I had an Alpine rear entertainment system installed in my 08 Escalade with factory NAV HU. The problem that I am having is that the volume through the included Alpine FM modulator is extremely low and the volume on the HU needs to be turned way up to hear the movie through the car speakers. Any ideas? Is this common when installing aftermarket systems because of the Bose system? Should we try eliminating the FM modulator and run RCA's from the Alpine unit into an aftermarkey AUX device?
