How to hook up JBL Control 25 speakers? - how to hook up grex to the back of cinevision rv4000

So I took 3 JBL Control 25 speakers and really have no idea how to connect something in touch. I have very little experience with speakers and sound systems. What was I to these speakers? And any help with the installation would be great! Thanks in advance!
