JBL Stadium 82SSI - 8"(200mm) high-Performance car Audio subwoofers, 400W RMS, 1200W Peak, Sensitivity (@ 2.83V): 91dB, Frequency Response: 30Hz – 175Hz, Impedance: 2 or 4 ohms

SSI (Selectable Smart Impedance). Stadium subwoofers feature a dual impedance switch that lets you choose either load impedance option. This allows for a variety of system configurations when using one subwoofer or multiple.

Aero-cooled voice coil. The Stadium’s voice coil increases power and improves reliability. The woofer’s motor channels are air pumped by the cone movement past the voice coil, and the voice coil exposes the coil’s inner and outer surfaces to the airflow.

Oversized voice coil. The 2” voice coil proves you don’t have to be a heavyweight to pack a punch. It handles more power than conventional two-inch voice coils, yet it’s lighter than 4” voice coils. It strikes a balance between thermal power and low mass.

Premium integrated push terminals. Power is the lifeblood of any subwoofer. The terminals on the Stadium subwoofers accommodates 8 AWG wire (8.37mm2 cross section), which transfers low-resistance, low-loss power to the woofer, even over long wire runs.
