I might as well add: in the red/black pair, black, with the larger terminal, is POSITIVE. In the gray/brown pair, gray, also larger terminal, is POSITIVE. Now begins further learning for me. The former owner replaced the factory radio with a nice Sony CDX-GT310. The old blown sub’s 12-pin connector, inside the console, was disconnected. Currently four speakers are “live”: L and R fronts in-dash and L and R rears, 5-1/4”, in the roll bar. I was able to get the new, Audiopipe 6.5” sub into the factory center console box, by Dremeling down the interior “fins” and drilling four new mounting holes. Had a devil of a time using the supplied clips over the mounting holes as they kept jumping onto the sub magnet. Patience, rubber cement and electrical tape finally held them in place. Now the real fun begins: Connecting the 12-pin harnesses failed to power the sub. The good news is nothing smoked, crackled, or blew up!! So, I shall seek a wiring diagram for the Sony and try to figure out what goes where. Or......replace the Sony with a BlueTooth unit and make a fresh start. For what it’s worth, the rear 5-1/4”s are pretty bassy and I had a great sense of accomplishment replacing the old sub. Again, thanks to all!!
