HacbopZK-TB21 TPA3116D2 Bluetooth 5.0 Subwoofer Amplifier Board 50WX2+100W 2.1 Channel Power Audio Stereo Amplifier Board

At last, a cheap amp that does what I want, and does it well. I had to try two or thee 3.5mm stereo jacks before I found one that worked properly with it. But wow, for the money it's excellent. Quiet too, and wonderfully compact. This is the best cheap Chinese-made amp I've tried so far, and I've tried a few. Now it just remains to be seen if it keeps on working!

Love this product it's so powerful sounds good too. The only problem I have is that the Bluetooth stopped working after the first use but all in all aux works fine.

I am going to build a portable box but tests and pre built on 24v. Vocals are extremely clear.

The media could not be loaded.  The amplifier in the aftermarket unit in my daughters MX5 powers the front and rear speakers. I upgrade the door speakers but there was still a lack of base. I bought a small subwoofer which I fitted behind the seat. I initially connected it to the header unit sub out via an even cheaper power amp. The result was poor. There was still no base and volume was pitiful. I returned that unit and ordered this one. Okay, it’s £10 more but it’s still a bargain. I’m not using the left and right out only the sub out. The result is a credible base driver. The seats were so low to the ground that there wasn’t enough height to fit one of those aftermarket undersea bass subs, so this great little lamp enabled me to engineer a solution which is quite adequate. It probably wouldn’t power a massive bass sub in for so little outlay of significantly improve the sound. I’ve stuck it to the side of the glove compartment so it’s hidden away along with the Aux/iphone connection to the head unitI haven’t tested the Bluetooth function or the other speaker channels, but I’m sure they’re comparable. Hopefully they’ll be longevity .

The media could not be loaded.  Interesting bit of a kit. Figured after a few days that it does Bluetooth too.Got enough power to drive a 10” subwoofer. The audio quality could have been a bit better. There is some interference/noise you can hear when it’s set to high volume. For the price, it’s decent. Will update this review after a few months to see how it fares.

Exceptional value for money, works perfectly, don't know how they make them for the price. Top quality sound, identical to higher priced products on Amazon. To reiterate, Bluetooth definitely installed.

I used it for upgrading a 1970,s record player
