Fastback rear speaker boxes

Suppliers out there for the Bluetooth installed inside a vintage radio I believe.
Stay AWAY from Retrosound. I will be putting the head unit and amp under pass side seat. Factory am/FM stays put in dash. I have 2 round 3.5" or 4" in dash. Installed in factory spot but used an adapter plate a fabo member makes/sells here.
Yeah, I guess. I have a hole in the dash for a radio I need also. I saw a thread on here where a guy was putting bluetooth stuff in a factory AM . If I was smart enough I would like to do that
Any one else having issues with retrosound radios in their mopar?
