Some background. So I have what seems like a Vizio soundbar that stopped working one day. Further inspection reveals the pcb board and speakers look okay. I still could not figure why it no longer works. I decided to keep the soundbar since the speakers are still good and replace the pcb board with something else. There are four speakers. Each speak is 4 Ohms, 10 Watts. Two speaker are linked in series which gives me 8 Ohms and 20 Watts if my calculations are correct. Question is how to power them?
You can buy amplifier modules off of ebay.
You would need to check the current supply to see what volts it is for your new amplifier modules.
