Hello, does anyone know the size of the speakers in the rear door cars on a 2014 model? One of mine has blown and I want to replace them with after markets, thanks

16,5 cm or 6,5"

For example a "Audison Prima APX6.5" coaxial is a complete set.
Speakers.
Speaker rings.
Adaptor cable's.
All Plug & Play.

In fact the rear speakers are somewhat smaller - the fronts are as per Hans' answer above, but the rears are approximately a 5" unit, although the mounting space is very limited. As a result I bought these 4" units ;

... and they fitted well. Needed some appropriate spacer mounts, so I got these too, which fitted a treat;
