How to match the AMP and Speaker:
1. The impedance of the amplifier is the same as the speaker, can not be too far apart.
2. The power of the amplifier is 1.5 times than speaker to obtain a enough sense of strength.
¡Ü If the output impedance of the amplifier requires 4-8¥Ø, the impedance of your speaker should also be 4~8¥Ø, the sound of 4 ohms is louder, and the 8 ohms is smaller;
¡Ü If the output power of the amplifier is 35W, the speaker should be around 20W. For the 1.0 channel, the speaker power is 20-30W, for the 2.0 channel, it is 2x(20-30)W.
¡Ü If the amplifier is full frequency, the wider the frequency response of the speaker, the better, such as 100~18KHZ.
TIPS:
¡Ü The speakers must be based on impedance and power, regardless of dimensions.
¡Ü If the sound is intermittent or hoarse during increasing the volume, it means the speaker and amplifier are not matched, Pls use small sound or change a suitable speaker.
¡Ü Pls make sure that the required power supply is used and working properly.
