50w+50w amplifier board

Does exactly what I hoped. Small enough to tuck into a subwoofer or PC case, and produces good clean sound. I'm running 4 inch Polk bookshelf speakers, using a 12V DC wall wart., and very happy. Highly recommended.

It has only been a couple days. But so far I am really pleased. For the category, it is not one of the higher output units, but it is plenty for what I am doing, and sounds clear. The multi-function dial is nice, and it will turn off the unit. The on-off function is great for a battery powered device build, so no extra power switch is needed.Edit. It appears the on off function does not complete turn off the unit.

I use these to drive 4" full range speakers in arcade cabinets. They are plenty loud enough with the volume at no more than 10%.

Shows as connected, but no power is coming out of either speaker terminal. I checked with a voltmeter after trying two different speakers on both terminals. Nothing. No idea why. Will return.

It was a lot smaller than I thought, but it packs a punch. was a perfect replacement for the amp that died that i use connected to my computer.Sounds good connected to a pair of old radio shack Optimus speakers.The android app will not install on my moto g power Android so i have no idea how the extra features are?

Works great maybe to good. Very loud but does sound good

Purchased this for my Arcade Cabinet. It worked greatfor about 3 months.. But after 3 months it died on me.Started making clicking noises then eventually died.Poor quality.
