Nobsound 2.1 Channel Hi-Fi Bluetooth Power Amplifier, Mini Stereo Audio Amp with Dual DSP, Subwoofer Output, Desktop Mini Size, Home Theater (Q100)

Currently used this amp to revive my computer audio experience. I had a set of Samsung speakers that the amp had died on years ago that I used with this amp. The left and right channels are two 4 ohm speakers in series, and the sub is the original 5.1 amplifier. Judging by how much power this amp puts out, I would say it's pretty great for any location you'd use a set of bookshelf speakers and subwoofer for.Clear audio output, and balancing the subwoofer is fairly easy with the bass buttons on the front. I haven't turned the speakers up loud enough to hear where the distortion is, but I also wouldn't be comfortable being deafened doing it.The build quality is also quite nice, all the buttons are tact switches, and the knob is a rotary encoder, so it shouldn't go bad. It also has nice rubber feet for dampening, and doesn't get that hot during use.The only flaws I can see with the amp are the aux input on the front and the bright volume display, however neither of those bother me.Great value for the price. Totally worth it over any modern computer speakers for sale today, especially due to the size and speaker customization the amp provides.

This small unit is awesome. The power supply unit that comes with it is more than enough for mi set up. I have two bose cubes and a Bose accoustimass 25 sub that i remove the amp from it due to some hum noise. Bass is deep. Mids and highs are clear as well. When there is no sound, the amp makes a very low hiss, very low. When connected to a Bluetooth device, it also make a low hiss sound, nothing that will discourage me from getting me a second unit.

I purchased 2 of these back in mid may 2023. I unboxed and used them a week ago, everything went smooth until I tried to add bass to the subwoofer which was the only thing it was powering up and it it immediately went into protection. I thought maybe it needed to cool down. I pulled out the second one. Same result, not only that whether you have speakers wired to it or not the power supply gives off a pretty big spark when you plug it in. Initially there was a green led then it went to a blinking red led. It tells you about the spark in the directions but I was extremely disappointed in the amount of power and performance. Maybe there are grounding issues with this device but i went through 2 in less than 10 minutes and that is definitely unacceptable. I am Powering 1 “10 monoprice passive sub and am using 14awg. No way this thing handles 100w. No way.

Good product, nice slim design gets a little hot. Good sound, my main gripe is that when I turn up the volume on my phone to 100% it distorts the bass. Not sure if this is my phone, amp, or sub, but it is the only thing wrong.

There weren't any reviews of this product when I decided to purchase it, so I'm leaving one. This item is exactly the product I was looking for, so I bought one without seeing any feedback about it. The amp on my Klipsch pro-media 2.1 speaker set was failing (only one side worked and the other side speaker wire connection was broken, and the subwoofer was missing half of the foam rubber surround which made is sound terrible), so rather than replace the whole set I decided to use this amp to power the speakers instead. So far the only fault I can find is that the auxiliary input plug has to be manually unplugged before it can play over bluetooth. The volume display LED it pretty bright at night, so I find myself turning it off when not in use. This is probably a good thing for the life of this small amp anyway. I will update this review if the amp dies anytime soon (purchased 07/19) but if it lasts 10 years I would buy one again. This isn't the right choice for an audiophile, but I doubt any would likely choose it anyway. It sounds ok, loud enough without any distortion after fixing input levels. Bass sounds good now that I have replaced the sub that was bad. If you are looking for something cheap to power some extra speakers you have lying around, you probably won't be too disappointed. It sounds as good as the Klipsch 2.1 pro-media system originally did, and better than any complete speaker set I could have purchased for the same amount of money so I am happy with it for now.

Overall it seems like a nice little unit.I like that it has a third channel for bass.Sound is okay,no buzzing or anything.Loud enough but not going to blow my little speakers or anything,sounds louder with a bass speaker.I like the volume display,goes to 31.Sparks really fly when I plug it in,I suspect it is the cheap power supply but I am not sure.Regardless I would not walk away and leave it plugged in.I am returning it.

This amp works amazingly! It has no background buzzing like a lot of chinese amps do. The subwoofer aspect is SUPER powerful. I believe it is close to the power rating claimed. I've got an old 12" JVC 100w rms sub hooked to it and this amp moves it with absolutely no problem!

Love the product good quality. Great sound The only down side is that it gets over heated. Box gets hot plus their is no air vent. Can cause a fire I may have to customize it my self. That'.s way i gave it a 3 star.
