JBL Stage3 58F 5.25" 2-Way Coaxial Car Speakers

Product Overview

Give your car’s audio a clearer, fuller sound with the JBL Stage3 58F 5.25-inch 2-way coaxial car speakers. Their Plus One™ glass-fiber reinforced cone and PEI balanced dome tweeter bring detailed highs and more controlled bass to compatible factory speaker locations.

Key Features & Benefits

• Plus One™ cone: Its 10% glass-fiber reinforcement adds rigidity, helping deliver tighter bass and more accurate midrange.
• Balanced dome tweeter: The PEI tweeter provides smooth high-frequency detail designed to spread evenly through the cabin.
• Efficient design: The 89dB sensitivity and 4-ohm impedance suit use with a factory head unit or an aftermarket amplifier.
• Recycled materials: Post-consumer recycled plastics and PVC-free wiring bring environmental considerations into the speaker’s construction.
• Factory-location installation: Designed for standard 5.25-inch locations, with no cutting or fabrication required in most vehicles.

Technical Specifications

Why Choose This Product?

The Stage3 58F is made for everyday listening across music genres when you want an upgrade in a 5.25-inch format. Its cone design increases effective cone area beyond a standard 5.25-inch driver, supporting more bass output without moving to a larger speaker size.

The stated frequency response spans 55Hz to 20kHz. That range covers bass, midrange, and high-frequency detail in one coaxial speaker, while the 4-ohm design works with factory head units and aftermarket amplifiers.

Installation & Compatibility Notes

These speakers are designed for standard 5.25-inch factory locations and fit most vehicles with compatible openings. Check your vehicle’s speaker size and mounting requirements before purchase; fit can vary by vehicle.

You can run the Stage3 58F from a quality factory head unit. For an amplifier setup, the source recommends a 4-channel amplifier rated at 40–75W RMS per channel at 4 ohms. For speaker-wire runs over 6 feet, use 16-gauge or heavier wire to help minimize resistance losses.
