Hi Together From a reliable source, I know that the installation of the original DAB and subwoofer in my V70 III can be done without factory options. Now I want to clean all of this, i.e. to the extent possible exactly to the factory installation. I know the positions of the devices and also their protection. (Sub 25A and DAB 5A in the rear fuse box) That brings me to the first question. Does anyone know which cross section of Volvo is installed for the SUB? Probably 4mm2, I would have now 2x 2,5mm2 v The second question would be where can I get this Volvo plug? (See pictures) Twice power and once Fakra. But the Fakra is not the standard dual port connector. Greetings and thanks Christoph
