Very good for my table radio that doesn't need a booming sound.

I used this internet radio amp with 5" speakers. Plenty of sound for music or voice. It's not a "boombox" but it's loud enough. The on/off volume is a big plus, as it can easily be plugged into a device like mine.

Pros
  • High-quality pure black gold circuit board, KEMET imported audio capacitor, filter capacitor with large capacitance per channel. Custom order black pure copper connectors, gold plated audio input connectors.
Cons
  • Protection

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.

Pros
  • Low quiescent current; noise reduction; Total Harmonic Distortion plus Noise: 90%.
Cons
  • Weak Set

Works perfectly. Best in Receivers and Amplifiers

I am using this amp in a portable ammo box system with PYLE 4" marine speakers (50W RMS?) , which are powered by 2 18650 batteries in parallel 3.7V Full volume and Pyles distortion, that's a groovy job 5 watts Update: 2x18650 in parallel gave long runtime but don't accidentally mix up one of the batteries that has the batteries and the amp burned up As I said, no more than 5 V. The LED still works.

Pros
  • Supply voltage: DC 5V (do not overvoltage, overvoltage will burn the chip); Input method: unbalanced; Output power: 5W 2ohm 5V / 3W 4ohm 5V / 1.8W 8ohm 5V
