Hi there. I have been after getting some new speakers for my car for some time, but have never been sure of the size. Can anyone tell me what speaker sizes drop in as standard into my car? I think its 4" on the dash, and 5"1/2 on the back panels, but I'm not sure. Also regarding fitting, if I take the current speaker grills off do I then have access to the speaker? Or would I have to take the dashboard apart etc.. Thanks for any help.
