JBL Stage2 45F – 4 inch (100mm) 2-Way Coaxial Car Speakers | 40W RMS

The JBL Stage2 45F 4" Coaxial Car Speakers are designed to provide a noticeable upgrade over factory-installed speakers, especially in compact or restricted mounting locations. Featuring a 2-way coaxial design, each speaker combines a durable polypropylene woofer with a PEI balanced dome tweeter, delivering clear highs and smooth, balanced audio performance.

Built as part of the JBL Stage2 range, these speakers offer high sensitivity (around 88–90dB), allowing them to produce strong output even when powered by factory head units. This makes them an ideal upgrade without requiring an external amplifier.

With 40W RMS and up to 320W peak power handling, along with a frequency response of approximately 80Hz – 20kHz, the Stage2 45F speakers provide consistent performance across a wide audio range.

The 4 inch (100mm) size makes them perfect for dashboards and compact speaker locations. Their grille-free design allows installation behind factory speaker covers, maintaining a clean OEM appearance and making them ideal for discreet upgrades.
