In the sub? You opened the speaker?

On a desktop you plug them into a jack located on your sound card (varies by card model) . Laptops use the headphone jack to connect external speakers.

You need some minimum amperage, bigger is better in this case if you don't know what it should be.

Based on the color-coded audio cables that came with the speaker system, connect one of the AUDIO OUTPUTS set on your audio source (TV, PC) to a corresponding AUDIO INPUT set on your speaker system.

The shielded wires are for ground, so they get connected together. Plug the wire into the PC and run some music. Then touch each wire to the others. You only have a couple of combinations to try...red-to-green and white-to-yellow, or red-to-yellow and white-to-green, . You can do this while the PC is one and music playing until you get sound thru the speakers. There virtually no current running thru the wires and you can't hurt the PC by doing this.
If the speakers use an external power supply, have it plugged in and working when trying these connection options.
