Answer 1

Big bass = big ported box.  FI's website shows the recommended volume and tuning frequency for this sub as you've listed above.

If you're buying one sub, I would get the dual 1 ohm and wire the voice coils in series.  It's relatively easy to find 1000W RMS amps at 2 ohm.

Answer 2

hifonics amps are awesome expecialy if your on a budget.

Answer 3

You better be working with a big pile of cash if you want those 15s powered right.

2000W Rms..x2

you are looking at about 800 bucks for a amp my man.

2 ohms
