MakerHawk Mini Amplifier Board Bluetooth Amplifier 2.0 2X50W 5V-24V Audio Power Amplifier Module for Store Home Theater Speakers

It's works great!

Works as advertised and very simple to set up. When I had questions, they replied very quickly.

I would have never guessed such a small little AMP could put out so much power and still sound great. I am using it to drive 2 Klipsch 8” bookshelf speakers and there is plenty of clean crisp sound thats just as good as my high end Denon amplifier.It is very small (about 2x2x3/4”) and simple. Power and 2 sets speaker leads out. Power button with a little blue LED tells you its on and a 1.5” volume wheel on top. Quickly and easily connected to my phone via Bluetooth 5.2 and I could not hear any perceptible lag or signal dropout. I also own the non Bluetooth Aux/USB input version of this little amp and I am extremely pleased with bothIt does get a bit hot after a few minutes if you drive it hard bit not so much to be a fire hazard.It is important to choose a good power supply. Its spec states it will work with anything from 12V 1A up to 24V 5A which is what I am using and is probably overkill for my situation. The higher the volt/amp rating the louder/bigger speakers it will drive and still sound good, but like many situations the law of diminishing returns applies as much here as it does in most circumstances. Im sure if I experimented I could finder a lower rated power supply to drive my speakers and it wouldn't run as hot.

This was used in many quick DIY Bluetooth speaker projects. All of which were given to a homeless community where they were put to the ultimate test. The bluetooth unit came back several times because it wasn't working. Not a single time was it the bluetooth unit itself. Always a connection or power supply failure. The pics are the latest glued together model that works like a charm. This thing was pulled out of a river at one point. I've had bigger units with more bells and whistles that were damaged, some beyond repair but this guy was bullet proof for me. I will buy again. The Bluetooth speakers are much more presentable when first put together so I apologize for the crude look. You can't go wrong with this unit at this price.

I have it hooked up to 2 4” speakers from a boss audio motorcycle kit that I didn’t have an amp for. The Bluetooth pairs within 3 seconds of it being powered on and the volume is so loud that it hurts my ears at full tilt. It is pretty fragile as it’s a small electrical board but I’m going to make a waterproof enclosure for it. There is zero distortion and I’m only using 15 volts at 1.5 amps. The fancy motorcycle amps usually cost around $80 and don’t sound this good.

i like to return by ups pickup 2times i bought broke? again i need to return this bought twice broke 1day junk

Currently using with a 12V, 40A, 100% duty cycle power supply to drive some 6 ohm bookshelf speakers.If the specs are to be believed, this little board is supposed to be able to pump out 12W per channel at 12V with 8 ohm speakers so, my best estimate is that it should be able to provide about 15W per channel in my configuration.To be honest, I'm not sure I'm getting that kind of volume but, other than that, this thing is great.Sound fidelity is amazing for what this is. The BT connection tone is pleasant and not overly loud. Connectivity is good and I absolutely love the analog style volume control with off switch. The noise to signal ratio is really good (no hissing or popping).

This little unit works great for in my vintage restored drive in speakers.
