I would like to fit some rear "fill Speakers" in the tailgate door of my Move/Kenari and was wondering if I can fit one of the following sizes.

9 x 7, 7 x 5 or 5 x 4 elliptical.

As the door depth is quite restricted and the boot completely full of my day to day gear I need a speaker that is low profile on both sides of it's mounting plate.

Can anyone advise the best size/depth compromise. I have already replaced the front speakers and fitted a slim powered sub under the front passenger seat.

TIA
