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.

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.

Actually works very well. Building case now for a mini sub.

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.

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.

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

Hobbyist here, trying to use this with a thrift store speaker; testing showed it could only handle 37 watts which is what the specs for the chip are documented as, after looking it up. Worked for intended purpose, but took stars off for not matching the item listing.

Using it for a guitar amp with a small speaker. Works great with no background hum. Clean sound. Use a good power supply if you want good power with no noise.
