DollaTek HiFi Wireless Bluetooth 5.0 TPA3116 Digital Power Audio Amplifier Board TPA3116D2 50WX2 Stereo AMP Amplificador Home Theater

This is a compact amplifier that accepts a phono -plug or can be used with any Bluetooth device. Speakers are hard-wired tot he rear of the unit.The amplifier is delivered as a kit - that is, you have to screw together the base and top (every thing is provided for this, including a screw-driver).It was easy to set-up and connect to a device and the output is reasonable (mine is hidden under the dashboard of a classic car and the output is every bit as good as the old non-classic car radio.I downloaded the Whuzi Audio App but had difficulty setting this up - but it doesn't seem to enhance anything so hardly worth bothering.Overall it is a neat and compact solution if you want to keep your classic car looking authentic yet still have music and radio.

I bought thisto fit into my old classic car. Set up and test at home using correct 12v input and correct speaker it works well. Nice quality sound, good bluetooth pairing and enough volume for a car. For the money I am quite impressed. No instructions but videos are on youtube.

It’s very compact, which made it easy to find a place for it in my classic campers van.I had a modern radio in that looked wrong and an old mono radio that did only MW and SW.I was going to get it converted into a modern one, but that was very expensive. I thought I might as well give this little thing a go.Its brilliant. Very loud and connects instantly to my iPhone so I can use it for Sat Nav and music.The best thing is now my dashboard only has the old radio in but now has all the convenience of a modern one.I’ve only got it connected to 2 pretty basic but good speakers so I’m not sure what the quality would be with a bigger system, but it’s just as good as the £150 DAB radio it replaces and a little louder..EDIT:I bought a second one for my car and it was no where near as good as the first one. I put it down to my speakers at first, but when the unit stopped working I swapped it for the one i bought for my campervan. The difference was amazing. So maybe there is a chance not all these units are the same or some have a fault. I'm going to buy another as they are very cheap and hope I get one as good as the first one i purchased.

Tiny little amp that works well without some of the annoying flaws that others have.The Bluetooth on this amp is brilliant, possibly the best range of any Bluetooth device I have ever had, can be the other side of the house and no drop outs.No terrible Bluetooth connection announcement either, some if these things have a horrific Chinese / English voice at full volume when you connect a device.Not this.Sound? Perfectly adequate with a old pair of mini system speakers.Highs and mids are clear and crisp, the only trade off is a slight flatness to the low end.But it's perfectly musical enough, and certainly better than some of the earlier one chip amplifiers.Recommended.

If you want a flexible bluetooth power amplifier buy this with confidence.I used a laptop computer charger to power the unit. This was 19vPlugged into the unit directlyConnected 2 Hi Fi speakers to the unit and switched on.Powered up without any problems.No buzzing, hissing or poppy.Connected to phone instantly with no problems.Nice clear audio.I am not stating this is a class A power amp but I do not think you will be disappointed. It sounds excellent to the normal person.Sound quality at 19v was very good plenty of volume with good treble and base.Impressive for price.Unit does come dissasembled but only takes 10 mins to assemble with supplied screwdriver. You also have to stick the heat sink to the power cpu. Easy... 👍

Easy to build, nice and small.When connected to Bluetooth (Phone and Laptop) the audio quality isn't great. Overly compressed and foggy sound, unable to correct for this with EQ on devices. Wouldn't buy again.

Nice One

I use this with a 12V lead acid battery and a couple of 8inch PA speakers for a low-cost mobile PA. It's very good and does almost exactly what I need. Sound quality seems fine to me, but my application doesn't demand hifi. Bluetooth works flawlessly with my Android phone.I haven't managed to get my windows laptop to use it via bluetooth, but it's possible that it's user error - I didn't try very hard because I just used an aux cable instead.My one issue with it is that I haven't found a way to make it disconnect from the currently connected bluetooth device to allow a new device to be connected. I can tell the connected device to forget this connection, and then connect another device. That works but can be inconvenient if the connected device is sitting around the house somewhere and belongs to another member of the family. Ideally I would like to have a button on the device, as a lot of bluetooth speakers do, that made it forget the currently connected device and advertise itself for pairing.
