I have a 08 STS, how can I retain the chimes once aftermarket amps are installed?
The GMOS-13 is being shipped from metra, once here I will install my pioneer avic-z130. Soon after, I will be replacing the stock speakers with aftermarket ones, along with an aftermarket amp. Metra's tech support told me that doing this I will lose my chimes. They also stated that I could zip tie the factory speaker under the dash, to retain my chimes. Has anyone had success in doing this? Please let me know, as I would like to keep my chimes intact. Please let me know the steps that were taken in this process.
