As others have pointed out, trying to bridge the amplifier at its
output is risky. Fortuneately, you don't need to do that. Just use
one channel of the amplifier driving your single speaker. If you do
that, the only problem you have left is making sure that single
channel (mono) contains both the left and right from the TV. You can
easily bridge the low level signals that go into the amp. Now, what
does the output from the TV look like? If it is RCA connectors
(typically red and white), you can just use a "Y" cable as others have
suggested and your are done.


Ah, you are suggesting bridging the signal level inputs instead of the outputs.

That makes sense to me, but............isn't that what those circuits I linked do? Are you sure a Y-cable will work?
