I would like to fit 6x9 speakers to the rear shelf of my W124 saloon without damaging the original trim. I have done this before on a 190E by just cutting slats to bend away the metal work to create a good fit. The W124 only has teh space between the head rest 'cup' and the original speaker mounting. I would like to hear from or see pictures if anyone has done this before before I start taking the car apart to find out it can't be done. Much Appreciated
