1. Your amp may not have a high/low input voltage switch.2. You may need to calculate max voltage (using the formulas from that thread) instead of using the JL amp chart.

Other than that, the process is the same for your amp... the dials, inputs, and outputs are just in different locations.

1/2" is way too small... unless you doubled up every panel.
Try to find 3/4" and do a double front baffle (two layers of 3/4 glued together) -- throw in a few braces, too.

If you were looking more for SQ, then I'd say go bigger... but with the power you have (and your system goals), 1.25 cu ft looks like a better fit.
If SPL is your goal, then ported seems like a better fit... but with a different sub than the X.

The very nature of the X sub means it will provide hard lows... even in the Alpine recommended box size. Start there.
