I need to do some creative experimenting if I can use my set of Samsung Speakers on PC ( not sure if working ). It has 2 inputs which are marked RED and BLACK like it used to be in my old DVD player speakers. Only possible connection is to connect Electrical wires.
How Can I use this with my PC. what are these speaker types called ? Spring Speaker terminals ?

Those are RCA connectors, what you need is a RCA to 3.5 mm converter, or make one yourself if you have the soldering skills

I have experience with soldering . So let me see from where i can find this RCA to 3.5mm Converter ? how much will it cost ?
