JBL Alpha 403F — 4" (10cm) 2-way coaxial car speaker without grille, designed as a compact OEM replacement delivering improved clarity over factory-fitted speakers in tight mounting cutouts. The Alpha 403F uses a 2-way coaxial design that combines a woofer and tweeter in a single 4" unit, making it a practical upgrade for vehicles with smaller speaker cutouts that won’t accommodate a larger driver. The polypropylene cone handles the temperature and humidity extremes of vehicle interiors without degrading over time. Sold without a speaker grille, making it suitable for installations where a separate or vehicle-specific grille will be used. Compatible with most head units.
