I'm thinking of buying a 2000 Nissan Froniter Crew cab but I'm not sure if I can fit my two 12" KFC W3011 Kenwood subwoofers. I am aware that people have installed 10" shallow subs in this same kind of truck but mines are 12" and not shallow. I don't want to take the back seats out for this. Is it possible? If its not then I'll probably not buy it.
