4 12" PORTED dimension inside! need port size!

[defdaboss 10+ year member]

Hello everybody. been a minute since i been on this site. you guys been very helpful and i never had problem with my system. not even ONCE! mad prop to those who help me in the earlier build.

now its time for part 2.. time to switch from seal to port.

this is what i have now...

those are 2 fosgate amp 800.2 and 4 12" fosgate punch subs

now i want to build this box.

ONLY DIFFERENCE IS THE WOOD WILL BE 3/4 AND the DIMENSION CAN ONLY BE 17" H x 17"L x 62"W

they are charging 280 to build it this way and i figure i go ahead and build it myself with the help of car audio.

im not good with alegebra but im good at measuring and buildin box.. the whole port measuring inside and multiply confuse me.

so my question is.. what will the port size be with this dimension per chamber for something as 35hz??? i look thru the free box dimension and nuthin i could use to build 4 12" together.

hmmm one thing your gonna want to consider, is how are you going to fit that box into the trunk? looks like right now youve got 2 seperate enclosures, that seems the only plausible way.
