The bass in my 2002 BMW 325 wagon (touring) is quite horrible, so I decided to investigate what is back there. The 6.5" 2ohm drivers have an FS ~72Hz, and Qts ~.75. They're in small enclosures, and are quite a strange shape. I gave up on putting anything else in that location.
However, there is a lot of space above the spare tire, so I thought of building a tapped horn subwoofer that would mount on top of the spare tire and run off the stock amplifier.
I figured I could use 4 TangBand W3-1876S woofers in a horn-loaded box under the back of the car. Thoughts?

1/4 wavelength enclosure would need a decent amount of space I think you'd be better off with a simple ported enclosure cabin gain adds a lot down low
1/4 wave at driver's Fs would be ~5 feet, 1.55 meters. I was thinking of trying to build a spiral out of CNC'd MDF pieces.
It's pretty hard to beat a sealed box with lots of xmax in a car. Cabin gain is your friend. And cabin gain doesn't work on vented subs and tapped horns below their resonant frequency.
Agreed, but he has a station wagon to work with. I would think station wagons, vans, and suv's would work more like small rooms where you would benefit from horn loaded enclosures.
