Hey guys new to the z family and installed my z1 today everything works except the sound. I have read up on other people's problem and others answer with the factory amp. I drive a Rsx type -s 05 and it has a factory bose system already in it. I have wired all the wires as done by the manual, do I need to do something with the amp in order to get sound or am I missing something with my wireing connection. Thank you guys for the forum
