Default Question about bandpass


Is this a good starting point? 1 cube sealed 3.5 ported... I have a 97 maxima and just this morning I realized my seats don't fold down. So I'm thinking an external port firing through the opening for the arm rest. However I'm a little rusty on designs. I was just planning on building the port to match the opening but as far as a starting length I have no idea. I'm wanting my roll off to be around 25 Hz cause I love me some lows so a 3db gain (theoretically) above 26-50hz will work wonderfully.
Subs are 2 DD 1510 with an audiopipe 3000. Any help would be greatly appreciated.

The opening that's begging for a 4th order

Wouldn't for it to be a bandpass need the magnet and port in the section and in the sealed 1cubic foot have the top(cone/dust cap) be in the sealed part? So with what you have the subs motor would be facing towards the inside of the car and the cone towards the rear?

Well was it a single 15" or 18" and if so what volume did you have for the sealed and what air volume did you have on the ported section? Lastly, what did you tune the ported part too and how did it sound?

What would u recommend sealed&ported+tuning for a 15" DC XL m2 or an 18" Crossfire XS V.2
