OEM Sub and rear door speakers loom

[WelshWoody83]

Hi there, I was wondering if anybody knows if the wiring loom for the rear door speakers and OEM sub would be in place on an A3 sportback 2008 model if they werent installed at the factory?

My car doesnt have rear speakers or the sub and I was wanting to try and install the OEM parts.

Any advice would be greatly appreciated!

Thanks in advance

Chris
