    2 ab hd 12s Box build in a reg cab

    Alright the plan is to put both of these twelves in my reg cab truck. I can probably fit 4 cubes if I try but I would like to stick around 3.5. The box will be externally aeroported with 3 4" or 1 8" tuned to 38. My question is how will these subs sound in a 3.5cuft box? Should I go bigger and loose even more space?

    Re: 2 ab hd 12s Box build in a reg cab

    Bob (owner of AB) says to keep them in 2-2.5 cubes. With my one HD 12, I went from 1.8 cubes with 24 sq. inches of port, tuned to 40 hz, to 2.0 cubes with 48 sq. inches of port tuned to 40 hz and gained 1.7db with the same equipment and similar box design (45'd corners and resin all throughout)

    Re: 2 ab hd 12s Box build in a reg cab

    I'd give it 4 cubes tuned to about 35 hz with plenty of port area, like 70+ sq. inches

    Whatever you say man, but that's only 50 sq. inches of port. 4 cubes x 16 sq in. = 64. I saw pretty big gains going from 16 sq. in. per cube to 20 sq. in. per cube.

    Its also a flared aero. If it was a slot port I would totally agree with you. Am I wrong in saying that you can get away with less port area if your goin aeros as long as they are flared?

    You can get away with less port area with aeros regardless; being flared does also help. You should be fine.. will sound pretty nice IMO.

    You could be right there. Anyway, very nice subs, I'm gonna be sad to see mine go here soon, but it just won't take the kind of power I'm looking for

    Re: 2 ab hd 12s Box build in a reg cab

    Current plan is a wall with an 18" IA Warden with a pair of AB 120.1's.....that could change, but sounds good to me right now, lol

    I used to have an 18 in my trunk car. You'll like it even more with a wall
