Step 2Power Supply
Between the speakers I glued some wooden pieces to carry the amplifier, but more to that later. As a power supply I used a computer supply. Well I tried one before but it was too weak. Because the amplifier need some 10A on 12Volt I had to get a stronger on.
The powersupply finally used has 300 Watts and pumpes out 15 A on 12 Volt which should give me enough flexibility. Further than that I desoldered a lot of the cables I didn't need. I only need 2 yellow (12Volt) cables, one red ( 5Volt) cable, the green (on/off) and 4 black (ground) cable. It sits at the bottom of the whole case. I turned the airflow the other way (flipping the fan), so it sucks in air through the old bottom connector bracket, which I widened to get onough airflow.
To get the power supply going you have to attach the green cable to a black cable. But often the Powersupply checks if it has a load and will shut off if it notices that there isn't any. So I joined a 5Ohm resistor to the 5Volt cable and a black cable, and the power supply keeps on running. But the resistor get's quite hot so it is joined to the fan outlet to cool it with air. Be extremely carefull when handeling an opened power supply, always disconnect the power cord.
In the corners of the case I glued 4 threaded rods to hold the top piece later on.
