This is a massive sub and requires a very deep enclosure to do full justice to same. The basket alone, extends more than 10 inches into the box.
Also, this sub is rated at 800 watts RMS and is a 6 ohm DVC design. You wiring options are a single 3 ohm load or dual 6 ohm in 2 channel mode. So the JBL 1200.1 is your best bet for an amp. That amp will deliver a tad more than 800 RMS @ 3 ohms.
Now, according to the JBL technical web site, you can go ported and a 4.0 cf enclosure or bandpass. Here are the details off the site in a .pdf file:

If you want to go Competition SPL here, there are 2 other ported designs to consider for max SPL, but very peaky bass response 65/70 Hz respectively. Look here:

Does that answer your questions?

PS Depending on the enclosure design you choose, may need a sub sonic filter for COMPS and BP applications. The daily driver ported is tuned to 28 Hz and a 20 Hz subsonic filter is a good idea. If you opt for COMP Box styles, The filters will have to match the tuned port frequency you choose ... or be very close. Harrison Labs makes these type of filters and are not too expensive either. They come in an inline RCA plug in module and sold in pairs. Depending on which design you choose, we can guide you. The LP filter on this amp is fine for choosing the cutoff point for the highest frequencies the sub will get... but there is no subsonic filtering in this amp series.
