JBL Stage 122 12" 250W Car Subwoofer
Description
Description
The JBL Stage 122 12" 250W Car Subwoofer delivers 250W RMS / 1,000W peak power at a single 4-ohm impedance, individually voiced by JBL's transducer engineers to deliver that unmistakable JBL signature bass character. If you want a straightforward, no-frills 12" subwoofer with proven JBL engineering at an accessible price point, the Stage 122 is the move.
The Stage 122 is built around a polypropylene cone — lightweight and rigid for accurate, low-distortion bass reproduction with frequency response reaching down to 34Hz. The hi-roll rubber surround maximizes cone excursion for deep, punchy bass while maintaining long-term durability in demanding in-car environments. The 2" (50.8mm) voice coil handles the 250W RMS thermal load efficiently, and the single 4-ohm impedance keeps wiring simple — connect directly to any mono amplifier rated at 4 ohms without worrying about DVC wiring configurations. Sensitivity reaches 91dB at 2.83V for strong output efficiency. Frequency response spans 34Hz to 200Hz, covering the full subwoofer range from deep sub-bass to upper bass punch. Each Stage 122 is individually voiced by JBL transducer experts to ensure consistent sonic character across the lineup.
Pair the Stage 122 with a mono amplifier rated 150–250W RMS at 4 ohms. The JBL Stage GT 50011 at 300W RMS (4 ohms) is a natural match — slightly over-powered, so keep gain conservative. Use a ported enclosure tuned to 35–40Hz for maximum output, or a sealed enclosure for tighter, more accurate bass. The single 4-ohm impedance makes this one of the simplest subwoofers to wire and integrate into any system.
Why Choose the JBL Stage 122?

Amplifier & Enclosure Recommendations
Pair the Stage 122 with a mono amplifier rated 150–250W RMS at 4 ohms. The JBL Stage GT 50011 at 300W RMS (4 ohms) works well — keep the gain conservative to stay within the sub's 250W RMS rating. For enclosures: a ported box tuned to 35–40Hz maximizes output for hip-hop, EDM, and bass-heavy music. A sealed enclosure delivers tighter, more accurate bass for rock, jazz, and everyday listening. Set your amplifier's low-pass crossover at 80Hz and subsonic filter at 30Hz for ported enclosures. Use 8 AWG or heavier speaker wire from amp to sub, and 4-gauge power and ground wire to your amplifier.

Frequently Asked Questions
Q: What amplifier pairs best with the Stage 122?
A: A mono amplifier rated 150–250W RMS at 4 ohms is ideal. The JBL Stage GT 50011 at 300W RMS (4 ohms) is a natural match — keep the gain conservative to stay within the sub's 250W RMS rating. Contact us at Trinity Car Audio for a specific amp recommendation.
Q: Is the Stage 122 a single or dual voice coil subwoofer?
A: The Stage 122 is a single voice coil (SVC) subwoofer at 4 ohms. This makes wiring simple and straightforward — connect directly to any 4-ohm mono amplifier without worrying about DVC wiring configurations. If you need impedance flexibility, consider the JBL Club 102 or Stadium 122SSI with SSI™ selectable impedance.
Q: What enclosure type should I use with the Stage 122?
A: A ported enclosure tuned to 35–40Hz maximizes output for bass-heavy music genres. A sealed enclosure delivers tighter, more accurate bass for everyday listening. Contact us at Trinity Car Audio for specific enclosure volume and tuning recommendations for your vehicle.
Q: How does the Stage 122 compare to the JBL Club 102 and Stadium 122SSI?
A: The Stage 122 is the entry-level option — single 4-ohm, 250W RMS, straightforward wiring. The Club 102 (10") adds SSI™ selectable impedance and a double-stacked magnet at 350W RMS. The Stadium 122SSI (12") is the flagship — SSI™ selectable impedance, aero-cooled voice coil, and 500W RMS. Choose the Stage 122 for a clean, simple first subwoofer upgrade; step up to the Stadium 122SSI for maximum output and amplifier flexibility.
