Nothing but static

Hey guys. '95 XJ6 VDP. The car is in great shape but, the sound system, not so much. Terrible static. PO thought it was speakers but I don’t agree. Even fading doesn’t make a difference. I thought antennae, but on tape, still static. CD changer seems dead to the world. No message or response when tape/cd button is pressed, no cartridge ejection either. Any ideas?

Pull the trunk lining out and look for the cd changer multi pin connector and amp connections. If it’s either unit I have replacements from my 97 X300

Thanks I’ll check it out.
