DJ50X SPEAKERS TO MIXER CONNECTION ISSUES

I am trying to connect both speakers to play simultaneously with my Reloop RMX80 mixer I use with my turntables, I don't know what cables to use to do this as each speaker obviously is a standalone active speaker. I'm new to this and haven't a clue about active speakers. This should probably be simple but I am completely stumped, can anyone please help, if any more info is required for your help please ask me, thanks, Ryan
