I have an '05 g35 coupe with factory bose audio. What is required to connect a new head unit such as an alpine w505 or a pioneer avic-z3 to the bose speaker system? I understand the system has a factory bose amp. Do these head units plug and play with the factory speaker setup? I don't need help with the dash reconfig to fit the head unit, but I do need help from someone who knows the bose speaker system and how it will react to a new aftermarket head unit.

 

bose amp will work fine just buy a 7550 harness, antenna adapter, and the dash kit. connect the blue/white from the deck's harness to 7550's blue wire and it'll work
