Design 2.1 Puissance Carte Amplificateur Multifonction Puissance Carte Amplificateur 5V20W Amplificateur Audio

The subwoofer must be matched well, and then installed into the box to make the phase inversion hole. Other parts shall be well sealed. Pay more attention to the haut-parleur impedance, mouth meridian and hauteur. If the impedance and mouth meridian are not consistent with its note stroke, it will not be enough. Not only the son is small, but also there is no shaking of the subwoofer
The same carte is compared with the following two speakers, both of which are 4 Euro: the son on the gauche is also 4 euro, which is not only very small, but also very poor son quality; The one on the droite performs very well in all aspects
This product can drive 5V / 20W (W), based on the principle of circuit, the secondary development and processing, the maximum power can be configured to 20W 10W bass + 10W sub box (5W x 2); so the power amplifier carte has strict requirements for power supply and horn,
