Yamaha Studio monitors

First of all we have no idea of what you are asking. Your title could be any Yamaha speaker (wired or powered). The Guide to connecting 3rd party wired speakers to the Amp is in the link

They are powered studio monitors that have ¼ inch plug in back for the audio output. Not a traditional speaker wire set up. Like this

You would need a speaker to line level adapter.

With powered speakers I’d say  a Port would be better suited than an Amp.

Yes, I agree. My assumption was that the AMP is already on hand.

Thx yall ill get a port and get more speakers for the amp i have. 

Ok so i got the port and i can only get one speaker to play?? I switched the wires and the other one played. Does it only have one channel so it’ll only play one speaker i.e. only the left  

And yes i have the amp too

I don’t know how you switched the wires. Don’t switch too much at the same time or you can’t be sure exactly where the issue is. For example if you exchange connections at the speakers and the problem moves, you have learned that the issue is not with the speakers. Wires, PORT, and input to the PORT are still suspect. Systemically work through the connections and “boxes”. Also consider operator error. Never assume that the problem must be [ … ] or cannot be [ … ] or you’re likely to be blindsided.
