Greetings,
I have a pair of active bookshelf speakers (with AUX cables coming out of them). The speakers are connected through a "center unit" with radio, cd player, line in etc. I would like to connect the speakers directly to my PC, but when I do so the output volume is low. What do I need to connect them directly (without the "center unit") to my PC and get louder audio?

the system model is CD 1260 by Graetz, can't find anything about it. There are only 3.5mm cables coming out of the speakers, nothing else.
