DD35k means 3500 series. The 2/2 is Dual 2 like you said.

I would start at DD's site and see what they say. depends what your willing to loose for space.

The rated doesnt really mean a whole lot with DD. More important is user knowledge. I personally would throw 2k to the sub. Just make sure your not clipping or anything.

 
came up with this let me know if this is ok any and all help thanked in advance.

ext-18 (h) x 14- (d) x 40- (w)

int-16 (h) x 12- (d) x 38.5- (w)=

7392 cu in/4.277 cu ft/11977 litres

7392 x0.77 =5691.84 cu in (0.77=spk+port disp.

5 x corner dispersion(32 cu in ) =160 cu in

5691.84 -160 =5531.81 cu in /3.2 cu ft.

3.2 cu ft x 16 =51.22 sq in divided by 16 =3.2 inches wide =77mm port width.

internal L vol. box after spk/port/corn disp.

=3.2 cu ft

=5531.81cu in
