Traditionally, orange, green and black TRS cables are used in 5.1-channel audio applications. The orange cable carries the center and subwoofer channels, the green cable carries the front left and right channels and the black cable carries the rear left and right channels. Connecting your orange, green and black audio cables to the corresponding outputs of a 5.1-channel audio source will deliver the sound profile your speakers were intended to produce. However, if your source only has one audio output, you'll need to combine the three cables in order to get sound out of all the speakers.
