I bought a couple Pioneer Premier titanium 12's from a guy i used to work with a few years ago, and i now have a much smaller car and only use one. i have a friend who wants to buy the other one, but i can't seem to find any information on these speakers. i'd rather not have to pull the sub out of my trunk in the snow to try to find a model number that i don't recall seeing on the several occasions i have had them out of boxes, does anyone know anything about these subs? i know it has a dual voice coil, 800W max, 400W rms, but other than that am somewhat clueless about them. any help would be appreciated. thanks.
