Couple of questions, the first is in the title. Second question is, does anyone know how I could wire this up to test it? It wasn't connected to anything in the dash when I removed it (there were no speakers in it at all). I'm assuming red is hot, white is ground (?) and the bundle with the connector is for a speaker harness maybe? I have a couple of speakers I could hook up. The light orange wire has an "ANT" label but I would have figured the antenna was hooked up to the black connector hanging out the back. I've searched around online for a wiring harness diagram but have so far come up empty. TIA.
