I've got a 2000 Jetta GLS with the Monsoon sound system, I kept everything and fed it through the empeg. I added another amp just for the empeg and the necessary parts to pass the Monsoon deck through the empeg. AM/FM, Tape, and my CD changer all work perfectly. Of course, without the empeg in the car, I can't use anything, but I never leave home without the empeg, so it's not a big deal. The sound quality is great, and I didn't lose any of the empeg's features.
