No sound from rear speakers - Aftermarket HU

Hey guys,

I know there is a very similar topic going on about this at the moment, but I did not want to hijack the thread so here it goes:

After replacing my Symphony with aftermarket headunit with Android, my rear speakers stopped working.

I know I have speakers in the back of the car, as well as 1 in the boot. Here are the wiring looms and outputs that I currently have. I also have CAN BUS Decoder which I have connected now.

Any advice would be really appreciated, I can even pay for the correct information on how to wire all this properly.

I also have this loom, maybe I should connect it to the headunit and cut the RCA Rear L for example and connect it to the wider ISO jack that leads to car wiring where the wires have been cut on it?

Got them to work! Indeed, connected as I said above and connected the ground of the wide ISO connector, works as intended!

Sorry for spam.

I do have another issue, that is the reversing camera.

It works when key is in the lock and made a contact (so all electronics is on) and sends the video feed, but when the engine is on, it doesn't show the video.

The +12V feed is taken from reversing light, the ground should go through the RCA cable along with the video signal.
