Low volume on speakers

Hello,

I've just started my journey into LP's, so I bought the AKAI Turntable with speakers.
The description says the speakers "come with built-in amplifiers" (it also says that it comes with bluetooth but it doesn't), so I wanted to try to connect them to my laptop through my Audio interface (steinberg UR22 MKII) but the volume is very low, if I connect them directly to my laptop then the volume is a little bit higher but still low (connected to the turntable they sound great)

Now they don't have plug, so I think it is a power problem.. I'm not experienced with speakers, maybe I need an external amplifier ?

Thank you for your replies
