JBL’s jaw-dropping Stage 800BA subwoofer measures less than a cubic foot and delivers an impactful performance. Inside the slot-port enclosure is a system tuned 100 watts RMS class D amplifier and 8″” (200mm) subwoofer. The compact Stage 800BA will provide tight, deep bass in any car audio system. The subwoofer and amplifier have been engineered as a system to ensure great distortion-free bass even at high output levels. The rigid lightweight polypropylene woofer supplies the signature punch and clarity of JBL bass. When it’s time to show and shine, the bass EQ control is good for a 9dB boost. With the legendary JBL® logo stamped front and center on the dust cap and the oversized protection bars, you have a bass system ready to do business.
