New build. :) memphis mojo 15

This....the port length is wayy too small, if you have 30sq in of port with 3 cu/ft then youd need about 20in of port length for 33hz, it drops to 16.5 with 3.5 cu/ft, yours looks like its more like 12-13in long
THe port is 14.5 in long I believe and the box it 3.89 cubes (4.66 cubes less port and sub displacement)

 
I only have a 750.1 pushing the sub right now, I bought a new amp capable of 1 ohm.

The Mojo is wired @ 4 ohm and the kicker is probably pushing 400w.

The sound is low, its not like SPL 40 or 45 I can say that for certain. But I cant sat that it is exactly 33 hz but it is lower than the kickers that I had.

How can I test to see what frequency the box is tuned to?

 
NEW amp arrived today!!!!!
