5-door: Wires available for rearspeakers?

[Skeletor]

Hey guys,

I am looking into upgrading my car stereo, as well as my front Speakers.
Along the way I had the idea to fill the speaker-spaces in the reardoors, since they are empty as of now.

Considering they have made space for Speakers, is it possible that they've provided the car with matching wires already?
I'm asking as I am not going to order 4 Speakers without knowing - and I was wondering if any of you guys might know so that I don't need to remov ethe entire doorpanel just to find out and put it all back together, having nothing done on the inside.

Thanks a bunch in advance!
Cheers
