2 plugs, one output?

[TBONEU]

I have a Logitech Z560 4.1 computer speakers (http://www.amazon.com/exec/obidos/t...4617-9130412?v=glance&s=electronics&n=1197420)
The have two 1/8th plugs for the speakers to plug into the back of a sound card, like my Creative Labs Audigy on my PC system.

On my new PowerMac there is only one plug for sound output. If I plug one in on my Mac the sound is diminished substantially!

I don’t know if I Y-adapter would work.

I believe JBL Creature II speakers (http://www.amazon.com/exec/obidos/t...64617-9130412?v=glance&s=electronics&n=172282) only have one plug. On a PC I’m used to seeing two sound outputs, but Mac there is only one.

What should I do?

Do the speakers support an optical connection? If they do, you can use that assuming you have a Powermac G5. The other option is an external sound card.

No, optical connection is NOT supported by the speakers. Yes, I have a G5, Dual 2Ghz.
I rather not by an external sound card. I'm happy with the sound. Just need to fine better (newer) speakers.

What are some good 2.1 speakers?

The second connection is for the rear speakers. If you buy a y spliter it will just send the front sound to the rears. This is fine for music but not for like 3d efects in games.
