Wd515 - You will need interconnects from your source (iPod, CD Player, etc.) to the SP3. If iPod, it should be phone jack on one end (can be inserted into the headphone out of the iPod or the out of the dock) and RCA on the other (a red and a black usually). The RCAs go into one of the inputs of the SP3 (any one should work unless marked 'phono').
The plastic turny things are for your speaker cables, from SP3 to speakers. To get things up and running just go to Walmart or whatever and get some interconnects and speaker cable and hook up, making sure red is connected to red and black to black. Then you can start to look at other options as far as upgrades go.
