Installing rear speakers in a Toyota FJ Cruiser can significantly enhance the vehicle’s audio quality, especially for passengers in the back seats. The FJ Cruiser’s unique rear cargo area layout and factory speaker setup present both challenges and opportunities during an upgrade.
Most models come with basic 6.5-inch rear speakers mounted in the back cargo panel, which can be replaced with higher-quality aftermarket units that offer better clarity, bass response, and overall sound performance. The process involves removing interior trim panels, disconnecting factory wiring, and connecting new speakers—tasks that require careful handling to avoid damaging interior components.
With the right tools, compatible audio equipment, and basic knowledge of car audio systems, most enthusiasts can complete this upgrade in under two hours. This guide walks through the necessary steps, tools, and tips to help ensure a successful rear speaker installation in your FJ Cruiser.
Tools and Materials Needed for FJ Cruiser Rear Speaker Upgrade
To successfully install new rear speakers in a Toyota FJ Cruiser, gather the essential tools and materials before beginning the project.
Best Studio Monitors Under $200You’ll need a trim removal tool or a flathead screwdriver with a cloth wrap to avoid scratching surfaces, a socket wrench or ratchet set (usually 10mm sockets), wire strippers or crimping tools, and possibly a wiring harness adapter if your new speakers don’t directly connect to the factory harness. Other helpful items include electrical tape, butt connectors or soldering equipment for secure connections, and a multimeter to identify positive and negative wires.
Most aftermarket speakers come with installation hardware, but checking compatibility for mounting depth, impedance, and speaker size (typically 6.5 inches) is crucial to avoid interference with internal components. Having all materials on hand streamlines the installation and reduces the chance of damaging the vehicle’s interior.
Step-by-Step Installation Process for Rear Speakers
Begin the installation by disconnecting the negative terminal of the vehicle’s battery to prevent any electrical shorts. Next, remove the plastic trim panels covering the rear speaker locations—these are held by plastic clips and usually start at the bottom near the tailgate.
Use a trim tool to gently pry each section, working your way around the edges. Once the panels are off, disconnect the factory speaker wiring harness or unplug the connector and unscrew the three mounting bolts securing the stock speaker. Carefully pull out the old speaker and set it aside.

Secure the new speaker with the original screws or supplied hardware, reattach the trim panel, and repeat for the other side. Reconnect the battery and test the audio system before fully reassembling.
Choosing the Right Speakers for Your FJ Cruiser
Selecting the correct aftermarket speakers is critical for both performance and compatibility. The FJ Cruiser's rear speaker openings are designed for 6.5-inch coaxial speakers, though some models may fit component sets with modifications.
Focus on key specifications such as power handling (RMS), sensitivity (measured in dB), and frequency response to ensure optimal sound output from your head unit or amplifier. Speakers with higher sensitivity (90 dB or more) perform better with factory stereos that have limited power output.
Look for models with polypropylene cones and rubber surrounds for durability and resistance to temperature changes—important in a vehicle often used for off-road adventures. Brands like JL Audio, Kenwood, and Polk Audio offer FJ-compatible speakers with enhanced bass and clarity. Always verify fitment using online vehicle-specific databases or manufacturer guides before purchasing.
