'''2'''' 12 hdc3 in a regular cab pickup truck no blow through

[bassaddiction]

4.6 befor displacement is right.

would that be good for 2 12 aq.

how should i port it, at 36 hz. what size port or tube should i make.

Rectangle port parallel with the back of the cab? Like 3" slot, or something in that ballpark? Aiming it along the back of the cab firing it up in the direction of the rear window? That's probably how I'd choose. Youre not planning to do the pro audio speaker in that spot like that other box you have pictured, right?

I second cleansierra for a flat port along the back wall. My hdc3box in my reg cab peaked at 30htz in a 3.4cu box before displacement. Port was 3x14.5x28 long. You could probably get away with 3 x 28 along the back and about 18 into the box. I thought about building a similar box for mine.
