JBL GX528 Speaker

The JBL GX528 speaker is a 5.25" 2-way coaxial car speaker delivering vibrant JBL sound with 135W peak and 45W RMS power handling. Designed for easy factory fit, it drops in to standard 5.25" locations and blends with modern vehicle interiors. Its rugged, road-ready build is designed for daily driving, from highway blasts to city commutes.

With Plus One™ woofer cone technology, it increases cone surface area for deeper bass and higher efficiency, while the edge-driven soft dome tweeter delivers smooth high-frequency response and wide dispersion. Its low-impedance design draws more power from your head unit for louder, clearer sound, and the included grille keeps a clean factory look. This design also supports cleaner midrange performance for vocals and instruments.
