connect laptop to home theater system?

I have one of those home theater systems that are usually used with
PCs.
It has 5 small speakers which connect to the amplifier/woofer.
The woofer has three inputs (3.5 mm sockets) labeled FRONT, REAR and
CENTER/SUBWOOFER.
I was told that there are some special PC sound cards which have 3
outputs,
one for each input on the subwoofer. (I think they are Mono inputs)
The problem is that I want to connect the system to a laptop which
only
has one stereo output.

Can i create a special cable for this purpose? Is there a way to
safely
feed all 3 inputs of the woofer from the stereo output on the laptop?

Any schematics for simple circuits would help a lot!

thanks,
Andreas

 

usually these speaker sets will come with some sort of way to connect all
the speakers to the stereo jack, by plugging some of them together. i ran
into this problem at work with an older computer.

try running a search for the model name of your speakers, or go to the
company's web site, and get a manual. it should tell you how to connect
the speakers to stereo output.
