Feature

●HIFI CHIP:XY-502B Adopt TPA3116D2(with AM Interference Suppression Function) Chips, With Excellent Sound Quality. It Ensures That Even With High Power Operation For A Long Time, THD Is Less Than 0.1%.
●WIDE INPUT VOLTAGE: DC 9V-24V, Can Be Powered by 9V/12V/15V/18V/24V
●TWO AUDIO INPUT WAYS:User Can Directly Connect with Wireless BT 5.0, or Choose the Headphone (Line in) Way
●PROTECTIVE FUNCTION:This BT Amp Is Designed with Protective Case, Over-voltage Protection, Under-voltage Protection, Over-heat Protection, Short-circuit Protection
●TIP: adequate output power is required when the audio input is sufficient and the power supply voltage/current is sufficient, the relative power will be higher. Different impedance horns will have different output power.In the case of sufficient voltage and current, the larger the impedance horn, the smaller the relative sound power, please pay attention!

Let our old speakers get cooler

We have a lot of speakers with very good sound in our homes, and we rarely use them because there are no Bluetooth receiver modules. Now lets convert the ordinary speakers into cool and stylish Bluetooth speakers. More importantly, this is your own modified speaker, it is also unique. This embodies your cleverness and great hands-on ability, which has different meanings.

Finally, remember to share your achievements and happiness with you!
