Youre best bet is to either buy a pair of speaker pods off a VR/S and mount them on the doors. Either that or buy a pair of Aerpro speaker pods, see below:
Speakers And Spacers - AERPRO Car Audio Accessories
The APF60CF, APF60BL or APF60GR would suit you if you dont have splits (component) speakers.
Both options will require you to cut holes in the door interiors to allow for the speaker pod (VR/S ones) to be mounted or for the magent/wiring to go through (Aerpro pods).
Only problem i can think of is the colour of your interior, if im not mistaken your interior is a tan colour? The VR/S pods will be light grey and the Aepro (as you can see in the link) are available in either black, light grey or carbon fibre.
