Bluetooth 2.1CH Amp

I have a powered subwoofer in which the amplifier stopped working. I rewired it to plug into this amplifier and it actually works better than the one that came installed with the subwoofer. Although I've not tried it, I think it can also function as a full-range amplifier.

Opened it 5 minutes ago and it's already back in the box ready to hand back to the UPS guy. Knobs were backwards or upside down. Didn't seem to do what they were intended to do. I'm giving up on these little amp money grabs... this was so disappointing. But now I'm over it. Going to just get a normal 2.1 home receiver and be DONE with all this wanna-be BS. I have been waiting two weeks between two other little amps and I'm still having to return stuff right when I get it. No more I'm so drained and I should have just got a regular receiver from the very beginning when I decided to use home speakers for mu computer. Just so tired of the cheap crap everywhere. Sorry. Ranting. Done now. F-ing DONE.

Item is good, but the printing on knobs are misprinted and doesn’t control what it say they should. Lastly when connected to bluetooth the bright blinking red light get annoying after awhile.

I wanted an audio setup for my PC that was better than my old Logitech desktop speakers + 4" active sub, but I didn't want or need anything expensive and high end and while I appreciate good sound quality, I'm not an audiophile by any means. So I bought a couple of modestly priced 4 ohm bookshelf speakers, an inexpensive 4 ohm 6.5" passive subwoofer, and this amplifier. I use the line outs on my USB audio interface into the amp and wired up the speakers as normal, and it works really well! Setting the amp to half volume and using the monitor level on my interface is perfect for going loud without distortion and quiet without loss of clarity.It's worth noting that these can be had for much less on AliExpress, but I wanted fast delivery and an easy return in case of problems. But I still think it's a good value and perfect for anyone looking to up their audio game a bit without spending a ton.

I spent too long trying to get this amp to work and missed the return window. The main problem was the left channel had almost no high frequency. I was using a new (for me} pair of Infinity Bookshelf speakers. Thinking it was the speakers, I tried swapping tweeters and crossover capacitor with no difference. Swapped left and right speaker wires at the amp and the highs moved over to the left and right highs disappeared. Opened up the unit to look for anything obvious and found nothing except a lot of loose hardware and flux on the solider connections. Cleaned and tightened with no change. I also noticed that the Treble and Bass knobs are labeled backwards which is not a show stopper. Otherwise the right channel and subwoofer output sound good. I would have liked to use this amp, if it had worked properly, it has all the features I need. Now I have a $60 paperweight.

I'm a huge music fanatic, so I love blasting my music loudly and crisply, especially coming home from a long and tiring day at work. This works wonderfully for enjoying my favorite bands at bass-thumping ear-deafening volumes. It does require a stereo system in place (subwoofer & speakers) but was really easy to hook up to my current system. The light glows a dull red while the volume is turned on, but flashes to a vibrant blue when turned on. It blinks while searching for bluetooth and is found under the name AMSK when searching to pair. I loved the ease of use with the dials as well as the option to use an AUX cable if Bluetooth isn't available. Stellar device and I'll be enjoying my heavy metal, bass techno, and vocal pop for many months to come!

Constant whines, and drop in quality of audio. Sounded like a Bluetooth signal from 10 years ago. I got the Fosi equivalent which did cost more but is much better quality in sound and build. Would not recommend purchasing.

I finally got around to testing this. It is a small but very well made device. It feels solid and looks good too. I had issues with the cable connection to my 12 inch subwoofer so I tried this amp. The Bluetooth connection is solid and the sound quality is very good. I have not tested all the functions and connections but so far this is fitting my needs. I will do an update when possible.
