Hi guys, sound is not my strong side, so I'm kinda lost in here. Right now my carpc is hooked up to the sound system thru HU->Aux Input. I'm planning on loosing HU and use carpc thru amp. But here is a question I cannot understand. If I use onboard 2 ch sound card hooked up to a 5 channel amp (4 speakers + sub), will it give me 5 channel sound or not?

Thanks in advance.
