My preamp has two outputs for each channel, so in my case, I just connect one to the mains and the other to the subs. But it can just as easily be done with a Y-splitter. Go from the source to the preamp and from there to the sub crossover and to the mains. You'll want a volume control between the source and the amps, because that will control both mains and sub volume. That's really the only reason I use a preamp/buffer - I need something with a volume control. It's nice to have a switcher and wireless remote too.
