You can have the front and rear jack working at the same time. If you have a six-channel setup, you use three jacks.
Ryxpia, take a look at
Rubber Stamp's 5.1 channel song thread and see if it helps.
Also, if you're playing stereo stuff, it's usually only plays from the front two speakers. There's another thread here about getting getting ITunes to play over all speakers, I'll look for it but I can't remember it exactly or who made it.

I have called it a splitter. I use double adaptors for mains power though (and power boards as well).
