    Pros: Really powerful for size and extremely power economic. I mean I run it from 18v 3A lithium battery from powertool, and it runs literally hours at really loud volume. I used a 6½" car speaker in enclosed cabinet and put the amp inside the cabinet also. The Aluminum warms only to lukewarm run... Read more

    Decent little amp - at first I tried it at 16V, and it distorted notably driving two 8 Ohm speakers at a reasonably loud volume, but then I switched to a 22V supply and it got a whole lot better, even at significantly higher output levels.

    Impression:Nice Amp;

    Great amplifier. I am using it with 12V/1A power supply and I got enough volume for my needs and I can play loud enough for my neighbours to hear it too. With higher volume there is some distortion but it is because I am using that poor power supply. Great and loud sound!
