50W+50W Bluetooth 5.0 Amplifier Board,100w Audio Amp Board Dual Channel DC8-24V,Easy Installation and Password Free Connect to Phone Quietly

I recently purchased the DAMGOO 50W+50W Bluetooth 5.0 Amplifier, and it has exceeded my expectations. The sound quality is crisp, clear, and surprisingly powerful for its size. It easily drives my speakers, delivering a rich and balanced sound with plenty of volume. The Bluetooth 5.0 connectivity is stable and easy to pair with my devices, allowing for seamless streaming from my phone. I also appreciate the sleek design and compact size, which fits perfectly into my setup without taking up too much space. Overall, the DAMGOO Amplifier is a great choice for anyone looking to boost their audio experience with reliable performance, modern Bluetooth capabilities, and excellent sound. Highly recommend! Pros: Powerful sound with great clarity Stable Bluetooth 5.0 connection Compact and sleek design Easy to set up and use Cons: None so far

Very respectable little amp. Truly no complaints: I’m always satisfied when things do everything they’re supposed to and nothing they don’t need to. The Bluetooth is a good strong connection with surprisingly low latency compared to other more expensive systems, the sound quality is very clear and transparent. Maybe a little bass-heavy but there are other variables in my system and I can't conclusively blame it on this. Works well with a typical 12V AND 9V power adaptors, and the potentiometer seems decently sturdy for the price. Unless you’re hooking this up to super expensive speakers, this should suit anyone’s needs within the speaker Ohm and input Voltage specs.

For the very low price I was expecting mediocre BT & sound quality at best. I am very pleased that the stability of the BT connection is great, the power output (with a good power supply) is shocking and the audio quality is very satisfying. It does not compare to my home theater in anyway but for the price it is amazing. I immediately paired it with my phone and later tried the aux port and couldn't get it to work. So I sent a message to the vendor who replied within hours and explained that I needed to disconnect the BT then it automatically switches to the aux input. Now that I know how to use it, it works great on both BT and aux. I just ordered a second one for the garage.

This very inexpensive little amp can produce very clean sound, but it is not as polished as the more expensive Class D amplifiers that I have used. With wired connections to a portable MP3 player or computer it produces clean sound, but when wired to either of my cell phones it produces a weak signal with a lot of hiss. This hiss appears to be on the input cable and can be heard on headphones if the signal is split to serve both headphones and this amplifier. The amplifier appears to put a DC bias of a few mV on the input. The Bluetooth connection from the cell phones worked well. Unique to this class D amplifier compared to others is that it draws a little under 10 watts of wall power when idle. This small power in a small device makes the whole assembly warm to the touch. With the loudest signal I could find I could not get the amplifier to draw more than about 25 watts of wall power. While this sounds small it was enough to drive a pair of baby advent 8 inch acoustic suspension speakers loud enough that I had trouble hearing myself shout. Larger speakers would produce more sound with the same amount of power. Overall it is a mixed bag. Because of the issue with the cell phones I am unsure if it will work in all the situations I might intend to use it. But when it works it works well.

Awesome base amp for builds , clear no distortion, very tiny footprint , lower power need . Didn’t hear any noise only Song .

Hard to beat the sound quality for the price if you ask me. I'm not a self-described audiophile or anything, but I have a decent ear for when a stereo sounds good or sounds like junk, and this sounds quite nice to me. I'm using it with a 5A power supply and a basic 3.5mm audio cable plugged into my computer. I connected it to a pair of Philips bookshelf speakers that I got years ago with some regular speaker wire and it sounds great. I can crank the volume plenty loud with no distortion, sounds clear. I just slapped the board together with the included basic frame and put it on my shelf. If I wanted to build an enclosure for it, or integrate it into a portable stereo or something, it looks plenty amenable to that, with decent mounting holes and a panel-mountable volume knob. As others have noted, the Bluetooth functionality works just fine, sounds good and such, but the amp will stay connected and your device will keep "playing" to it even if you turn the volume knob all the way off. I don't usually use it with Bluetooth so I don't mind, but it is a minor annoyance having to disconnect your phone manually when you're done.

I have 3 of these hooked to 3 pairs of Dayton Audio TT-25 and BST-2 shakers, all powered by a Meanwell 360w power supply. Fed by a Startech USB Sound card this setup is super powerful and substantially more cost-effective than off-the-shelf stuff. 10/10 as far as I'm concerned. A super simple and easy to use amp for lower powered situations. I will be snagging a couple more to build a 4 ch speaker setup for my sim rig very soon

I swapped out the soggy old amp for this nifty little number and tucked it into a watertight box to avoid a repeat performance. Snagged some banana connectors from Amazon, and after a bit of DIY drilling, we were in business. Right now, it's a solo act with just one speaker, but I'm scouting for its partner in crime. It's a 70-100V speaker that moonlights 8 Ohms passive on its days off, and guess what? It's working like a charm. For the cost, I'm over the moon with this mini marvel. It's cozily nestled in a Rubbermaid cabinet right under the speaker, staying dry and making waves. If you want to get the full 100w or 50W+50W, I suggest getting the highest voltage DC power adaptor compatible with the amp. I had a 9V adaptor and it worked but when I got one with full power it made a lot of difference.

Good little bluetooth amp. Decent build quality, and the bluetooth connectivity seems very good. The only problem is the slightly noisy volume pot.

Utilizzato insieme ad un alimentatore è una batteria per trasformare un paio di casse altoparlanti in sistema audio wireless. Pro e contro: il bluetooth non ha password di accesso perciò ci si può collegare facilmente.

Funciona como se espera, estoy usandolo con dos altavoces de 50W @ 6 ohm y es muy buen sonido, sin tenerlas al máximo y en una habitación pequeña, no he probado la entrada de 3.5 pero con la bluetooth es suficiente. no hay distorsión ni ruidos.

Kann meine Uberaschung gar nicht in Worte fassen. Ich haette nicht gedacht, dass so ein kleines Geraet meine gigantischen Boxen ansteuern kann und dabei noch so gut klingt.

Muy buen amp. Tuve que comprar tres previos y no daban el ancho. Buena calidad 👌 mucha potencia.
