Power Subs

He Guys i got a couple of Gemini 18" subs a friend gave to me because the are not working long story short, does anyone know where i can get a service manual or a schematic for them i tried Gemini no luck any help would be aprecieated thanks

Try geminisound.com are these active subs or passive?
