Do you think I have enough space?

[stevh0]

Im busy having my solar audio woofer recoiled and im planning on building new box for it. However, I just stumbled across another woofer (same) and I was wondering if I should just run 2, face up, port back.

Here is the thing, The KJ is tiny and I have very little space to work with.

Max size I can work with is

43.3(w)x13.7(h)x 19.6(d)

Woofer specs

Revc: 1.00 ohm
FS: 32.313 Hz
BL: 11.299 TM
Qms: 5.695
Qes: 0.483
Qts: 0.445
SPL 1w/1m: 92 dB
Vas: 146.462 L
Mms: 163.866 g
MMd: 150.000 mKg
Cms: 148.043 u MN
Xmax (one way): 0.937 inch

I need a suggestion on box tuning as well if I should run 1 or 2?
