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).

I installed this in my 1954 Chevy truck. It fits behind the dash, with the on/off and volume knob located in the original place for the radio knob. Works well on 6 Volts; one wire (fused) goes to my accessory circuit, the black wire goes to ground. Two wires then go from this unit to a speaker, which was also fastened to the original location for the radio speaker. Draws very little current; the ammeter does not even move when the unit is turned on. Installed a radio faceplate and original style radio control knob, and from the outside the unit is indistinguishable from an original radio.

The ammount of power these little amps put out is amazing. Built job site speakers using them and old drill boxes and speakers they're loud and cheap

The sound quality is alright. (Not great; there's hiss at full volume; heavy bass is distorted; but at low volumes it's kind of OK.)But I found a huge bug in its functionality.When no audio is sent for several seconds, the thing apparently enters some kind of sleep mode. When audio is then sent to the device while sleeping, it does not instantly wake up, but only wakes up after about a second. That means there is a gap during which audio is not played at all.So if you connect this amplifier to a computer that makes a tone for incoming messages or notifications, and the tone is only ~1 second long, the amplifier will not play the notifications! The amp sleeps through the notifications!This is a disaster rendering the device useless when receiving notifications is important.If you just want to play music, I guess it's not horrible, but you still will miss the first second of the music sometimes.I give one star, since at any price I just can't use this. I guess I'll try to return it.

First off, as you probably guessed, this is no where near 50w per channel. With a 12v power supply and 8ohm speakers, I measured a tad over 4w. With that being said, for the size and price, this little amp is decent. The bluetooth only goes about 15 feet line of sight, but the fact that it even has bluetooth for this price negates the short range. It connects quickly and plays clear when your phone is close. 4w sounds low, but it will power a pair of bookshelf speakers just fine. The bass is really flat, but that's also expected from such a small chip with no dynamic headroom. This amp is perfect for small projects needing cheap sound. I have it running a pair of JBL bookshelf speakers on the patio and it does a good enough job. Just don;t expect 50w and you'll be fine.

Very large sound from a small board. Almost lossless distortion. I had another set up on the bench for an mini in-dash BT/FM/Aux receiver/amplifier, so I just needed to swap in the speaker leads and the power supply. Used my variable voltage supply at 12V-2A. Connected to a pair of 3" full range (60-20k), 90 db sensitivity, 4 ohm speakers, 40W (specs call for 50-100W input). No noise issues at all (others that reported this likely misconnected the amp/speakers). Bluetooth sourced from my Fire tablet, found the device in seconds. Volume set on max on tablet, then tried various volume levels on the amp, including full out on Classic Metal on Slacker (I know, LiveXLive), no distortion discernable. Speaker specs recommend a passive radiator for improved bass, this was just a free air test. Played on Piano Jazz on Slacker, awesome sound.I really like the switched pot they used for volume - simply on-off and volume operation. Only thing I saw on initial test was the volume seemed to go out well before Off position, likely due to the pot value used, I'd give it a 4.5 for that....otherwise a 5 overall. I have a few 24V power and torroidal transformaers I may try for a permanent power source. This may end up a desktop or portable bluetooth speaker
