Default Sound card as source, two different monoblock amps.

Just brainstorming:

Most PC 5.1 sound cards use a single stereo 1/8" jack for center channel and subwoofer output.

I thought about a single-chip for the center channel, and either a parallel or bridge/parallel for the subwoofer, for more power.

They'll probably be on two different power supplies, for differing voltage requirements.

Would two different power supplies cause a problem with the common ground 1/8" jack?

Hi,
the two monoblocks are effectively separate.
Split your output into twin feeds and send them to the amps.

Does this require additional active components for isolation, or is it a matter of splicing the common wire and not worrying about it?

Hi,
if your monoblocks are separate then it matters not that they share a return connecton at the stereo outlet plug.

Yes, just take a feed from each stereo output pin and a return to the ring.
