Just in case you didn't know or people are wondering what you are talking about: these speakers are designed to give stereo output from 1 speaker, hence the two tweeters.
Now you could for example hook one up for left and hook the other up for right using the appropriate terminals.But if you plan and linking them together, for example, running speaker wire from the right terminals to another speakers right terminals, you need to research running speakers in parallel. You would need an amp/integrated amp or receiver that can handle that.
Since you have only one set of wires per side like described above, you run one the left on the left speaker and one for the right speaker using the appropriate terminals.
Be seeing you, the Prisoner...
