Is it free? If not, then you shouldn't be asking us :)

It's free. Me and him are buddies so it's no big deal. I see where you're coming from. I wouldn't sell plans until I know my plans are perfect.

Thas a lot of port area. 20 sq inch / cu foot seems like a lot for daily. Does it make that much of a difference from say 12-16 per cu foot?

And yes I agree, that port area is extremely excessive.

Would a port area of 64sqin be a little more appropriate?

This will work. We've measured many times and this will fit for sure.

I switched up the port area to 62.5 sqin.

Here's a quick look.

Yes. My 2x12 mag build I just did is working very well with 16.6 per cu foot. I was worried that was going to be too much. Turned out just fine. Beyond fine. I really like my mags.

The ~15.5 per cu foot in your last plan is within the recommended range, should be solid.

x2....My max in trunk was 40x16x30 but I could only fit a box through the opening that was 34x13.5x22.5

GM has really gotten bad about designing their truck openings...i used to have a G body (84 regal) and u could fit 4 15s in the trunk no problem

Curtis is actually putting the box in sideways. He says he liked the way his rlp's sounded with the box like that more so thats how I designed the box this time. 36" is just 2" too wide to fit a box in his trunk rear firing.

As of right now, Curtis only has 1 mag and he is using a box that has ~40sqin of port. He likes it but I bet it would get louder with less port area. Is that logical?
