How to connect Your iPod to big speakers?

What will I need to connect speakers to my iPod?

• These are pretty old speakers which I found in a cupboard. They look pretty decent though. They're Aiwa 3 way twin duct bass reflex system. On the back there is a Black switch with a negative sign above it (-) and a red one with a plus sign above it (+). I have managed to hunt some wires out as well. Any help would be greatly appreciated.

• Answer:

  I think that black and red connector for voltage. If you have an old ipod headphone cut it at the end of speaker. Then take out little bit of wire from the plastic shield of wire. There have 2 wires inside on speaker point.they have a colour cotting. Remove colours from the wire with a knife/ blade.connect that 2 end to your speaker input. Don't connect to speaker directly...
