Review: Good value - I powered this with a 19V power supply from an old laptop. I attached speakers and a subwoofer from an old TV audio receiver and it works great. Given that I used 6 ohm speakers and 19V power, the theoretical maximum power would be 60 watts. I'm able to get nice clean noise-free audio at that power level. The separate volume controls for speakers and subwoofer allowed me to get a good transition from bass to treble. A minor complaint is that there is a loud pop when the unit is powered up or down.
Review: Good amp, clear audio, low power 15watt? x2 + 26watt x1 - I did not check the power output of the stereo (highs/treble) side, but I did test the subwoofer/bass side of this and all I could get out of it was 26watts. So 1/4 of what it says, so I'd assume the same for the stereo/highs/treble side of the amp, so that is probably around 15x2. 18-20VDC seems to be the sweet spot for power. Any higher and this amp gets very hot (233F w/24VDC). The bass side of the amp is weak. You turn bass knob up, treble down, and the highs will still over power the bass. Maybe need to use a lower power subwoofer. I tested with a 12" 4ohm 100watt rms sub (it is good quality, just not enough power) also tested with 8" 8ohm, 6.5" 6ohm, 5" DVC 4ohm each coil, and a tiny 4" subwoofer part of a samsung bluetooth bar. The 12" sounded the best. I did also test with another 12" 4ohm 400watt rms and I barely heard it. Also note the knobs are not a frequency control, all 3 are volumes, treble volume, bass volume, and overall volume. Overall this is pretty good amp, just needs a little more power on the subwoofer side.
