I have a couple of speakers and a kick ars sub and I want to hook em up to my computer, the problem is that I have no idea on how to do it.
You'd probably have to buy some sort of adapter to connect all the speakers to your computer. At least in this one I did. You'd need to connect all of them together and then connect them to the computer.
It's done in a similar way to your regular speakers: Connect both of them and then send one cable to the computer. This has to be done because the computer doesn't have enough ports in which to conect each speaker separately.
Buy a cheap, separate reciever and hook the speakers up to the reciever and the reciever to the computer. You can do the same with the subs or use an amp and plug the RCA jacks into the reciever.
