Mono Sound Speaker Amplifier Module Single Channel AMP Board Power Amplification Board 12‑24V 5W‑120W TDA2050

The media could not be loaded. The perfect device to reuse the gen 1 echo speakers and PSU! I use it as a mono speaker to reference my music production/have a speaker for my Yamaha DX7.Definitely reference the original pictures to make sure you get your psu polarity correct and double check your polarity on the input lines.Also seems like an economical way to get audio in your car if your head unit doesn't work and can tap the 12v DC line and ground.

I bought this item as a replacement for the output stage in an old tube type guitar amp. With the price of output tubes topping $300+ for a matched pair this item becomes a very cost effective alternative. Sound quality was surprisingly good for such a small package. And boy does this amp pack a punch, more then enough volume coming from the two 12 inch speakers connected in parallel providing a 4 ohm load. I'm currently running the amp with a 15 volt DC power supply. The item is small and built very well. The terminal connections are marked but polarity is not on the DC connection. Be sure to connect the DC power so that the negative is connected to the terminal closest to the DC IN label on the board. Another plus with this item is how cool it operates, generating very little heat while pushing out the sound. All in all, I am very pleased with this product and far exceeded my expectations.

It was exactly what I wanted

I’m using this to drive an 8-inch guitar speaker in a small practice amp i made. It’s clean it’s quiet and can produce a good volume when turned up. I’m using a 20 volt dc ps. The only thing I’d caution you on is to be gentle with the volume pot. It seems a little fragile since it’s just mounted on the board. Otherwise this is a great little amp, and no soldering needed.

perfect for my application, it's small size and ample power made it perfect.

Really? No labels on the board whatsoever. Print out the image that shows all the connections labels and polarities or who know what may happen when you try trial and error.

First time use at 12V 1.5 amps the board caps blew and fried my $160.00 audio input device.

My security system has composite out for audio passthrough. So I needed a mono class D amp for a boat speaker I came across free. I hooked a 1 amp 12v brick to a switch then this little amp as its only a 25w boat PA bullhorn & I dont want to scare anyone or cause hearing damage. Will be fun to play the Michael Myers theme for the kids this halloween when they come for their treat lol.
