JBL's GT-BassPro12 powered subwoofer adds a blast of bass to your vehicle so you can really feel your music's impact as you drive. JBL designed this bass system to shine in the car environment, tuning it for tight, responsive low notes.
Unique port for compact design
The enclosure features JBL's unique Slipstream port, which offers shorter length with a wide-mouth opening that reduces port noise and distortion. This means that JBL can build a more compact enclosure, and still get great performance from this hard-hitting sub. The medium-density fiberboard construction offers strength and durability under extreme conditions, while the carpet covering and stylish metal grille help protect your investment.
