ok so does anyone know where i can find the adapters for the rest of the HU install on this car. i hear its like $150 and its just for all the data and the chimes and what not

also with the factory speakers (9 of them) how would i hook up the HU and have the factory amp power the speakers rather than the HU?

Do you have onstar or bose? If you have onstar and it is active you can use the PAC OS-2, if you have both you can use the PAC OS-2BOSE. If you have neither you can use the PAC C2R-GM24. These will allow factory amp integration. Any reputable shop should have these parts in stock. They run between $120-$170.
