JBL Stage3 648F 4x6" 2-Way Coaxial Car Speakers

Product Overview

Upgrade factory 4x6-inch speaker locations with the JBL STAGE3 648F 2-way coaxial car speakers. Their Plus One™ glass-fiber reinforced woofer and PEI balanced dome tweeter bring fuller bass and detailed highs to everyday listening.

Key Features & Benefits

• Plus One™ woofer: Its 10% glass-fiber reinforced polypropylene cone is designed to reduce flex for tighter bass.
• PEI balanced dome tweeter: Smooth, detailed high frequencies help bring clarity across the cabin.
• True 4-ohm impedance: The speakers can work with a factory head unit or an aftermarket amplifier.
• Recycled construction: Recycled plastics, PVC-free wiring, and soy-ink packaging reduce the product’s environmental footprint.
• Factory-size format: The 4x6-inch design suits standard OEM speaker locations in most vehicles.

Technical Specifications

Why Choose This Product?

The Stage3 648F combines a factory-common 4x6-inch size with a woofer designed for more effective cone area than a standard 4x6-inch driver. Its 50Hz–20kHz response covers bass through high-frequency detail for everyday rock, pop, R&B, and country listening.

Run the speakers from a quality head unit or add an amplifier for more system power. Their coaxial design brings the woofer and tweeter together in one speaker assembly.

Installation & Compatibility Notes

The speakers are designed for standard factory 4x6-inch locations and require no cutting or fabrication in most vehicles. Check your vehicle’s speaker location and fitment before ordering; fit can vary by vehicle.

For an amplified setup, the product description recommends a 4-channel amplifier rated at 40–75W RMS per channel at 4 ohms. Use 16-gauge or heavier speaker wire for runs over 6 feet. Grilles are not included; use factory grilles or source compatible aftermarket 4x6-inch grilles separately.
