The largest Gold driver, wired dual 2-ohm for all-out SPL passes.
The OGWZ153500AD2 is OG Audio's 15-inch Gold subwoofer, the largest driver in the Gold range and engineered to absorb extreme power bursts without failure. It is rated 3,500W RMS (7,000W Max) and pairs a 453 oz ferrite motor with a die-cast aluminum basket and a 4-layer flat aluminum voice coil, 3.9 inches across, under a paper cone. Each unit is SPL-tested and competition-certified before it ships. With dual 2-ohm impedance, you can wire the coils in parallel for a 1-ohm load or in series for 4 ohms, whichever your amplifier drives best.

Questions
Reach the OG Audio team for product questions, order support, warranty claims, and tuning help.
Start with a ported box of 2.00–3.50 cu ft tuned near 32 Hz, the recommended enclosure for this model. Treat it as your starting point, and remember net airspace is gross internal volume minus the driver's displacement.
Choose a monoblock that delivers about 3,500 W RMS at the final load you wire, 1 ohm in parallel or 4 ohm in series. Size to the RMS rating, not the Max.
Parallel gives a 1 ohm final load and series gives 4 ohm. Match the load to your monoblock's rated stable impedance, and confirm it before wiring to 1 ohm.
Overall dimensions are 15.59 × 13.26 inches and it weighs 37.8 kg (83.3 lb). Check both against your baffle and box before you cut.
