Ok, so heres a question. In order to keep the box size to a minimum, what about 2 10" type R's? Probably in 3-3.5cf tuned to 32hz. Is that an option? Of course upgrading the amp to 1000rms.
I think 3.5cf for anything is the absolute maximum. 3cf box is ideal.
you guys are welcom to offer any other subs that's work well with that space and 1000-1200rms. And I also think im geared to a final 2ohms output.
