I Have a Mofo Power Aqoustik 12" and i need a new bass box for my Honda Civic 1991. I need a more compact box then the one i have cause i don't have any space in my hatch to put my hifonics amplifier. .... Can anybody help me please? Or if i use the normal box which was designed for the sub will it take less space ???
How can i design my own bass box with these or can u give the the lengths of the box so i can build it myself ??

2400 watts power handling

270 oz. magnet

3A" BASV/Kapton Hybrid 18 AWG Voice Coil

Ported box: 1.75 cu..Ft.

Tuning: 40 Hz

Port size: 3A"(dia)x8.75A"(length)

Why do want 2.4cuft when they recommended volume is 1.75cuft. Am I missing something? Are you wanting to build a cube shaped box or something else?

change the length or diameter of your port tube and the reason he said 1.75 is because you posted the wrong info in the first post

oh and along with that if you want an SQ box lke you said your not going to want the box tuned to 40 hz you should keep it between like 25 and 35 if im not mistaken

To tune 2.4cuft to 45hz use 1 4" port 4" long or 2 4" ports 11" long.

Hope this helps
