I tried to tug mine off in the car last night
Misses went mad when she caught me.
Oops, guess I should reword that. I tried to remove the speaker grills last night. They seem to want to come off but I fear they may snap off before coming off nicely.
I'd remove the door trim, they're simple enough to remove. I reckon you'll find a 5 inch driver behind there, don't quote me on that but the grills look like they could hide such a beast.
I bet LR Guy would know the answers to this. He's my hero
