    This packs a punch for such a small amplifier. Put to about half power my sealed 12 inch subwoofer was shaking the house with this little thing. I have ran this thing pretty hard for hours to days at a time and the heat sink is still cool to the touch. Very efficient and effective little machine. Highly recommend

    This amp was needed, as my subwoofer amp died, and I was not ready to give up on it. It was easy to replace inside the subwoofer's housing. One caveat: the line in needs a powered input - from a headphone jack or similar, not from a variable volume line-in like most powered amps would use these days. Not to worry, tho, you can power it from the speakers output (B speakers, for example), and adjust the volume on the amplifier.

    I used this as a replacement amp in an older powered sub. I heavily modified it, but it seems to work just fine. Beats buying a whole new sub woofer.
