I wired up the board and connected it to a pair of 10" 3 way, 4 ohms. I started with a 21 volt battery; at half gain (volume) limit. PS; same cut. After repeated Test with 19V and 12V power supplies; excerpt! I didn't give up, I just converted a pair of 6 1/2" 2-way, 8 ohms. I made the same test suite; all power supplies. No clipping at full gain and full volume on the MP3 player - NO - 1 clip at 24v with full gain/volume and the speakers still crack I estimate about 20-25w channels RMS X2 same output with Bluetooth or AUX IN I still need to add volume +/-, FW/RV switch or do a test with a micro SD card is not necessary I can do it with a mp3 player for the price it is very cheap only 8 ohm Plan speakers Would be 5 stars if it worked with 4 ohm 3 strips.
