This is an amplifier for my subwoofer and is part of my 5.1ch audio system connected to my PC.
The enclosure is completely self-made. The frame is made of wood and the front panel is alloy. It has only a ultra bright white led and a volume adjustment pot. The plexi-glass is covering the whole thing.
The cooling for two power transistors (epitaxially connected darlingons) is done by an AMD Sempron's heatsink cutted in two pieces. There is also a manually adjusted fan (3-12VDC)(The transducer is in the lower right corner on the picture) So far this system has worked perfect.
The amplifier has a 120hz/12dB crossover. (on the picture upper right corner).
On the upper left corner is the toroid transducer for the amplifier itself.
