Re: Connecting left and right amps to one speaker

Is there a problem connecting both the left and right amps of a stereo
amp to one speaker?

Yes. The two amplifiers (left and right) will fight with each
other over who gets control of the speaker.

Both amps have the same signal going to it. Can I just connect the
wires which lead from the amps together and then connect that to a
wire going to the speaker?

NO.

Is there anything I must watch out for?

A good deal on a replacement amplifier?
(Or a good deal on repairing your broken amp)

I have mics and instruments going into a mixer. Their signals go
equally to the right and left amps of a stereo power amp. I.e. the
"pan" controls are all set to the middle position.

The power amp is a NIKKO 220 (120W + 120W) and the speaker is a Yamaha
SM15IV (Program [whatever that means] 500W, MAX 1000W). The amp takes
bare wire at the speaker output and the speaker takes a phono plug.

Use only one side of the amplifier if you have only one speaker.
Or use your amplifier in "bridged" mode (look it up in your
amplifier's user manual).

This is somewhat a generalization. There may be SOME
amplifiers that could take paralleling the outputs, but it
would not be reasonable to advise you from this distance
to try it.
