FX AUDIO 2.1 Channel Bluetooth Power Amplifier Home Audio Class D Amplifier with Subwoofer Output TAS5342A Hi-Fi Stereo Mini Small Optical Audio Amp DC 24V 4A Power Supply D502BT (Silver)

I had a couple of bookshelf speakers and a sub-woofer needing a new home since buying a new sound bar. So...I thought that my garage needed a sound system, but I didn't actually have an amp. Originally...I was contemplating buying a low end Onyko or something but then I started to see these mini-amps which many were for karaoke set-ups.Anyway...after much research I found an amp with a subwoofer out feature and bought it. It sounds GREAT and I love going out and working in my garage now. I'm sure my neighbors are wondering what happened since they probably can feel the beat of my music now.The setup to have it play via bluetooth from my iPhone was effortless and flawless. The bluetooth distance is short which was a bit surprising but not limiting enough to drop any stars on the overall rating.

I did a lot of research online before I picked this amp and it is almost unbelievable. I replaced my 500 watt Pioneer AV Receiver with this tiny box! Of course, it doesn't have all the inputs of my Pioneer and it doesn't have the power-- BUT... it has enough. I'm running optical from my TV into the box and it has plenty of power to drive my Bose speaker system. I only wish my TV volume would control the optical volume output--as it is, we have to use the FXAUDIO remote to adjust the speaker volume. We use it at 10-15 on the volume which is good for watching TV. You can crank it up a lot louder, but I don't really need to do that. By the way, it was not obvious to me, but the speaker outputs unscrew so you can run wires into the posts and screw them down. So far I have had no issues, but it has only been a week. I'll follow up if it doesn't last but so far, so good.Update-- After a year, the box is still working great. I will say the sound is a little thin, but overall, I'm happy with it. One of the buttons on the remote control stopped working and it is the volume up button. So far I have not been able to get a replacement. I tried contacting the company by email, but have not received a response.

Developed a permanent loud buzz after a short period. They wanted me to run various test before returning. I know when an amp is faulty, folks.

Just got this amp in and so far, really happy with it!Powering a set of 3-1/2" 4-ohm 50watt RMS speakers on PC desk. audio quality is great! set up is simple, Optical input works as it should, same with Bluetooth.

Short story: Good amp, gets loud, low distortion, sound is comparatively thin.Summary:I ordered two amps (this and the Fosi BT20A-S) with the intention of keeping one. I was especially excited about this one because of the various connection options (RCA, AUX, Optical and BT). The build quality is very good. It is sturdy, the nobs turn smoothly, binding posts are secure etc. Furthermore, it comes with the RCA, Aux and optical cord.This amp puts out a good amount of sound. I used it in my living room which opens up to a a dinning room and sitting room (~1200 sq ft total) and I could play it loudly and the sound was pretty clean. Where this amp lacks is in sound quality. Compared to the Fosi BT20A-S, the sound is thin. If you want quantity (loudness), this will do it. If you want quality, better options exist.To sum it up, it's a good amp, but it will be returned, simply because the Fosi sounds much fuller, much better. It's quality over quantity!

Nice little amp.But once a day, mostly when switching from one Bluetooth device to another one, when playing, the volume drop progressively to 0.I find out the Amp needs to be power-cycled to fix the issue.Annoying!!Is there a firmware update?

I ordered this to replace a 2.1 channel stereo receiver that I had connected to my pc (yeah one of the old big ones). Was a little unsure about the sound quality with it being such a small unit. but once I connected it to my pc and hooked up my speakers and sub, turned it on and cranked it up, I had a very big grin on my face. OH YEAH, I would recommend this to anyone for any application!!!!

This little black box blows me away! Have it in my work shed hooked up to 2 infinity bookshelf speakers and a 8 in. sub, remote works great, bluetooth connectivity awesome! What a space saver too!
