OK..I did research a lot of times and I guess maybe I'm not putting in right search words cause I cannot find it at all..

Anyway..I bought AVIC-Z1 to install in my 06' coupe w/ BOSE..Here is my question..I already got DD dash and AC controller..AndI know I need Metra 70-7551..Which part do I need for the Antenna?? And is that all I need?? I read about converter for using stock amp..Cause I am using stock amp and stock speakers. Which converter do I need? And where can I find them? Thanks
