No Sound Bose Speaker and Mixtrack Pro 3

Hi all,I recently bought a Numark Mixtrack Pro 3. My current set up is the mixtrack controller connected to my macbook pro via provided USB. A 3.5mm to 2 male RCA (red and white) cable, connecting the controller to my Bose Soundlink 3 speaker. And a pair of Bose headphones connected to the controller.When I play tracks in Serato DJ lite (free intro version), I get no sound via headphones or the speaker. I can provide more information upon request.
