2. If connect to DC 12V-24V, the Current needs more than 3A.

Warning: Pls select only one connection method !!!


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.

=> If the output impedance of the amplifier requires 4-8Ω, the impedance of your speaker should also be 4~8Ω, the sound of 4 ohms is louder, and the 8 ohms is smaller;
=> If the output power of amplifier is 35W, the speaker should be around 20W. For 1.0 channel, the power is 20-30W, for 2.0 channel, it is 2x(20-30)W.
=> If the amplifier is full frequency, the wider the frequency response of the speaker, the better, such as 100~18KHz.

● The speakers must be based on impedance and power, regardless of dimensions.
● 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.
● Pls make sure that the required power supply is used and working properly.
