Issues with my DJMONITOR 32 not playing any sound

Hi everyone, I bought the DJMONITOR 32 speakers days ago, i connected them to my external soundcard (AUDIENT iD14) but they don't seem to play any sound. I'm wondering if I connected something in the wrong way or if I didn't connect at all something that should have been plugged in. I'm really lost here, I'd appreciate any help! Thanks 🙂
