Wiring Diagram / Grommit Access for 2016 CLA200 C117
Im trying to install an aftermarket amp in my 2016 CLA200 C117 but i cant find any wiring diagram to tap into the front left and right speakers, if anyone knows the colour wires i should be tapping into or has a wiring diagram that would be great.
Also, has anyone had any success in feeding a power cable through the firewall, i cant find a single grommit to feed my power wire through, its driving me mad.
Any help would be greatly appreciated

Chris
