This sounds like a reasonable suggestion to me.

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.

lol at "fibre"

That's how the Brits spell it. You should hear them pronounce "aluminum". //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

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

How long do you plan to run that amp? If its for awhile I would go 4-5 cu ft 36-42 hz.
