What do you mean? You mean if you run the sound from the sound card to the amp right? It shouldn't be a problem. Some people talk about losing power by splitting the signal when running the sound card in regular stereo mode to a 4 channel amp.
If you want full 5.1 sound though you'll probably need two amps (one for the front/back speakers and one for the sub). If you don't have a center channel you can lose the sound for voices when watching a movie, but this isn't a function of the amp.
Since you're car isn't a theater, many have said to avoid the 5.1 all together. When running in 5.1 mode (for the Epia board at least) you can't use the line in so you'll not be able to use a non-USB tuner card if you want that as part of your system.
