Are there any solutions out there that would give me a true multi-channel solution? I want to build carputer and one of the components I have selected is a USB Audigy 2NX, which can do up to 7.1 audio, although I will be happy if I can get 4 discreet channels. So far everything I have seen is nothing but stero expanded to the front and rear. I have asked this question at several Best Buy stores and the guys look at me like I am some kind of alien.

Any help would be appreicated.

 

got a feeling this will reqire alot of rigging. surround sound files are really only available on dvd audio or higher plateau media. i work for a production company and we do some surrond mixing. i think you may have to use a theatre sytem to out put tru multi channel. if there is a deck that can handle this, ive never heard of it,

 

I did some quick research and it looks like this has been attempted before and their may be some chance you can get it done. but this is a region of technology that won't really be easily avail in cars for a few more years

 

I just put a Rockford Dolby surround processor in my box along with 6 speakers, 2 tweeters and a sub under the seat.
Dash & rear speakers are the rear channel, doors are front channel. Had no use for the center channel. Decodes FM and CD's nicely. Channel seperation is awesome.

There are a handful of surround sound processors.... most will be a 5.1 configuration for the car though...

I love DTS...

 

OMAC, I'm designing the same project as yours, Carputer and surround sound. Here is what my plans are:
MB899 mobo which has an optical output (any other mobo with output will do fine), Alpine pxa-h600 digital processor and 2 alpine PDX-4.100 amps. The amps are selected because they run cold and can be stacked under the chair.
The pxa-h600 can be found for around $200 as opposed $700 for the pxa-h700/701.
The optical sound from the mobo goes straight into the pxa which allows a lot of tuning in 5.1 with real or simulated center speaker.
For true 7.1 surround sound the Auzen X-meridian 7.1 card will work fine but it will need a powerful processor. With a slow CPU you can use the usb cards.
