I bought a whole premium audio kit from an old 9-5 planning to just install the subwoofer to my 9-5 but I cannot understand what the 4 pin connector is, I've understood it might be a DVC thing going on but idk how I would go about getting the best audio out of it with only two pins. How could I connect the other two for them to work or is it necessary?
/edit ive learned some about it now and as far as ive understood it its not DVC but dualinputs built for redudancy. if im correct I only have to route the main power cables and ignore the others?
Parts im gonna use for the build:
Amp: DLS Performance Slim PS1.500, kompakt monoblock
Amp wiring
thats about it

ill steal sound from the rear right cable

Had to make it an edit. Even if short one
