I have a 2006 Toyota Camry Solara Convertible SLE. It has a factory installed "270 watt" JBL system with an "eight inch" subwoofer with dual 2 ohm voice coils installed in a plastic enclosure behind the back seat. The surround separated from the cone. I am replacing it with a Pioneer TS-SW2002D2. I had to make an adapter ring so that it will fit the enclosure. Since the factory connectors don't "plug in" to the Pioneer, I have to clip them off and connect the wires direct. I haven't been able to find any information as per the impedance specs of the original speaker or the stereo (the one with 6-disc changer, cassette, and Sat). How do I determine which of the enclosure's wires are positive and negative and how do I wire the speaker to the enclosure to ensure that I don't drop the impedance and destroy the factory amp?
