MA170 - NO PSU

This is a nice amplifier and has worked well since connecting it to my computer a few weeks ago. The sound is clean and the volume knob has nice LED lights which add to the environment when listening to music. It was simple to set up and has been simple to use.

Replaced an old DROK Micro Stereo Amplifier that I bought in 2017 that set in my garage and used hard and finally gave out. Used this as soon as I received it with in hour after being place on my doorstep. I resumed my old 12v 2 amp plug and a set of 6ohm Techicns book shelf speakers. It preformed without a hitch in our Texas 90 degree heat with no air flow on it for three days straight. It got warm to the touch but nothing to concerning and I was jamming it pretty loud. I do like the fact that I can adjust the bass and highs, and has great sound. I’m a huge SQ guy and this gets my approval. Hopefully I get 8 years out of it. May purchase their 2.1 later down the road but first need to upgrade my outdoor speakers. Really enjoying this amp and worth the 12 bucks.

This is a great little amplifier for under $10, and it works very well except for one minor annoyance that's easily fixed. I have a Kindle Fire hooked to some small speakers (through the headphone jack), and I use it to play rain sounds at night when I go to sleep. The problem is that even at full volume the output of the Kindle just isn't loud enough to hear the rain sounds very well. This little amplifier solved that problem- it's got more than enough power to play the sound as loud as I want. It's easy to hook up and works like a charm to boost the sound. THE ANNOYING FEATURE Several people have mentioned in their reviews that the amp contains a very bright LED behind the volume control, and when the amp is on it cycles through various colors. It's so bright that it would light up part of my room and the changing of the colors was also extremely annoying. If you're experiencing this problem (as others have mentioned in their reviews), there's an easy fix that you can do in about 5 minutes: 1) Unplug ALL the wires and connectors from the amp. 2) Pull the volume knob off (it just pulls straight off, no tools required). 3) Behind the volume knob is a clear plastic piece that's attached to the shaft of the volume control with a small flat nut. With a pair of pliers, gently unscrew and remove the nut. 4) Gently pull the clear plastic piece off. Behind it is the LED that is soooo annoying. 5) Take the clear plastic piece and spray paint the back side of it with some paint. Almost any color will do as long as it's not transparent. Give it a couple of good coats of paint and let it dry. 6) After it's dried, put the plastic piece back in, screw the nut back on, and press the volume control back on the shaft. That's it- problem solved. No more annoying light. :) (Alternatively you could follow the steps to #4 and then paint the LED with some nail polish or dark paint.) I hope this fix helps others. Aside from this one minor annoyance, this is a great amplifier for general use and I wholeheartedly recommend it.

I'm using this to replace my desktop speakers with some Klipsch RSX-5 speakers. The speakers are rated for 75 watts so I wasn't entirely sure this would power them sufficiently. It was actually plenty, with good speakers, this can fill a room with a good level of loudness. I was worried about the power draw so I dug up my watt meter and saw it was only using 2.6 watts!!!!!! (now I'm using 1.6 Watts MAX) At this point I was intrigued and I set it up to my two Polk Monitor60 Floorstanders (with 3 6" woofers and a tweeter in each, for a total of 8 speakers, Rated for 150/300 Watts) and it sounded acceptable (drawing like 4 watts), not as good as my $300 receiver, but at 3% the investment and virtually no heat or power use, it is a strong contender. Bass and Treble Boost works but is limited of course. I was going to set this up outside but got distracted and left it sitting on concrete in Florida sun for three hours, it got pretty hot. It still works, but now is makes the speakers make a weird noise when I turn it on (high-pitch low-decibel, not bad, just weird). It wasn't even on, or plugged in... Since it was $10, I don't blame the piece but want to share that experience. Ending statement - Great bargain at $10-12. Though it could power bigger speakers enough to use as a primary system, I wouldn't recommend it, but I will definitely never use a pair of "computer speakers" again, thanks to this. I'll probably buy 2 or 3 more of these for various rooms in my house... I powered my amplifier with a high quality 12v 2a Adapter I got for LED Strip Lighting.

This product worked great for over three years but then died suddenly. To me, personally that was worth the amount of money I paid for it. But it’s a shame that now it is just garbage to go in a landfill.

Muito bom

NICE MINI AMPLIFIER

suena muy potente para su tamaño exelente calidad de armado y sonido y te puede mover asta un stereo completo forzandolo pero si tiene bastante potencia mas de la que yo me imagine y sobre todo que con una bateria de 12V lo haces un sonido portatii

Don't waste your time or money on this junk. The one I received is being returned immediately for refund.

I purchased this for a mod of a Street Fighter II Arcade 1Up cabinet - adding a Raspberry Pi 3B+ - as it requires an amp for sound. It works great, although I was expecting it to have a 3.5mm plug (1/8th Headphone jack input) but it doesn’t. But that’s MY fault for not paying attention even though the Amazon listing had GREAT pix. It has RCA inputs. Luckily (and inexplicably!) I had an RCA to 3.5 mm cable lying around. But just know that going in. It has a decent sound (currently mono as I’m only using the one A1Up speaker) and a nice LED light that I’ll never see. It’s light weight and so far, no complaints! Works great!
