2.0 - 2.1 question

[Ionic]

So I have

and
http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=109-040&scqty=1

Sitting in my shopping cart. I'm wondering what else I would need to add a sub into this down the line?

 

[450]

A subwoofer that takes speaker level inputs or stereo rca inputs.

Something like the Dayton SUB-80 would work.

 

[Ionic]

So just the sub, no extra cable? (aka, cable different then the speaker cable I'm already getting)

 

[450]

You might need more speaker cable, but thats it.

 

[Ionic]

Well... For that price I may as well get the sub now, and get a little more cable. Thanks! This should hopefully be a step up from my Dell speakers.
