Step 1: Case preparation
I cut out a 12mm board to house the speekers ( 100mm max 120Watt) and they sit pretty close together but that is necessary, because it is going to be pretty grammed in there. I did cut off some of the the fake leather to make the glue stick better for the board. Glued in the board stiffens the whole case.
Step 2: Power Supply
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.
Step 3: Amplifier
I will be able to adjust the vol/treble/bass seperate for the two channels in case I only take one subwoofer with me. Installed in the case everything fits just perfect, but it's getting already pretty crammed in there.
Step 4: LED sign.
To achive this it was eather using some 120 leds or doing some fibre optics which I could get my hands on. So it was down to the fibre optics. I drilled the holes, a lot ot fhem. Glued in the optics with hotglue (let it cool down a bit on the tip of the hotgluegun, or it will melt your fibre optics) and bundeled them to be lid by 5 leds. I made a special bracket to hold the leds in place.
Step 5: Finishing touches
Well and thatÃ?ÃÂ´s it. Took me about 4 Month to finish it all together. Hope to give you some inspiration for your projects. Some more stuff on my side, that still needs documentation:
