How can I replace the built in radio amplifier? My speakers pop with no sound, but my radio in the back works with head phones.
My wife has an 04 yukon with the bose sound and the factory dvd player. I have heard that some stereo shops have used the gmos-04 harness adapter and an aftermarket radio with a custom made harness to keep the dvd player functional. I have a sony gt-740ui player in my car and would want to use this model in my wifes ride also if possible. Im basically trying to put some subs in her ride and have tried all types of line converters tapped into the factory speaker wires and I guess it dosent put out enough signal for the amp to pick up. If you know another way Id appreciate your opinion. Thanks.
