This is sort of a wiring diagram or pinout question..
With oem amplified or "premium" systems such as my 08 Si Sedan, has anyone tried taking a regular harness that would be typically used for aftermarket head unit, and a reverse harness which goes into the head unit, and combine them with the balanced line signals out to RCA to feed amps/processor?
Might be a simple way for a plug-in bypass at the front-end head unit which could be easily reversed simply by unplugging the custom harness out of the chain.
Ok.. playing around in visio.. something like this???

.... All assuming of course I have the pinouts correct, which I probably don't. duh
