    That’s a hard part to find info on. Most places say it’s 4 ohm, one says it’s 2, another says possibly 6. 4 sounds about right. And there isn’t anything relating to power other than 10-200 watts. That would be 10 nominal, 200 max. I base that on this page.

    I’d say your amp choice is just fine. 

    As for the box, well, that depends on your final choice. In order to get there, it would be nice to know at least the minimum T/S parameters, Qts, VAS, and Fs. Unfortunately I cannot find them for this driver. Do you know anyone in the area that has a DATS? If not, you could figure them out using the info on this page, using just your computer, Audacity, an amplifier, a resistor and a voltmeter. It may be tedious, but you can do it. Having at least those 3 numbers is a good start.

    Of course, you could always base it on approximately 1/2 the volume of the Bose bass unit, and tune it by starting with a port sort of close to the original unit. From there it would be experimentation to see what works best.
