    Kemo 28-6402

    Overall: 3 out of 5

    I measured 3.4 Watts "RMS" into a 5 ohm load while monitoring with a scope and a padded down headphone. If driven any harder, it clips/distorts severely. It "takes-off" (oscillation) below 40 Hz. It is a decent utility amplifier and at the price, there is little reason to "home-brew" something for a quick project.

    4ohms vs. 8 ohms

    Overall: 4 out of 5

    Perhaps before dissing the amplifier you'd note that it is 12 watts peak at 4 ohms. That means 6 watts or less driving one 8 ohm speaker. You need to run two 8 ohms speakers in series for the amplifier to see an 4 ohm output.

    Good small amp

    Overall: 5 out of 5

    I got this amp to make a electronic game caller. I used a 6 volt battery to keep the weight down and it was plenty powerful enough to drive the 12w "Johnny Stewart" horn speaker that I was using. I hooked it up to 2 of the 6 volt batteries in series to see how loud it was and it was "killer" loud. For my application I couldn't ask for anything more.

    More like 2-3 watts for music

    Overall: 2 out of 5

    I bought 2 of these to make a small stereo amp thinking that 24 watts would be plenty for a small set of computer speakers. I made a housing for these to power 2 small computer speakers matched with a powered sub. These cannot reproduce music at 12 watts thats for sure. They distort terribly if any bass is present even at 250 Hz. Perhaps these are better suited for alarm signals where distortion isnt as audible.
