Can someone help me figure out my box volume and tuning...dimensions inside

[pcchris]

Ok i took the measurements of the box here goes

_The Box_

28" Deep

38" Tall

48" Wide

_The Port_

21" Deep ---(measured from where the port wall ends inside the box)

35" Tall ---(measured from inside the port)

9" Wide ---(measured from inside the port)

and Its double layer 3/4 birch on all sides

My bad noob hiding behind wall now lol

is this box size okay for 4 18 hdc3s?

or should i rebuild? someone told me rebuilding to 24 cubes will make a difference and that my current box is too small since they require 6 cubes a piece....

also im running 4 bxi 2608ds

1 bt80 shuriken batt

1 300 amp ho alt

2 runs of 0 +/-

could my bass be sounding this way because i need more batt to feed my amps?

i know i need more batt but my voltage doesn't seem to drop to hard...(according to the dash) so ive been putting off getting the other 3...

my whole reason is because this setup is not creating the throat hurting pressure and air movement i intended ---so is this BOX, BATT or BOTH?

Kranny my ports down the middle would that make a difference?
