How to have multiple audio outputs?

How to hook up a stereo with different audio outputs?

• here's the thing: I have a stereo that only has RCA inputs and outputs (one of each) but I have another broken stereo whose speakers have a different audio output that I don't know what it's called (a thin red and black wire that connects to red and black square,correspondingly,that you pull up and insert it there) and my question is... What do I do to get those speakers (red and black wired) connected to my other stereo that only has RCA inputs?? Like what do I need to buy?? thanks for your answer!!

• Answer:

  Power Amplifiers and /or Receivers have a Push-and-insert connector for the speakers. The RCA connectors you mention on the other Amp you have may just be Low-level signal outputs to be connected to a power amp, but they wouldn't be for connecting them directly to speakers. First find out what is your Stereo, find the User's Manual and see if it has a power out section, or if it just a pre-amplifier. Post the Brand and Model Number.
