Wanting to add subwoofer/amp to Uconnect 5 HK system. What all is needed for a plug and play harness?

[Solracer]

Don't want to tap into any wiring and don't want to have to tap into the head unit.

Are there any harnesses available? I know for Uconnect 4 there is, but can't seem to find any info on Uconnect 5.

Also, down the road I want to replace mids and highs along with an amplifier for those.

Thoughts?
