If I understand your new system, when the empeg is out the CD player drives the amps through the switch, otherwise the cd goes through the empeg to the amps. If so, that sounds a very neat solution, although you'll have to be careful when removing the empeg from the car.

You'll need the CD player at high volume when playing through the empeg. If the empeg is removed, the CD player takes over, and you get instant full volume... =)

I did this by accident when tracing a ground loop and it hurt (I normally run the empeg into my MD/CD, but I took it out of the system for a few minutes to "debug" some noise).
