When you say "wired across the two positive speaker terminals on my
stereo power amp" do you mean something like:

[left channel power amp+] to [3rd speaker +] and [right channel power
amp+] to [3rd speaker -]?

or do you mean:

[left channel power amp+] and [right channel power amp+]  and [left
channel power amp-] and [right channel power amp+] to [3rd speaker -]

?

The second seems more likely to work, but since the wave forms would be
added together (?) I would guess that you wouldn't get the difference...

unless the first scheme knocks the signals out of phase...

Is this part of the whole surround sound thing?
