Ok just to complicate things, I just bought a second matching sub so now I have to redesign the box. Should I have to two drivers share the same space or treat it like two boxes sharing 1 side?

No! No sorrys! I'm getting a lot of good information out of this. So this might make it easier. This is the song I usually use to test out my car stereo: So if that will sound better tuned to 40 then that's perfect. Nothing I listen to really goes lower than that, or rarely.

It's weird, if I plug Rockfords suggested box and port dimensions it tunes the box to 41.69 hz. Isn't that too high?

What happens when it goes over 100?

98 ft/s at 33 hz is the peak at 500w input. Is that RMS or peak measurement? At 1125w (which is the max the amp will put out) it jumps up to 145 ft/s. I'll have to keep it turned down to about halfway.

If I narrow the port down to 1.5" x 12" it shortens up considerably, and reduces the port air velocity quite a bit. Is 1.5" wide too small?

Sorry, math. 8.29" longer port which makes it too long for the box. I have to do some reworking.

I mostly listen to classic rock and metal but I do still like some boom. I had originally tuned to 35 hz but I found I got a LOT more output at 40. I was worried that it wouldn't be loud enough at 35. Should I post up the 35 tune? edit: ok I guess I just need to make the port 1.29" longer to...

Everything else looks ok? Thanks for looking!

If that means the port air velocity chart, it maxes out at 78.2 ft/s at 38hz. Is that too high?

I picked up a Fosgate P1S2-8 and I'm working on a slotted box for it. The specs call for a .65 ft3 box but when I put it into WinISD I found I got more output in a 1.5 ft3 box with the port tuned to 40 hz. Would you mind looking at this and let me know if it looks ok? This is my first time...
