in that case if you have no back seat. just seal it off from the trunk all forward

ok so what we got goin on all sealed off forward mounted ports and drivers at 15''h 25''w 25''d

2 6'' areos 15'' long

4.31ft^3total vol

56.52in^2 port area

3.78ft^3 net vol

and 43.59hz

this all sounding in the right direction?

tuning is too high

tuning is too high

ok lets see how you like these,

15''h 35w 25d same port size and length but its now 6 cubes at 35hz

how would i lower hz but keep it in the size range

[AI James]

longer ports, make box bigger or smaller 1 inch at a time until your where you need to be

and we're looking for thr 32-35 range right?

[AI James]

id do 34-36 range

also for 2 6" aeros to fit on your box face you'll either need to not use the outter flange or cut them so they fit...they flair out to 9 inches each. you can also do 4 4" areos and get roughly the same results.

[AI James]

also your calculations are very far off
