Sufficient output power is only possible if the input audio signal is strong enough and the power supply voltage/current are high enough!<br /> 2. The higher the power supply voltage, the greater the output power. The lower the speaker impedance, the greater the output power!<br /> 3. Please ensure that the power adapter's power exceeds the actual operating power of the amplifier!</span><br /> <br /> <p> <strong>Note:</strong><br /> Due to different monitor settings and lighting conditions, the actual color of the item may vary slightly from the pictures. Thanks for your understanding!<br /> Please allow a 1-2 cm difference in measurements due to manual measuring. </p> <br />&nbsp; </div> <div style="text-align:left;"> </div> </div> <div style="text-align:center;"> <br /> </div> </div> <div style="padding:15px;border:1px solid #AEAEAE;"> <div style="text-align:left;"> 1 x Power Amplifier Module Set&nbsp; </div> <div style="text-align:left;"> &nbsp; </div> </div> <div style="text-align:center;"> <br /> </div> <div style="text-align:left;"> <br /> </div> <div style="text-align:left;padding:15px;border:1px solid #AEAEAE;"> <span> </span> </div> <p style="text-align:left;"> <br /> </p> <p style="text-align:center;"> <br /> </p> <p style="text-align:left;"> <br /> </p> <p style="text-align:left;"> <br /> </p> <p style="text-align:left;"> <br /> </p> <p style="text-align:left;"> <br /> </p> <p style="text-align:left;"> <br /> </p> <p style="text-align:left;"> <br /> </p> <p style="text-align:left;"> <br /> </p></div></div>
