Tesla Unit Rear Audio and A/C failure (1 Viewer)

[spartagigachad]

So I have a Tesla navigation unit (made be “Seicane”). I have gotten the a/c to function in the front, but I have no audio nor any rear a/c. Does anyone know how to remedy these issues with these Tesla units? Pictures is my mess of wires, I figured the “amp-c” wire may help with audio since I figured this is likely an AMP issue… but I am a total novice. Any help would be appreciated.

How did you hook up audio? Did you use the speaker level outputs of the Tesla radio or the preamp (RCA) outputs? Are you using the stock amplifier?

Using the RCA output cables they gave me. Stock amp. I believe the blue “amp-c” wire may need to be spliced to some of the car’s harnesses but I have no instruction manual.
