High-Quality 200W Bluetooth Amplifier Board with LC Filter Technique - TPA3116, DAMGOO 100W+100W Audio Amp Board: Dual Channel DC8-24V, Password-Free Connection to Phone for Peaceful Listening Experience Review

Nice little board, quite powerful, connects to Bluetooth very quickly. It will be a hassle to put anything other than bare wire into them, forget about using shovels, but overall a very good bluetooth speaker board

Nice little bluetooth receiver. Drives 6 speakers with no problems. I used a Boss line level shifter to connect another amp with subwoofers to it. It actually gets really loud. It doesn't have a bass/treble control, so it's a bit on the top end, but the subwoofers make up for it. Great receiver, handmade.

I used it on a small cassette speaker. There is power in this little thing! So much so that I'm going to add some woofers so we can't blow the 3.5-inch Dayton speakers it contains. Bluetooth works very well! He went through the house to the bedroom and was still playing. Even when the caravan is closed. The wide voltage range is great. I bought an adapter and powered it with a 20V Dewalt battery.

The DAMGOO seller takes care of his customers and goods. They took the time to contact me and resolve the issue I was having below. I have driven 6x9 in my adaptation in a vintage car. I played around with different voltages to get clarity on the upper limits of the volume control. Although it operates at a lower voltage range I would caution you against going up the voltage if you want the best performance this nifty little amp is capable of. Very cool idea. Unfortunately you get what you pay…

I bought this particular Bluetooth Amplifier because of its power rating with a 24v power supply at 8 ohms. WOW! I am completely satisfied with the volume and quality of this amp. The Bluetooth range is amazing. Line of sight range is over 100 feet with my Samsung Note 10. My wife can only get about 30 feet on her Note 8. I also appreciate the nice tones that indicate a BT device is connected or disconnected. I have used other BT devices with loud and unpleasant display tones. I installed this…

This little device blew this IT guy away. It might not be for the audiophile as it has decent sound quality to me, but with the 1.5A 24V adapter attached it drives two classic 120W Pioneer 10" speakers LIKE AN ABSOLUTE MONSTER on! Its size and power output will surprise you. Nice! The overall volume for computer speakers with a vintage Pioneer 120W set is off the charts! I smoked 2 Pyle BT 2 channel amps in 5 months on these old pioneers. But this beast just eats them up and asks for more…

I bought some cheap circuit boards to test bass transducers and this unit definitely deserves a mention. Firstly it is packaged and built really nicely and looks like no other when everything is put together. Bass reproduction is better than other tested devices. Of course you can't expect massive bass from something that wasn't designed for subwoofers, but in testing this drove the AuraSound AST-2B-4 kit adequately, although it did get quite hot in the process, but if you're using smaller…

You are connecting 9-24 VDC to two speakers that may be 100W each. This works great with a variety of 2x 6 inch speakers in the wild. You need a DC power supply with fan (200W, ideally 24V > 8A) for full power audio. POSITIVE: The absolute best feature is the brilliant Bluetooth implementation. No delays, interruptions, warnings. Most, if not all, of the information tones are short chirps. It lowers the volume for warnings, doesn't cut the audio stream. Turning the volume knob/potentiometer…
