Is there anything wrong with the attached conceptual circuit?  Basically, I
want to mix two different audio signal and have them come out one speaker.
I know I could do an op-amp mixer + power amp but I'd like to know if there
is anything fundamentally wrong with mixing the two signals in the stereo
power amp circuit using a BTL arrangement where one speaker lead is tied to
one amp output and the other speaker lead is tied to the other amp's output=
..
Thanks,
