So...
I recently built a cinema-f20 with a Ultimax 15 driver and it sounds amazing. It plays down low to the teens, is very fast and has a lot of kick in the high bass range. This is something i want in my car.
I have an Alpine SWR-12D4 in a sub-small ported box. I don't know the exact specs of the box, but probably about 50-60 liters and tuned somewhere between 30 and 40hz. My amp is a Kicker DX1000.1. Stereo is a Pioneer DEH-x8500BT. Front speakers are a pair of Alpine SPR50. I plan on upgrading to some 6.5" components.
My car is a Volvo s80 2004. It is a sedan, so spl is harder to get than in a SUV. The s80 does have 8" speakers on the rear deck, but i want to replace those with aftermarket ones(recommendations in EU 0-150€?). It also has a ski-hole which I planned would be a great pass-through hole for bass.
What would be the best design to be used with the Alpine to get the most spl, lows and fastness? It is in a ported box now, but it doesn't have a good kick and is quite slow. A sealed box would be good, but the spl drops significantly. a horn-loaded box is what I've got in my room, but I've heard that they don't work well in cars.
I looked at the Decware Wicked one and thought about buying a second sub for that. But I've heard is isn't as good as advertised...
I don't really need trunk space, so I can use it all for as big a subwoofer box as possible. I've heard that something must always be sacrificed, spl, lows or space. That was the case with the cinema F-20. It is huge, but plays low and hits hard( and fast).
Especially the fastness is something I've come to liking very much. A ported box would be the way to go, but it is slow. How about a 4th order bandpass? I don't know how to design one though...
Would someone have any recommendations for how i design and make the box, or can someone design a box that would use the ski-hole in the s80?

For the tightest, most accurate bass, a sealed enclosure with a Qtc of 0.707 will likely get you what you want.
Yes, I know, but high sound pressure level is also important for me. I want to make the most out of my Alpine, and slamming it in a sealed box will be remarkably quieter than even a ported box. A 4th order box should have the tightness of a sealed box, as it is a sealed box, with a ported box on the other side. Am I right? But then the ported side lowers the tuning and increases sensitivity of the box?
And a 4th order bandpass would be a lot easier to port through the ski-hole, as the trunk will otherwise dampen the sound a lot.
Also, a sub in the trunk will make me have to build a box for the 8" speakers on the rear deck. If the sub is ported directly to the seating area, and the ski-hole and port are sealed against each-other, then I won't have to build a box for the eights?

A 4th-order is only going to produce significantly more output if it's tuned to be a one-note wonder.
Wait for other suggestions.
