Maybe anyone want assemble a mini amps for rooms audio? IC-Amp TDA2050 maybe this one can be a choice. besides the price is very affordable as well sound produced can spoil our ears. said the IC-Amp TDA2050 one is a rival LM1875 (though still better LM1875). This circuit scheme and pcb layout :

PCB LAYOUT TDA2050
Power amp output 30W,with VCC around 18vdc 2-3 Amper is enough for the speaker 4 "-6". although mini power amp but have good sounds.
