12" Q Enclosure Question

[tooshort_128 0]

I just got rid of my suv and bought a car and I plan on putting my Q in my car but don't want to use the same box because it's just too big. Right now it's in 2.5 cubes at 32. I was thinking about going sealed for SQ but then again I want it to be loud enough for the sound to come from the trunk into the cabin of the car. I'm a low end feind, so I definitely want the lows. For a mixture of SQ and SPL while retaining some trunk space I was thinking 1.8cuft (FI recommended minimum) tuned low to like 28-30. How would this work compared to going sealed in 1.5 cubes?

I think the ported box would give you better lows than the sealed box for most music you'll listen to.

so the ported would have better low end but will it be as musical as 1.5 sealed?
