Need to replace the mach 460 6 disk CD player in my 03 cobra and keep finding different information on weather or not it will sound and work correctly. I just want to replace the head unit and have found info saying it wont work since something was changed with the amp control and the factory head unit in the 03 and up mustangs with 6 disk in dash units. Has anyone had any luck with just replacing the factory 6 disk unit with an aftermarket cd player? Also anyone know what extra wiring harness i need to get to make it sound better? Thanks for any help offered.
