Building a portable system

I need to build a system totally portable, the only thing hard wired to the vehicle would be the power straight from the battery, with a quick connect / disconnect, and a ground. I cant use or alter the existing system or anything else for that matter on the vehicle, It's not mine. I am a long haul (Company } truck driver and I am issued a truck to use. The system has to be easley and quickly unhooked and stashed.  The system will inclued , a head unit, a CD changer, a XM reciver, a 4 channel 500 watt kenwood amp, a two channel 600 watt Bazooka amp, 2 enclosed 12 in. sub's, and 4  5 1/4 polk audio's which I put into boxes.  Is this possable or crazy.  If possable can I use 1 main power wire direct from the battery and split it to the amps , and the head unit ect.... Also can I use one 1 ground with everything going to it ?  One more thing can I put the head unit, Cd changer, and xm on top of each other and touching in a box or will the head get too hot ? Thanks

This is an interesting one, to say the least.  You must tell me why you have to take it out so fast! I am amused 

Amps do NOT like to sit freely in vehicles, it is detremental to their health.

build a mdf housing with carpet for your headunit, changer and xm reciever. Build a mdf amp rack too

This sounds like it won't work in reality though...

I need to dismantle quickly should I get called in to the shop.

I've built a carpeted stand for the amps giving them lots of room to breath yet not allowing them to move. Whats a mdf housing?

 I was going to build something to mount them any way ,some sort of box just concerned about over heating, being so close.
