well i made a box for two kicker comp vr 12s. Net volume of box was 4.5 ft^3 @ 34 hzs. This was also my first time using aeros, i used 2 4". so anyways i got the box done put in my car to replace the prefab sealed box i had and it seems to have less output. :furious:

Probably shoulda used some bigger diameter aeros.
Did you used flared?
The port area is only like 25. Suggested amount is 12-16 per cubic foot, which would be at least 54 in your case. Can you fit two more 4" aeros?

i thought i messed up with the tuning but i took the aeros out again and recheck the length and it checks with what the port length calculator on psp so im not sure

yeah they were flared. might be able to fit two more but it will be cutting it close. i guess ill just have to mess around with it some more tomorrow
