Usually the amp inverts the channels internally, automatically when you
bridge the outputs. Usually all you have to do is connect the Left+ and
Right- (or vise versa L- and R+) to the speaker. I have had amps in the
past that had a switch to toggle between bridge mono and stereo. IMHo
you should consult the manual just to be sure.
Those amps can not handle impedence loads below 4 ohms when bridged, so
whatever you do pay close attention to the speaker impedence and your
wiring. Dont want ot pump too much current through the mosfets.
