basic laptop installation

Hey, new to pc/car installs, experienced stereo installer..Basically i have like 3 laptop pc's roughly 3 years old, but extremely small and somewhat powerful. the best of the three is a Ricoh NP-70, which is tiny and loaded with features, like infrared, and an ES1879 plug and play audio drive????...what do i do? what do i need? and where do i get it?....basically i just want to load and play mp3's and/or maybe add an external dvd player...should i integrate it into the car, or leave it whole also?...THANK YOU any info WILL help!

You will either need a Power inverter to plug the lap top in, or a muti-volt adapter, find a voltage that will work for teh cig lighter, then hardwre it. You can use a Casette adapter, from the Audio out port on the Laptop, to the casette adapter and that will play when you have a tape in. You can put the laptop anywhere really, mount it like the police do. I have already done this once, but I bought a CD player with MP3 playback, and put all my Favorites on that. The laptop thing works, you can download a player. Make sure your AUDIO SETTINGS on teh laptop for windows is set at the BEST possible sound/sample conversion. There is a setting: START > SETTINGS > CONTROL PANEL >> MULTIMEDIA > ADVANCED PROPERTIES > PERFORMANCE, and choose BEST for both settings. If you do not have that, there should be a setting for the Audio wuality, and it should be set at CD Quality. The default is like RADIO quality. . . If you adapter suppostr 3D Quality Environment, try that too and see what you get. You can wire the LAPTIOP into an AUX input port if your head unit has one. Wiring right to the AMP, you would need to asjust the volume ON the laptop with the Volume in the systray. . . In SHORT, it will work just fine if done right.

THANX POWERSLAVE, So basically, All I need is power, and sound...i.e....RCA's?...so the headphone...aka-mini-plug out of the Laptop into an RCA into my AUX input on my head unit...?..without a "digital to analog sound convertor"...someone told me about?...i wouldnt think i would need that?...any help
