what you need is something like the Sony XA-39a. This is a small box with power, ground, and inputs for remote triggers to both head units, along with RCA inputs for F/R of both units and F/R RCA outs to amplifiers or crossover processors. It's not a real cheap device, but it works as a switching network so you don't get any feedback when using two head units in one system. It was fairly popular when we used to install cassette and CD heads in a car back in the 90s.. not so useful these days since a lot of head units have an AUX line input and generally handle everything most people want.
