A full 12-inch cone in just 4.96 inches of depth.
The OGSS12500AD4 puts a genuine 12-inch cone into a 4.96-inch overall depth, built for installs where a full-depth subwoofer will not fit. It is rated 500W RMS (1,000W Max for 10 ms) and built around a 63.69 oz ferrite motor, a die-cast aluminum basket, and a 2.5-inch, 4-layer copper voice coil on a black aluminum bobbin. Every unit is SPL-tested and competition-certified before it ships. Dual 4-ohm coils wire in parallel for a 2-ohm load or in series for 8 ohms, giving you room to match your amplifier's stable impedance.

4.96 inches overall, in a 12.59 × 4.96-inch package with a full 12-inch cone. It is built for installs where a full-depth sub will not fit, so check your seat and cab clearances before ordering.
Plan for 500W RMS continuous. The 1,000W Max rating applies for 10 ms, so match the amplifier's clean RMS output to the 500W figure.
Parallel gives a 2 ohm final load and series gives 8 ohms. Choose the load that matches your amplifier's stable impedance.
Rated response is 42–300 Hz with Fs at 42 Hz and 84.8 dB sensitivity. Linear excursion (Xmax) is 0.39 inches.
