What does actually the fiber optic do? transport sound, data? does MOST run through it? Does it mean I have an sound amplifier somewhere else in the car?
MOST is a high throughput media bus, distributed over fiber optics and set up as a ring in the car (if you disconnect one MOST connector anywhere, you break the ring, which is the reason for needing to mess around with the distribution block). The Logic7 amp uses MOST for input (it has DACs onboard for audio output), the combox/MULF connect to the head unit via MOST, etc etc.
