Hi, I'm new and this may not be in the correct location, but here goes (mods please move it if I am wrong!)

My Goodmans tower speakers currently have jack style connections to the main unit, however the unit is damaged and I wish to purchase a new stereo and use the speakers for my home computer.

The speakers have a universal jack the same as the ones on earphones, however I need a cable with two inputs for them, and one to go into the back of the computer.

Does such a thing exist?

Many thanks in advance
