Aftermarket radio done, how to install subs?

Okay so I got my wiring harness installed I’m my 2003 e320 (I used scoshe harness) and it is sounding nice, now I want to add subwoofers. How exactly would I go about running the av wires through the trunk to my head unit? Also wanted to wire a backup camera but can seem to figure out how to run the wires

there is a channel dow the sides of the seats. you need to take the back seat out and remove the kick panels and move the carpet back.

I tried googling info on it before and found nothing, that’s why I came here, all the e320 info I lookup on are older models and are different
