Review: Don't expect much with all the positive reviews...you need to have good quality speakers and it can't pull 80w speakers also...as someone mentioned.... False marketing specs... Quality will be good with good dac and pre amp ...Ideal for 30w-40w speakers and 50 w subwoofer... Don't expect punchy bass .. for this price range it was a good one...I am using 18v 20A power supply.
Review: This thing slaps, its great at 2 ohms at 80w rms but it does get really hot so add a fan or bigger heatsink. Also it is NOT bridged at the subwoofer output, it is only one channel and other 2 for mids, 3rd one is left unconnected. Im not sure why the left the 3rd channel unused, theres no traces going to it at all. It would have been better to have dual sub outputs to run 2 subs instead. The sound is also really good and it outputs full range and lowpass

### ⭐⭐⭐⭐⭐ Review
*by M***S on 24 October 2025*

I bought this since it's 2.1 output and importantly class AB. I just wanted to hear class AB over a little D amp I've been using for a while. Sounds nice and I think I can hear the warmness vs D! But aside from that, some important things to note and observations from other reviews. It'll play with as little as 9v and up to 18.9v. As soon as it gets 19v it cuts off output to the speakers. I don't know how accurate my little Ali adapter is with actual voltage, but the number 18.9 is the most it will take and play. So unfortunately, a typical laptop 19.5v adapter you've got won't work here (I tried), but at least it won't blow it up outright. Also output wattage is good, I have a mix of 4 and 8 ohm speakers that work well. I suspect the max power rating of 80x2 and 120w sub is only if you are driving 2 ohm speakers as stated it can do in the specs, which the other reviews complaining about output haven't mentioned what they are using. Edit: From the ST datasheet for the TDA7850 chip: ■ High output power capability: – 4 x 50 W/4  max. – 4 x 30 W/4  @ 14.4 V, 1 kHz, 10 % – 4 x 80 W/2  max. – 4 x 55 W/2  @ 14.4V, 1 kHz, 10 % So try testing 2ohm speaker at 18-19v and lots of current if needing to hit the max.
