DAMGOO Bluetooth Amplifier Board,50w+50w 2 Channel Audio Amplifier Board Suitable for retrofit Speakers Bluetooth Speakers,Easy Installation and Password Free Connect to Phone with Protective Shell

Update 9/12/2022 The original unit purchased 8/5/2020 still works great. No problems at all. It works so well I bought a second unit this summer for our summer place. It also works great. Original review: It does everything it says. The sound is crystal clear and way loud enough to hear outside on our deck with two Yamaha 8 Ohm speakers on a busy street. I connect to the unit via blue tooth from my phone. So far, it's connected each time since the initial pairing without a problem. I do power the unit down when not in use. When powered up, it beeps first to says it's up, then a second time when it makes the blue tooth connection. I have not attempted to push the sound up as high as it can go as I'm sure my neighbors would not appreciate it. :) I have recommended this to others. I can't say anything about quality or longevity as I've only had it installed for a few weeks now.

It works perfect as a replacement for my amp to my Fender Frontman 15r that died a ways back. I put a 8" Celestion speaker in it last week and it sounds great. I am going to buy a second speacker and build a box the same sixe as the fender box and run speaker cable across to it and power both off of the amp since I am only using half of them. If I had the money to spend I would be building all kinds of audio projects with these. I love this little but powerful amp that is perfect to double as a Bluetooth for my computer and amp for my guitar. Vollume is a little difficult but not too bad. For the money this thing is awesome.

This little board is bad ask.lol. Worth every penny ..the power requirements are versatile...5-24vdc. I have powered it up all day with a 20 cordless tool battery. It has yet to use full charge in an 8 hour day. It runs two 8" And two 3" speakers in a four foot custom box and the sound is incredible..I was very surprised at the clarity and range ..excellent bass excellent mids... excellent highs. I have intentions of setting up another board with a amp board and crossovers to drive a couple 12" and horns for an old fender system the Bluetooth has a decent range at about 30' solid and connects easily. I promise you won't be disappointed with this board. Easy to install in any application..the stand alone power is more than adequate for most applications ..I often turnine down as it's loud enough to disturb the neighbors..

after thinking a bit...moving it up to 4 stars... it works well for the price so four stars... I was frustrated while trying to listen to an audio book... there are lots of low voices and starts and stops and background noise. For music it's pretty good. amp works, it's loud, enough for my room, but if you listen closely, there's always a hum when the sound starts up..... ok for the price because of that.

I've bought 3 of these boards and made these cabinets with 4" two-way speakers. I've used Kicker, Rockford Fosgate and Polk speakers and all have resulted in excelent sound quality and volume. This board will pair with your phone in less than 5 seconds after turning it ON. It is really amazing to get this amount of volume and clarity from such a small device. I use mine with a 12v Ni/Mh battery so I am not even using its full potential.

Connectivity to speakers and Bluetooth was easy and works with no problems. Connected to a couple of ceiling speakers and sounds fine to me. I'm currently listening to a thunderstorm which had my cat a little confused. I'm using a 12v dc power supply and it's plenty loud enough.

Perfect awesome sound for its size. Worked great in R.C. car

Easy device for use on regular speakers and cover to Bluetooth

Poco prezzo ottima potenza si collega benissimo a qualsiasi telefono tablet proiettore

Der erste gekaufte Verstärker hat super funktioniert. Deswegen habe ich noch einen Zweiten gekauft, eingebaut in eine Lautsprecherbox. Der kam gleich erst einmal zertrümmert bei mir an, siehe Bilder. Eine Ferritdrossel ist zersplittert, der neben der Drossel angeordnete Elko ist halb herausgerissen und steht schief. Hier muss es massive Gewaltanwendung beim Hersteller gegeben haben, weil die gesamte Verpackung völlig in Ordnung war. Es handelt sich nicht um einen Transportschaden, traurig. Diese Sendung geht umgehend zurück. Die Ersatzlieferung war nun wieder in Ordnung. Das ist ein sehr gut funktionierender Verstärker. Ohne Ansteuerung gibt es absolut keine Fremdgeräusche, Rauschen oder Brummen. Einziger Nachteil: Wenn ein Klinkenstecker eingesteckt wird muss Bluetooth über den kleinen Leiterplattentaster aktiviert werden. Wenn kein Stecker eingesteckt wird läuft über Bluetooth alles automatisch. Prima Teil um aus normalen Lautsprechern Aktivlautsprechrr zu machen.

Not sure why it is so cheap but does a great job on my little hifi speakers running at 12v with a spare power supply that I had. Stuck it on with double sided tape and have a decent pair of active speakers. Bluetooth connects really well with no problems. I recommend setting the volume on the device lower and then using the volume on the laptop but you can play around with both levels to see what works best.

Buen producto. Facil instalacion y buena calidad de sonido. El bluetooh conecta super rapido.
