I am getting ready to do my upgrade of the existing factory 9 speaker system. I am keeping the existing head unit and replacing everything after that. I know there is an excellent writeup using the A2B interface ( Red Rocket’s Full S650 Mustang Stereo Project (9 Speakers) | Mustang7G - 2024+ S650 Mustang Forum (Dark Horse, GT, EcoBoost, GT500, GT350, Mach 1) ), but I am wondering if it's possible using just the idatalink/Rockford Fosgate DSR1. I believe the iDatalink HRN-AR-FO3 Harness should plug in directly to the factory amp inputs, but I would be missing the center and tweeter signals. So a couple of questions about this:
1 - Is the input signal pure in the sense that it is full range? I know you need to flash to remove Active Noise Control
2 - Assuming I disconnect the center and tweeters, will I lose door chime and BT phone call functions since I heard both only go through the center speaker?
