I have the infinity system and the drivers 6x9 is out. All other speakers work fine. I pulled the door panel to check connections and all were good... speaker still dead. There's a 10-wire harness that goes to the speaker... . yes, 10 wires. I suppose I'll just pony up and buy a speaker..... hope that's it. Is there anyone that could tell me a way to check the wiring coming in just in case. I presume the black thingy that's held onto the speaker with two brass torx head screws is some sort of amp?
