I'm not sure what u mean but the way most people do it is by connecting the soundcard in the PC with the different amps, most soundcards have options for running Stereo/2.1/4.1/6.1/7.1 etc. the .1 is the subs just to be real clear!
your setup seems to be a 2.1 since u dont want the tweeters and front door speakers to be on different sound channels, just get 2 3.5mm->RCA cables and a pair of RCA splitters.
Then check the manual for the soundcard what to connect where. the splitters is to get your front speakers and tweeters to the same channel.
