Could I use SSM3302 mono mode to output 20W in 4 ohm speaker at power support 12V ? Thank you.
4-ohm performance at 12V supply will look similar in both mono mode and stereo mode. The limiting factor is going to be the output voltage swing across the load. Stacking the outputs for mono mode only assists with delivering higher current to lower impedance loads. To get 20W at 12V you must use a lower impedance load.
