to put into words.
Thats actual power, the rating stamped on the amp is 4000w/rms😱 . Its a Visonik V4000XD rated at 4000w/rms @17v. Thats if you can supply that kind of power. I have a 16v alternator and batteries, but with voltage drop at full power I only get around 2000w/rms.
BTW, thats a class D amp, just to stay on topic 😉 .

Maybe the source?
Yes in car audio you would use digital delays to overcome the size of the surroundings and enchance stereo imaging and soundtage.
You'd also try to tune the bass to the natural resonant frequency of the car for max slam.
