This is essentially a Car PC forum, though most of us DO have our carpc's connected to a car audio system of some sort. So, if you're looking for car audio forums (without necessarily the carpc):
There are more...just check the car audio forum here. There is a sicky at top that's titled "have car audio specific questions?"
But, if you're planning a carpc install, let me say:
>You can rip ALL of your cd's to carpc at very high quality
>Carpc sound output cards can produce exceptional sound results
>It's easy to see album art and play music using carpc touchscreen
Plus, a carpc can have GPS, cameras, ca diagnostic monitoring (OBDII), fm, satellite, etc radio, bluetooth phone functions, etc, etc, etc
It is suggested that a new person take some time to carefuly read a LOT of posts, tedious tho it may be,.
Check out my pictures and you'll see something of what this carpc enthusiast has done.
