This power amplifier using or based on ic tda7377 that the tda7377 ic has 4 channel input and 4 channel output. For using 2 1 power amplifier on two channel is bridge to one output so the output is 3 channel one channel using for bass or subwoofer speaker. Properoperationre quires that p gnd and s gnd leads be con nected together on the pcb layout by means of reasonablylow resistance tracks.
Complete circuit power amplifier 2 1 3 channel with tda7377 include in the layout power supply bass filter as well as the full pcb layout.
The tda7377 amplifier is a class ab car radio amplifier able to work either in dual bridge or quad single ended configuration. For using 2 1 power amplifier on two channel is bridge to one output so the output is 3 channel one channel using for bass or subwoofer speaker. The tda7377 amplifier is a class ab car radio amplifier able to work either in dual bridge or quad single ended configuration. See circuit diagram below.
