## Overview

The JBL Stadium 122SSI is a high-performance 12-inch car subwoofer delivering 500W RMS and 1500W peak power. Featuring Selectable Smart Impedance for versatile system configurations, an aero-cooled oversized voice coil for enhanced power handling and reliability, and premium push terminals for optimal power transfer, it’s engineered to provide deep, clean bass with professional-grade durability and flexibility.

## Description

A subwoofer that puts you in the driver’s seat: JBL believes sound quality should never be compromised and the Stadium subwoofers make sure you don’t have to compromise flexibility, either. That’s because these high-performance subwoofers feature SSI™ (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance—2 or 4 ohms—providing multiple system configurations and flexibility. A special aero-cooling design keeps the voice coil cool even at high output levels. This feature coupled with oversized voice coils increases power handling and ensures long term reliability. More power, more reliability, more flexibility—and no compromises. When you’re ready to step up, Stadium is your subwoofer

Review: Great 10inch sub!! - Very powerful. I would definitely buy another one for my next project.
Review: Clean, deep, and clear - Clean deep bass that never lets me down….JBL for the win 🏆 P.S. The box that I have the sub in does not come with it.

## Features

- 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.

*by J***N on October 29, 2025*

Clean deep bass that never lets me down….JBL for the win 🏆 P.S. The box that I have the sub in does not come with it.

### ⭐⭐⭐⭐⭐ How Deep is your Love?
*by A***R on May 24, 2025*

Buy 'em. And power them. They will put a smile on your face. These are awesome. I bought 2 for my Silverado. They sit under the back seat in a cabinet that I bought on Amazon as well. I have them in the 4 ohm setting but run them parallel. So 2 ohms at the amp. The amp is kick ass. I bought an Alpine S-A60M from Amazon as well. Life is good, real good!
