8" Bravox for HT enclosure help!

I just bought a 8" Bravox Audio subwoofer (PXW8D-2). I have a 180-240rms plate amp that I will be using to power this. I was looking to build a sonotube enclosure or just a regular ported enclosure (don't matter to me). I just need to know what size enclosure (sealed and ported) would be best for this subwoofer in the home. Space is not a concern.

If not a problem, I would like to know the optimal enclosure ported for 1 and 2 of these also.

My problem is that the lowest my amp will wire down to is 500rms @ 4ohms. I would like to eventually try it in the car, or I might just have to find another one in the future.

But back onto the main topic..It will be used for movies, but a little more for music.

Here are the Parameters:

Xmax (mm): 7.6

Levc (mH): 0.42

Krm (mohms): 1.18

Kxm (mH): 21.0

Erm :0.82

Exm: 0.56

Freq. Resp. (Hz): 30-4500

Power (max/nom): 360/180

Thanks!
