(cont from last pic) e) inverter partially hidden under felt f) relay to turn on computer power g) amp fuse h) trash I should'a picked up before taking this picture. Oh yeah that's a Pioneer 4 channel amp 50x2 and 120x1 bridged. One suggestion is a DC-DC power supply for the computer instead of what I used. My mp3 player was darned close to free because as a computer instructor, I only had to buy the X10 mouse remote and the inverter...the rest I had lying around! ;-)
