The power amplifier adopts MA12070 ch, the actual output power can reach 50W per channel, 2 channels total 100W (24V power supply), equped with 12V5A power supply. The output power is 30W*2 (4 ohms), if connected to 8 ohms. The output is about 15W*2. If you need more power, you can configure the power supply yourself. Be careful not to exceed 24V. Otherwise, the ch will be burned out and the power supply should not be too small, because power = voltage * current, if the current power is le than 50W. There may be a power outage.
