Your probably right about a multi contact relay or small remote powered speaker switching relay device. Is your entertainment cabinets and devices over the windshield. Often the etainment cabinet inner pods are more easily removable. Hiding coax, ignition to tv disable relay and a general big mess of wiring. Lable and zipstrip all the coax,HDMI or RCA jacks bundles you might have to remove. You often find they didn't insulate very carefully and big source of solar heat. So you might want to spend some time to improve it. While most of my wiring is tidy ,that area looked like they might have used a shovel for entertainment wiring and stuff.
