Default Sure 4x100 as 2.1 setup

I am wanting to run a sure 4x100 amp in a 2.1 configuration for computer speakers. Since the outputs can't be bridged I was just thinking that I could run a DVC sub off channel 3/4, would that work, or is there a better way? Also I will need to wire up a pot for volume control. Is there a wiring diagram that shows a master volume control and then also a fade control to control the sub relative to the main speakers? Thanks for your help!

DVC sub is a nice idea.
That should work.
or 2 subs, if you like.
Or, if you are short in space / wanna fancy things, an isobaric sub may be even a verry nice choice.

Suposedly You can wire up 2 pots.
1 as master volume, and the other to controll the sub.
Sub's pot takes input from the master pot output.

It seems like a workable idea to me. I would just use 2 regular pots for the L-R channel inputs (so I also had balance control) and a dual-gang pot for the sub inputs.
