Hi, I've built a really basic set of speakers in my speaker building class couple years ago and I decided to hook it up to my laptop after finding it in a closet. Now, the back of the speaker looks like the picture. Not sure which cords would connect from that to usb or some kind of a way to play music from a laptop.
It's much too embarrassing to know that I've built this..

So if anyone can kindly show what kind or a link of cords where I can get'em, it would be very much appreciated.

Thanks!
