tC entertainment install

Hey all, need some advice. Here is the plan. I'm going to install 2 vizualogic headrest monitors in my tC. I also have 2 xboxs (modded w/ 140 gb hdd & mod chips) that I want to connect and run a crossover between for a system link. These are also going to be used as the dvd players. The things that I'm uneasy about are running power inverters for each of the xboxs, and I'm not sure what to do about a FM modulator. First off, can I still use the headphones with the monitor without connecting the modulator to one of the monitors, & what is the best way to connect the inverters. I don't want to plug into my cigarette lighters, I want there to be as few wires as possible. If anyone has any suggestions I'd really appreciate it. I'm sorry if something similar has been posted, but I'm really looking for some info. Thanks so much.

Why not use 1 larger inverter to power both xbox's rather than 2 seperate ones. That will cut down on wiring. To figure out the ideal way to wire the monitors up it would be best to know what kind of audio/video inputs/outputs each monitor has. Mike
