Wuzhi ZK-MT21 Bluetooth 5.0 Subwoofer Amplifier Board 50WX2+100W 2.1 Channel Power Audio Stereo Amplifier Tone Board Bass AMP AUX

Today, I've resurrected my 23 years old branded Hi-fi speakers to life with this compact & impressive amplifier. This amplifier can make any brand system to run for their name. Unbelievable loudness & bass quality. Make sure that your speakers are capable of handling the power of this amp. My speakers were 23+ years old. The power supply was 15+ years old PC adapter, 19.5v 6A. The result was a satisfaction that I've been longing for almost a decade. I think with more Voltage this can crank up even more. Thanks to InkOcean & Amazon.

this is a good piece of electronics if you like quality loud sound .. go ahead you can invest in this.

Usually, I don't post reviews but doing it for this item because has a bad experience after receiving the product. I have returned the product immediately when I noticed the issue. First of all, I would like to start with the cons as it has many. 1. The unit I received was not working properly or this is how it is designed as when I plugged in with a 3.5 mm jack connection the sound output received is a mono channel or you can say both the channels are overlapping, I have tested thoroughly with multiple cables and sources but the issue stays. 2. The second option is to play through Bluetooth but there are a few issues here as well, when the Bluetooth is connected it is prioritized over the aux connection so you need to disconnect the Bluetooth to play through aux, the Bluetooth connection is not secure and anybody can connect when it is on, there is no option to change the source or switch off the Bluetooth. There is a delay of 1-2 seconds when the audio is played through Bluetooth so you have a compromised experience while watching videos or playing games, it is only good for playing mp3 music. 3. The third point is the cost you don't get what you pay for the case is made of plastic at this cost they could have offered an aluminum box enclosure or frame, the frame can easily break. The Pros are as follows: 1. The sound quality is good, I connected a basstube (12") and two 4" speakers, the sound output is decent and the audio tuning option work well. 2. Very compact size compared to the power output it delivers. Overall it is an unfinished product and I cannot recommend this to anyone. Hope this review helps.

Wonderful product! The team who designed this amplifier should receive much credit. Delivers more than expected. Drives 10 and 12 inch subwoofer like a beast !!!!!!!!!

Its a well engineered product, I'll give you that. Bluetooth also works without any noise. And without any Chinese girl dialogues. Trust me, though it burned my pocket a lil bit, it's a 2000 rupee worth product. 2000 we can say because of the effort they've put in. Bought with my pocket money for my birthday, you know, giving yourselves a favour 😄.

Sound quality.. And built quality awesome really I love this amplifier

Very crisp and clear sound. I am useing 24v 10a power supply and it delivers very loud sound... I was not expecting that from a tiny amp... Very nice and good quality
