the higher the voltage, the higher the current, and the higher the power outputwhen using it, choose the volume close to the maximum, which may cause distortion and affect the sound qualityif the voltage is too low and the sound is amplified, it will easily cause sound distortionhow to choose the power supply?the power supply with the board is very key, the selected power supply ripple must be small, ripple large power supply will lead to power amplifier bottom noise, there is a current soundif the current is too low and the horn cannot be brought up, the voltage will be pulled down, which will lead to abnormal operation or poor sound qualityhow to select speakers?about the speaker type: commonly used speakers are generally 4-8 ohmsif you are above 19v 5a, no problem with 8-10 inches, power must be highly valued1chip: tpa3116d2(with am anti-interference function)power: dc12-24v/5aadapter speaker: 20-100w, 4-8ωoutput power: max0 (nessuna schermatura, 10 m)sensibilità di ingresso: 500 mvingresso audio: aux+bluetoothchannel: 2it is recommended to use 18v19v24v power supply with current above 5a100w(subwoofer)quantità : 1 pzil pacchetto include:1 x amplifier boarddomanda e risposta:1if you only have 9v12v or 1a 2a power supply, you can also use it but with low powerspecifica:item type: amplifier boardmodel: zk-tb21materiale: componenti elettronicicolore: blackversione bluetooth: 550w(r and l channel), maxif you only have 12v 1a, you can have 3-4 inch speakers
