Product Overview
Bring deep, adjustable bass to your car audio system with the JBL Stadium 122SSI 12-inch component subwoofer. Its selectable 2- or 4-ohm impedance helps you match the subwoofer to your amplifier, while its 25Hz–175Hz response covers deep sub-bass through upper bass.
Key Features & Benefits
- Selectable impedance: Choose 2 or 4 ohms to suit your amplifier’s preferred load.
- 500W RMS power handling: Pair it with a compatible mono amplifier for substantial subwoofer power.
- Aero-cooled voice coil: Moving air helps dissipate heat during high-output listening.
- 92dB sensitivity: The specified sensitivity helps you assess the subwoofer’s output efficiency.
- Push terminals: Integrated terminals accept speaker wire up to 8 AWG.

Why Choose This Product?
The Stadium 122SSI gives you a choice of impedance without managing separate dual-voice-coil wiring configurations. Select the load that matches your amplifier, then build your system around the subwoofer’s power handling and enclosure needs.
A ported enclosure tuned to 30–35Hz is recommended for low-frequency extension and output. A sealed enclosure is an option for tighter, more accurate bass. The described uses include daily listening, sound quality listening, and enthusiast builds.
Installation & Compatibility Notes
Check your enclosure’s cutout and available mounting depth against the listed measurements before installation. Match the selected 2- or 4-ohm load to your amplifier’s ratings.
The source recommends a mono amplifier rated at 400–500W RMS at the selected impedance. It also identifies the JBL Club A5055’s 500W RMS sub channel at 2 ohms as a match; for 4-ohm operation, it gives a 300–500W RMS mono amplifier recommendation. For a ported enclosure, the source suggests an 80Hz low-pass crossover and a 25Hz subsonic filter.
Frequently Asked Questions
How do I select the Stadium 122SSI’s impedance?
Use its built-in selector to choose 2 or 4 ohms, matching the selected load to your amplifier’s output rating.
What amplifier power is recommended?
The source recommends a mono amplifier rated at 400–500W RMS at your chosen impedance. It also gives a 300–500W RMS range for a 4-ohm mono amplifier.
What enclosure should I use?
A ported enclosure tuned to 30–35Hz is suggested for more low-frequency extension and output. A sealed enclosure is suggested for tighter, more accurate bass.
What dimensions should I check before fitting it?
Confirm that your enclosure accommodates the 28.5 cm cutout diameter and 18.0 cm mounting depth.
