hello, i have hertz hx380d (15") and i need help with the enclosure
on hertz website they're saying 60 liter (2.1 cubic feet)
but on youtube i see people with over than 3 cubic feet and the sub sounds great
the sub is 700w rms, and i have 1000w rms to give it

how much liters should i make the enclosure ?
port size? length? how many ports?

i want the sub to be sound as loud as it can, but still make it daily.

here is the details of the sub (pdf)
