I have a few questions for everyone on here. First i want to replace my headunit with Alpine ixa-w404, Change the speakers to Focal 165VR components front, focal 165CV for the rear. i was looking to use the following adapters, GMAH24, and the steering wheel retention kit.

Anyone use any of this yet?

Questions

1.) Replacing the headunit and speakers can i retain chimes?
2.) If i run new speaker wire to each speaker, can i retain factory chimes?
3.) What about onstar?
4.) Do i need to mount a small speaker somewhere for the chimes and/or onstar??


I forgot to mention i have a 2005 Grand Prix GXP with monsoon.
Thanks for everyones help
