XRONG Wireless Audio Subwoofer Amplifier, Audio Bluetooth 5.0 Stereo,2.1 Channel Mini Hi-Fi Class D Integrated Amp 100 Watt x2+100 Watt for Home Outdoor Passive Speakers,Powered Subwoofer

I will say that this works really well with my speaker system. In terms of size, it is decent size and it works pretty well. It is great for my living room sound system. It does require some setup to your sound system and subwoofer. After you complete the setup, it worked right away. The sound quality this can produce depends on your sound system but I do think this gives amazing sound quality. It very clear and powerful sound. It has a very simple control on the device. You can also hook up to this via bluetooth. You can put it anywhere near your sound system and are able to connect to it wirelessly. The sound quality is not even effected with bluetooth connection to my computer. Most of the time I usually have movie night and the sound is amazing. It can be really loud giving you the immersion experience you want. The controls are all pretty simple to control. The front is just knobs that control tremble, bass, etc. It does come with wires so you are able to connect to your speakers and such. It is pretty well made. It does not use cheap plastic as the shell. It is still fairly life. Overall, this is a good amplifier that you can use for your speakers. I use it for my living room. You will get a pretty good sound experience and the system is very easy to setup and connect to. The black finish is nice so it fits my decorum pretty well. It has a simple style.

Right channel is way quieter than the left, bass & treble adjustment are labeled wrong & for some reason “trebbel” is like 500hz & up so it seems like a second volume knob, sub crossover is nice, works good but this thing is a disappointment, it is however loud & appears to be pretty clear

I'm glad it came with its own power supply however Left channel is louder than right channel it's kind of annoying and the switch that I thought was going to be a toggle switch between Bluetooth and AUX.. which would have been nice for when I shut the system down via power strip at night or when I leave the house to save electricity every time I turn everything back on I have to make sure I hit that button to switch it from Bluetooth back over to AUX my TV works off of RCA for sound to the receiver so I was hoping to keep it on aux all the time but no I have to get up and manually select over

Got an outdoor sub for xmas, and got this to drive it. Was very plesantly surprised .. the sound quality is decent and it handles standard 200W outdoor speakers no problem. My only NIT is that to change from "direct-connect" to "bluetooth" .. you have to unplug the 1/8 cable. For fixed use this isn't terrible; but if we're having an event and I want to goto BT; sort of annoying to reach in and disconnect.

So, it sounds pretty good, and there are some decent amount of control knobs, and the price is right for sure, especially considering they include cables too... but it had one annoying flaw that had to make me return it. It always kind of "fades on" the audio. Fine if you plan on using it for a speaker system for music only, but since I was using it for my pc, it would only play back part of notifications that would come in, which got very irritating over time. Eventually I went with a dayton audio amp that did the same thing as this one but didn't have any fade in issues. So, I would still recommend this as a general amp for your garage or patio or something, but not the best for pc use.

Sound is good. Even poor quality Audio/video sounds great compared to high end receivers as high end receiver needs more calibration. Bluetooth connection is very good. The only minus is sound is not enough to drive 8 Ohm higher wattage speakers. Very good for small room setup.best Quality less price

The media could not be loaded.  This device looks nice. Knobs feel smooth turning. Bluetooth paired quickly to both my iPhone & iPad. The volume is limited to the output of the device it’s paired to. My iPad Pro puts out a louder volume than my iPhone so the volume with the bluetooth amplifier reflected the same. In the video you will see that the treble adjustment acted as a volume control adjustment so there were actually two volume controls. The base adjustment worked okay. All of this can be seen and heard in the video. Overall if it worked I’d say it’s a bluetooth amplifier geared more toward a TV or music source to get the sound closer to where you need it rather than a stereo system or theater sound system where both quality and volume are important.

I cannot believe this device has that much power. I was blown away! The set up literally took 3 minutes. Great audio quality. Great built quality. Threaded connectors! I'm glad I was able to get this product. TOTALLY RECOMMEND.
