Well I installed the X-BOX in my car (executor 2.2 lite w/ Maxtor 160gig), powered by an invertor to a 7" indahs screen..
I haven't completed my install, but i just got back from a 4 hour road trip.. Despite the bumps and jumps, and my 2 12" Infinity Perfect subs pounding, the X-BOX did not even break a sweat, nor did it shutdown..
I am impressed... its useful ness is totally unheard of as an IN-CAR multimedia system.
Now.. Aside from finding a powersupply that will not shut down when i restart, I think i will buy another x-box to permanently mount (hidden) outside of the original casing inside my car... and hook up a removable harddrive bay so i can use the same harddrive in the house. That why i can clean up all the wires.
