Hi all

Classic one here got myself a B6 Bex 04 plate coming soon and just wipped the stereo out and found out ill possibly need a adaptor harness for a aftermarket stereo.... i used to own a S3 8L and had spent years modding it lovibg it but sold up and moved on and kn thag it was a similat part amllified system that took about a konth of fiddlinh to sort......done some research before posting this and looked in stickies and havent found a answer but have found some info.......

Looks like 2x rear speakers are amplified and have seperate connections on the right of the iso blocks in picture 3

There is a yellow colours plug with is aerial related and i know i wont need in the middle

Also anyome know whay picture 4 is is it power ??

Anyone know of a harness or way around these wiring these rear speakers also ?.? See pics attached

Any replies wiuld be brill manys thanks

Update **

I think all speakers are in the ISO connectors those 2 cable are for nav only i think .... Ive bought a harness witch i think is correct however i also found this info after trying and failing to get power on aftermarket HU (please have a read before continuing reading thia post) ....

I dont understand the part on fitting a relay and wiring to perminant live ... I understand red cable under steering rack cowling and that its doesnt support enough current to power HU on its own. However it does stay live until keys are pulled out. Anyone got further clarity on this or pictures would be brill ??

Many thanks
