I'm attempting the impossible - to fit new rear speakers to my VW Polo 3 door. I've got the grills off, but the hole behind the grill is approximately 130mm diameter - much smaller than the 165mm diameter speaker I'm trying to get out (and the new one I'm trying to get in, so bending the speaker is not an option)

So it looks as if I'm going to have to remove the back panels - easy, you say, except in the new VW interior look, the panel goes all the way from the front of the B pillar into the boot! And there's no visible screws.

Has anyone got any ideas as to how I even *begin* to get the speakers changed, without taking it to a professional installer?

Many thanks,

A.
