Only the headphone output is powered. Moving from there toward the optical end of the card are your Front L/R line out, Rear L/R line out, and center/sub line out. All are passive.

Assuming you have the typical 2.1 package with a powered subwoofer that also feeds the L/R main channels, you run a 3.5 mm cable from the Front L/R main on the Z to the sub, and the L/R fronts feed from the sub. (sub and rear ports not used)

If you have separate, non-matched sub and main speakers, it's runs just like the label. Your L/R mains will run on a 3.5mm line out from the front L/R port and the sub will run on a line out from the sub port. (rear port not used)

If your sub isn't powered, your going to need an in-line amplifier or another plan.

 

So decided to go with a couple bookshelf speakers. The question now is if I order an amp what socket do I use for that? Also I'm considering 2 books shelf speakers and if I decide to ad a sub later what would a good amp be to do that?

Speaker amplifier, right?

Spoiler: Warning: Spoiler!

You just use the front speaker port of your SBZ.
