Hi guys, This is a design of the amplifier I am trying to implement, I need help bridging the output of the amplifier to get a little bit more power out. Also maybe put op amp in the input as a buffer circuit. I am not sure how to go about doing that, any help is greatly appreciated.
Thank you

feed the same signal into both inputs - use two speakers, one on each channel.

or for mono applications, TPA3122D2 may be used as a Bridge Tied Load (BTL) amplifier.
The traditional class-D modulation scheme,
which is used in the TPA3122D2 BTL configuration,
has a differential output where each output is 180 degrees out of phase and
changes from ground to the supply voltage, VCC.

see Figure 29 on page 15 for BTL Schematic ...

Can you explain it more I don't exactly get it
