JBL Stage3 868F 6x8" 2-Way Coaxial Speakers

The JBL Stage3 868F is a pair of 6 x 8-inch, 2-way coaxial car speakers designed as an upgrade for vehicles with compatible factory speaker locations. They combine a woofer and tweeter in each speaker, providing a straightforward way to replace worn or limited-range factory speakers. This grille-free version is intended for installations that retain the vehicle's original speaker grilles or panels.

With 70 watts RMS and 560 watts peak power handling per speaker, the Stage3 868F is suited to systems powered by a head unit or a compatible aftermarket amplifier. Its 91 dB sensitivity at 2.83V supports efficient output from available system power. The 50 Hz to 20 kHz frequency response covers bass, midrange, and high-frequency duties within a full-range door or rear-deck speaker position.

A PEI balanced dome tweeter is integrated into each coaxial speaker for high-frequency reproduction. JBL specifies this tweeter design for clear treble response at higher output levels. The coaxial layout keeps the installation focused on a single speaker location rather than requiring separate tweeter mounting.

The woofer uses JBL's patented Plus One cone architecture, which increases usable cone area compared with conventional designs in its class. Its laser-etched cone is reinforced with 10% glass fiber and is designed to support low-frequency output. The cone treatment also creates a forged-carbon-fiber-style visual effect under changing light.

Stage3 Gen2 construction incorporates post-consumer recycled plastic materials, PVC-free wiring, and soy-ink packaging. A true 4-ohm nominal load is designed to account for resistance elsewhere in the audio system and help use available power from a compatible radio or amplifier. For a complete upgrade, verify vehicle fitment, mounting clearance, and factory wiring before installation.

Key Features

• 6 x 8-Inch Coaxial Design: Combines woofer and tweeter functions in each speaker for a compact replacement solution.
• 70W RMS Power Handling: Handles 70 watts continuous power per speaker for compatible factory or amplified systems.
• Plus One Woofer Cone: Provides increased cone surface area to support sensitivity and low-frequency output.
• PEI Balanced Dome Tweeter: Delivers integrated high-frequency reproduction from the coaxial speaker assembly.
• True 4-Ohm Technology: Uses a 4-ohm nominal load designed for efficient use of available system power.
• Glass-Fiber-Reinforced Cone: Uses a laser-etched woofer cone reinforced with 10% glass fiber.

Design & Installation

The Stage3 868F uses a laser-etched woofer cone with 10% glass-fiber reinforcement, along with a PEI balanced dome tweeter. JBL also specifies post-consumer recycled plastic materials, PVC-free wiring, and packaging printed with soy-based inks. These speakers are supplied without grilles, allowing them to sit behind compatible factory trim or existing vehicle grilles.

Confirm that your vehicle accepts a 6 x 8-inch speaker and check mounting depth, mounting-hole alignment, terminal connection style, and door-panel clearance before ordering. The package includes mounting screws, spade clips, foam gaskets, logo badges, and a mini owner's manual. Use the included foam gaskets as appropriate for the mounting surface, and match amplifier setup to the speakers' 70W RMS-per-speaker rating.
