Hi,
This one is easy, if I understand your question.
Your L/R speaker connection consists of two (twisted copper) polarized wires, one for the + and -. These two wires come stuck together.
1. You need to take an end of the speaker wire pair and split the two polarities apart so that each + and - sides of the wires are separate enough that they can reach/fit into the back of your components. Simply take a pocket knife and slice down the center between the wires. Make sure you don't cut through the shielding.
2. Take one of the ends and use the wire stripper that Apaerion sent you to take off a little of the shielding from the ends of each wire so the twisted copper is bare. You may twise the bare wires with your finger so that they are tightly woven.
3. The banana clops consist of two parts, the pointy end and a bottom end that screws in/out if you twist it. Sometimes, the bottom gets loose in shipment so it is already screwed off of the banana clip. Just insert one end of your bare wire into the hole in the side (perpendicular to the pointy banana tip) and then screw the bottom on so that it pinches the bare wire.
4. Do this for all ends of your wire. You will end up with 4 + and - ends of your wires. Make sure that the polarities correspond on either end of the wires.
5. Simply insert the banana clip into the corresponding polarized connector in the back of your component (there are holes in the plastic round ends of the connectors that are colored black and red). Apply a little pressure and it will pop securely right in.
I hope this makes it a little clearer. I think a single photo of how it should look like would actually explain how it should be done much better.
BR,
Sany.
