Doesn't even hit 50W really, fully loaded, with full 24v power directly from a good supplyDepressing. Makes me wonder if any of these TPAs are legit.

sub woofer support is the feature that sets this amp apart from others I've tested. Extending the dynamic range really makes a difference. Don't expect this to rattle the windows it doesn't do that but it adds the lower range like a sub woofer is supposed to do. I can't measure the power output so I can't say it reaches the advertised specs but it's plenty loud enough for a normal size room. I barely hear some white noise with my ear near the speaker at full volume with no input. I'm happy with the sound quality. On the down side the output coils get hot so you'll want an enclosure with ventilation the heat-sink didn't get hot just the output coils. Also the legend on the board is in Chinese so I had to search the internet to find which input and outputs were which and what input voltage was needed. I hope to hook this up to a Bluetooth module to make a home sound system.

So I got this board in order to fix the Klipsh ProMedia BT 2.1 speakers that I had. The control pod seemed to be broken bit, but Klipsh wanted like $60 + tax + shipping for it. So like a 1/3 cost of the original price of the speakers, even knowing they had issues burning out the amps and all. Bollocks to that. So I figured they were dead any way, might as well try a cheap fix just for the fun of it. Got this amp and wired it up and brought the speakers back to life.I went a extra step also, cutting it into the backplate after removing the original amp. I keep the original speaker terminals and wired those to this amp (which is inside the subwoofer box), also wired a 3.5mm male-to-female and have attached that to the backplate also. Then stuffed the power cord in there too (I need to fix it so it'll work better.It's a mess in the pics I took, I didn't want to spend too much time on it if it wasn't going to work, but it did. So next, I'm going to either replace the backplate with a new piece (cheap at HD) and get the amp wired to the large heatsink that was on the original amp for cooling, maybe I'll add a low RPM fan to exhaust too, not sure yet. But all told, $30 in parts (this, the A/C adapter and 3.5mm port) and about an hour and it's working just fine again now.The sound quality isn't as good as the original amp, that's just simple math, but it's good enough if you aren't an audiophile or have a ton of money to buy new Klipsch speakers whenever they blow out. The heatsink like other reviewers said, is just sad. But easily fixed if you are handy enough (and the Klipsch amp has a giant heatsink you can repurpose). Controls are a bit funky to tune, but once you get it right, it works. Look at the diagram the other reviewer left and you will be golden with this amp.

The amp arrived on time. It was easy to set up and get working. Problem I had was the amp and the knobs screws and nuts all came in the same plastic pouch. All the parts was just rattling around over the board when shipped. One of the electrolytic capacitors was dented due to one of the knobs being wedged between it and the heat sink. It still works just a small thing that could of made the unit nonfunctional. I ended up just using the box it came in without the top as a case for under my monitor on my desk.
