    Can’t believe this tiny amplifier can drive 8 inch woofer ?approx 40 watts


  9. arpan0823 (verified owner)

    Note that the output power is 3w with 4ohm speaker impedance. With an 8ohm speaker the output will drop to ~2w (as per the datasheet and observation)
    Anyway extremely satisfied, thanks to the excellent shopping experience and super fast delivery by

  17. choralsilence (verified owner)

    this module sounds very clean, and can deliver the full rated wattage of power, but take care if your power supply can supply the minimum required current for your setup, in which case this is unbeatable!!

    The best audio amplifier. Listening to it’s sounds you will forget the meaning of noise. But, it requires a good quality regulated power supply.
