depends what connections your controller has whether unbalanced RCA or balanced XLR or it might have both.
IF it’s RCA you just need 2 RCA to XLR cables, on the sub there will be left and right balanced XLR inputs which your controller connects to…then there will be left and right XLR outputs on sub which connect to your speakers. I’m surmising that you have active speakers and sub
So it goes like this…..2 cables from controller going into sub then 2 cables going from sub to your speakers.
IF you are using AMP and passive speakers then controller left and right outputs connect to amp inputs then from amp to sub then sub to speakers only usually passive subs and speakers use TR or TRS connections.
As i’ve only used Active systems maybe someone with experience in passive systems can help you more if you are trying to connect your controller to a passive system.
