JL Audio 12TW3-D4 12 inch Shallow Mount Subwoofer 3.5" Mounting Depth: a 12-inch subwoofer rated 400 watts RMS, offered in 2 ohms or 8 ohms.
Published parameters: Fs 15.2 Hz, Qts 0.531, Vas 48.73 L, Xmax 4 mm. Those three numbers decide the box; the amplifier only decides how loud it gets.
The manufacturer recommends 0.8 cubic feet sealed or 0.95 cubic feet ported. We cut enclosures to those figures; ask if you want this driver boxed.
Pair the amplifier against RMS, not peak, and wire the voice coils to an impedance the amp is stable at.
