AUDI RS6 C5 RNSE conversion and looms

[Greegsy]

As above - recently removed from my RS6 Avant as now fitted a Kenwood head unit with Apple Car play. When this was all installed I did notice there was no audio from rear speakers. Unsure if this is a stereo issue or the wiring? With Kenwood now installed all speakers are working fine.
Unsure of value so make me an offer. Would rather sell the whole lot together than split. Postage UK only.
