yes it is dusty I know, I took this picture a year from installation. Here in this picture you can see a 600 watt pc power supply that was modified to run a 12 volt automotive amplifier. I took apart the power supply and combined all the rail voltages into a single output. I used the 12 volt rail for the automotive amplifier. I used the 5 volt rail for the Led drivers. I capped off the +3 volt rail and -3 volt rail. I then ran the outputs of the amplifier to a 10" sub and two 6x9 speakers.
