This is a very good and compact amplifier. If you want one for a DIY project this is one of the best. When I turn it on however, there is a very annoying voice with a heavy accent telling me bluetooth is ready to pair. when at low to moderate volume there is no background noise even when not playing. When the package arrived, the power jack was not connected, fairly easy to solder back on though.

Good: Easy to set up, just power it on, connect to it from your phone and start playing. It's plenty loud at 24 V input. Plays 6.5" subwoofer very nicely. The subwoofer crossover frequency adjustment is a good touch. Bad: The speaker output is riddled with noise from badly designed PCB. Digital signals are clearly leaking to the analog section of the amplifier, causing unwanted "cell phone near a speaker" type noises to be heard. The BT receiver switches off its analog output when it detects no audio is being output, and this eliminates the noise. But once anything starts playing you hear the noise again. When listening at moderate to high volumes, actual music overpowers the extra noise though. It's sensitive to power supply noise as well. I'm currently using it with a 24V 120W Meanwell medical switching power supply and can hear the switching noise coming from the power supply. Preferably use a toroidal transformer or batteries to avoid PSU noise. Verdict: You get a lot of your money, so I don't think I can't complain. But if you wish to use this receiver/amp combo for any serious listening, don't even consider it. For a party blaster for which the only requirement is loudness, this is perfectly usable.Read full review

Loud, yes, does somewhat what it claims to do but it does it in a sucking way. The signal to noise ratio is absolutely awe full. And to hide this design mistake (which should never have made it to production stadium) they have built it so that when the signal is low, for example when the Song ends they cut to output to the speakers. This in turn is slow to activate the speakers again when next song starts And on top of that the same annoying voice echoes when you turn it on as the same other low budget amplifiers. “She blutothes device is ready to paaaaair” Please don’t buy! Stop this crap now.

I have used it as a home cinema amplifier replacement. + It was easy to assemble and it performed good. Sound was nice and clear - It has no bluetooth thought it is written in title. Subwoofer channel broke down after 2 weeks.

The inputs on this amp are great. usb, sd card, aux, and B/T! Plus its 2.1 speakers and sub, 50w per speaker and 100w to sub! 200w! Best unit for the price I have found so far. Could be sturdier built and nobs are kinda cheap.
