Hosyond 200W Bluetooth 5.0 Amplifier Board TPA3116D2 100W+100W Stereo Dual Channel Mini Amp Board Audio Receiver for Home DIY Speakers

I’m surprised this little guy cranks out some legitimate power. My buddy traded me some outdated new in the box Sonance outdoor speakers. I didn’t expect much from this Bluetooth receiver/amp but it plays continuously and clearly. I haven’t turned it all the way up but I’d imagine it would drive my speakers just fine. Music is very clear and the Bluetooth signal extends further than the product description states. I couldn’t be more happy so I purchased another to drive bass shakers in my recliner. I would definitely recommend these to anyone with space limitations and a few speakers that need to be driven. The price point is incredible but you’ll have to assemble it. I used a serving tray because the parts are very small. Be sure to get a 24v 6 amp power supply and you won’t regret your purchase.

I made a little portable bluetooth speaker box using this amp and a couple Dayton Audio ND65-4 drivers in a ported box. Nice sound and amp has enough power to push those drivers. I am using a spare 19v 4A power supply (from an old laptop I think), so there is plenty of headroom. I am only using it on bluetooth (actually removed the au input jack) and connectivity works perfectly fine. Pairing and use is easy, and has a range of *at least* 20 feet, even through a wall or two. The 2x100w specs are a bit overzealous though. Expect no more than about 55 watts RMS on both channels on 4Ω load with a 24v 5A power supply at no audible distortion. If you use a lower power supply voltage (or not enough current capability), the amp output will be reduced. Refer to the TAP3116D2 datasheet for full details on true RMS output vs power supply voltage vs distortion vs speaker load. I made my own mounting plate for the amp and the power input, so I did not use the case plates it came with. This made the amplifier footprint even tinier than in the product pictures. I ran it installed in the speaker box at a good volume for 20-25 minutes and it got barely warm, so efficiency is good (which means little wasted heat on the amp itself).

UPDATE. 1ST REVIEW IS BELOW THE LINE. After wanting to do a refund the seller begged me not to and he said he'd send another one. Both amps sent to me failed. One lasted enough for me to hear music and it sounded nice. Unfortunately it was brief. they go into a loop and become useless. They also spark. The second one failed only 1/3rd the way into a song. I never went above 1/3rd on the volume and he ok'd my speaker and power source. I have since found out these are just a few dollars on AliExpress. I am done playing with them, they are junk and you need a $50 power supply to run them, at that price, i'll buy something that I know will work and be able to use. I will never purchase from this seller again. I will never purchase these amps again. I threw away a 500w one I got from Ali Express for $5 simply because I've had enough. I have no intention on buying 2 70v power sources for that one and I want quality stuff. Experimentation is over, FAIL. Not pleased, not happy, very disappointed. ------------------------------1ST REVIEW DOWN BELOW------------ A. Nice customer service, the gentleman helped me out, found out it was too low of a power supply so I swapped it out. B. Got it working but soon after it would turn off and on in a loop (I didn't get much use out of it until this point, maybe 30 minutes total play time) C. Quit playing with it for a few days and when I went back to insert power cord into it, it sparked. This was while it was in the off position. I really wanted this to work but it simply doesn't. The 30 minutes I did get it to work, it made my 20 year old 10" woofer in my JBL tower speakers sound amazing while only up a little bit, I never tried to max it.

This product, though slightly larger than a business card, has absolutely astounding sound quality. I'm using two 4-ohm speakers that operate well with this setup. The amplifier is powered by a 24V, 4.5A power supply, which works extremely well. I initially tried a 12V, 5A power supply, but it didn't provide enough power and caused sound distortion due to the high demand from the speakers. All in all this is a very worth while low investment amplifer for general listening purposes. I bought it to modify a bluetooth speaker I have, but after hearing it on my audio system I think I'll use it for that instead. Great build quality with easy to use volume controls. The Bluetooth works well and so does the auxiliary input with no distortion. Very simple to put together and assemble. Love it.

I used this to replace a 25W/ch device. The two are the same size, making the swap out easy, and now I have higher output without distortion. However, the DAC noise is noticeably higher on this unit than the 25W/ch, even at comparable output. I've tried reducing the volume knob. It has so much gain that there's plenty of power even at 1/2 range. But the annoying DAC noise continues and is especially prominent when music is at soft (classical music). I also tried swapping out 20VDC and 12VDC power supplies, but no change. Due to the noise, I'm not sure whether to give it 3 stars or 4. It's still a great value for the money, especially if you have speakers and a DC power supply already.

I bought this and used it to retrofit into the original AM radio in my 1963 Ford Galaxie, and it works great! I made some adaptors to use the stock radio knob and mount the unit inside the gutted radio and its small and light enough that it was super easy to fit and I bet you could fit this little guy into a lot of things. The iphone noises for the on chime and the connected chime really bug me (I would give 4 stars to have a regular beeping noise instead) but for how cheap this thing is, I guess I'm not too surprised. This little thing honestly packs a pretty good punch, with just two 6x9s, it is loud enough to hear over highway speeds with the windows down and straight pipes at only 75% or so.

I used this to upgrade my 1971 Chevy g30 radio. Easy setup and good sound quality. My only small issue was that I wanted to run the aux cord through the tape deck so I could connect it to my phone to listen to FM. But the aux cancels the Bluetooth function. Still happy with the results though. I can live without radio as long as I have a way to stream my own tunes :)

Used this to convert my 1972 Ford AM radio to a Bluetooth receiver. Works great! It's not a high power stereo system, but does a good job getting tunes in the old car. Seamless connection a d easy install for the most part.
