After a good read about the
Corvette Pace Car setup I've decide to use the
Maya EX5 to get the sound from the computer to the amp, as well as
WinFast 2000 XP FM for the TV/Radio.
Also, there's a lot to be said for using a laptop. For one, you can get a powerful machine with a broken screen for dirt cheap compared to the price of one with a working screen. Also, running off battery power would be nice since I have a tendency to listen to music while the car is turned off.
