Here is the thought, compact PC setup in my 1997 C2500. I can build one easily that will require little power and run off an inverter. Drive an amp with the PC soundcard output. Which will power the 4 speakers in my truck. Reason? Every CD I own is on my computer, plus about 500 more... plus random stupid songs like "Tone Loc - Funky Cold Medina", no way I care to buy the CD for that one or waste a CD burning it. Why not have ALL of my songs in one easy to reach place? I was looking and think I could mount a 9" LCD screen in place of the factory head unit and heater controls(relocate those down to the spot where the retarded pocket that just holds change is). Throw a trackball on the seat and a keyboard in the center console(or split bench I want to get). Anyone have thoughts on this setup? Biggest issue is I do not know what sort of power the sound card outputs. The speakers I have in my room have their own power supply but plenty of speakers do not have any power source other then the sound card.
