White Noise coming from studio monitors, wrong cables?

I just set up two studio monitors using a sound interface with a 2x RCAA Male to Male cable, and I'm getting white noise out of the speakers, sounds like this. Sound works and sounds good when loud, just when it has nothing playing or is low, you can really hear crackling and white noise. I will attach some photos of the setup, hopefully some one can point me in the right direction.

I tried fiddling with some of the buttons on the front of the interface but nothing changed, hopefully this is just an instance of having a wrong cable, and some one can show me the right one

Without any reference to the level of normal audio being played, it is impossible to tell whether what you are hearing is normal or not.
No audio system is dead quiet. All audio systems have some amount of noise-floor.
If you turn the level way up, all audio systems will sound like that.
The difference is how loud is that noise compared to normal audio playback.

Do your speakers make that noise when you do NOT have the RCA inputs connected?
Do you hear the same noise when the audio interface is NOT connected to the computer?
You must go through the audio chain link by link to see where the noise is coming from.
And noise by itself means nothing without reference to the normal audio levels.

The cables and connections look OK from your photos.
Of course, it wouldn't hurt to substitute some other RCA cables if have them (or borrow them).
Are the cables reasonably new and in good shape? Not dirty or corroded connectors, etc?

The sound in your video is just random computer "digital hash". Very common in computer audio.
It is not "white noise" in the traditional definition.

If I recall correctly, there were some threads around two years ago about noise issues with KRK speakers. You might search “KRK” and read a bit.

Right. That is why I asked about the noise floor of the speakers isolated from the input audio cables. And about the noise level RELATIVE TO the normal audio signal level.
