I'll take pics when I go home, the inside is virutally empty, there is just the power supply, which we swap out, the front pannel, which is most of the space, the rear pannel, and a small board for processing inside. You only need 3 of these 4, 2 of the 3 connects useing a ribbon cable, and the only other connection uses wires for power. Totally downsizeable.

On the downside, my amp is messed up http://www.mp3car.com/vbulletin/car-...300-4-amp.html

edit: You could also relocate the front panel to a more convienient spot... but it would be tricky splitting the panel up
