This device turns the MOST optical bus output into a low level line ready for the input to car amps, apparently these can be used with or without the factory amp or set up as a Bose Amp in the VCD software.
I can only seem to get from France (took me a while)

Unless anyone know of a UK supplier.
The idea is to fit a 4x 75w Rms Kenwood amp from my last install and fit the Mac Audio components instead of all the factory fits, and disconnecting the mid speakers.
Then eventually a Sub which will be fed from a separate amp from the line output in the kenwood
