I have a 6.5" Bazooka Tube that I am wanting to mount in my 02 GTP. From what Ive been reading you need to hook up a GMOS -01 to keep door chime and ONSTAR (dont need that since they use digital not analog anymore), you also need a Metra ASWC to be able to keep your wheel volume controls, and you need a PAC harness since my GTP has bose stereo and onstar... But how the hell do you hook them up together??? Should I just get a dealer to hook it up for me? I just cant figure out (without a picture) how to wire up those 3 things all together..
