You can drive the Bose speakers with an aftermarket head unit, BTDT.  
The easiest head unit to install is Blaupunkt, inasmuch as the  
connectors are plug and play with the Audi harness, just two pins to  
move in the power connector. With a little rewiring at the Bose amps  
you can use the Audi harness wiring to the speakers.
