Review on π Acxico 1Pcs PAM8406 Digital Class D Amplifier Board: 5W+5W Dual Channel Stereo Audio Module for DIY Speaker Sound System by April Schol
Works perfectly. on receivers and amplifiers
I am using this amp in a portable ammo box system with PYLE 4 inch marine speakers (50W RMS?) powered by 2) 18650 batteries in parallel; 3.7 V. Full volume and piles distortion, that's nonsense. 5 watt update: 2x18650 in parallel gave long run time but don't accidentally mix up one of the batteries, it burned the batteries and amp. As I said, no more than 5 V. The LED still works. When used correctly, it is a great booster.
- Low quiescent current; noise reduction; Total Harmonic Distortion plus Noise: 90%.
- Weak Set
