Bass is almost always mixed to the center as low frequencies are
omnidirectional. If you only send the L or R channel, you'll lose
some of the signal strength (about 6dB if I remember correctly) and
the subwoofer won't have the "oomph" it should, but since you'll need
an amp after the DAC anyway you should be able to make that up easily.
That said, if you're listening to old Beatles stereo mixes, the bass will
only be on one channel (left, usually) and if you've sent the right to the
DAC, there's not much for the sub. I'd try and convert the signal to mono
for the sub feed.
