I Know theres a lot of information out there but its all so confusing to me. i can barely find information on building a ported box for 2 subs, i can only find for 1 sub.

i want the size of the box to be W-41in. L-16in and H- 14.75in.

i read to get the internal you subtract 1.5 or 2X3/4 mdf.

im using 2 12" type r dvc 4 ohms

mount depth - 7.7in

mount displacement - 10.9 in

displacement front .071ft^3

manafacture dimentions -

vented

18"X13.5 inX16.5in (one sub) ( i need for two..do i double the in.?)

gross int vol - 1.7ft^3

vent are diam. - 125in^2 (12in. X 1.25in)

vent length - 22.75 in. ( the length i measure in my car was 16in so should i make my box longer to like 26in?)

vent. disp - .305ft^3

net int vol - 1.3 ft ^3

i want it tuned to 33hz

idk how to use this information

the subs are running of about 600 watts each of an AQ 1200d amp.

any help would be appreciated
