What's a Riverhead lighter? In case you're asking about the rear speakers in the headliner (gotta love auto-correct), they pry off. It helps to have a good trim removal tool when working on interiors, and is worth the money even for occasional interior work.I was thinking of doing the same thing with a real headliner speakers. But I can’t seem to pry grills off the Riverhead lighter. Any suggestions on how to do that? At least without causing any damage. I have a limited with the HK system.
