I can't make sense of this.

One output of the DAC goes to the power amp (for the main speakers)
The other output goes to the sub.

So you won't have stereo. In that case, just send the mono signal
(L+R) to both channels of the DAC. If you don't do that, you'll
just be listening to one channel. And then I really wonder why
you bother about the bass - you'll be missing the entire second
channel anyway.

And why do you use *coax* cable between the DAC and the sub ?
A normal screened cable will do...

If you're a bit handy with a soldering iron, all it takes to
mix the DAC outputs to mono would be two resistors and some
short pieces of wire and connectors.
