i am going to be putting a carputer into my jeep for the purpose of navigation, mp3's, movies, and live tv. the question i have is what should i do for power, i have search this for a while and found i could use a power inverter, and a regular power supply (noisy and not the best but i would have spare 110v ac power plug :-) for stuff like drills and drop lights), or the other option is to use a dc-dc converter like the pw 200 m but would i have to run a voltage regulator, any ideas or links will be greatly appreciated
i have searched and i just wanna know which way is better to go about this i will be running a p3 @ 1ghz and a hard drive,i just don't want the noise from the power supply and the power inverter
