Start with what is installed
Factory System Overview
The front doors house separate woofers and tweeters, and the rear doors have full-range speakers. Some versions add a subwoofer behind the right rear cargo trim. On 2007–2014 vehicles, receiver replacement can affect satellite radio, navigation, SYNC and, with some digital-amplifier systems, fader operation. The 2015–2017 dashboard differs and requires version-specific equipment.
Inspect before ordering
Record the model year, factory audio package and any previous modifications. Listen to every channel and note faults before taking the vehicle apart. A working baseline makes the final checks meaningful.
Guide coverage
Expedition and Expedition EL. The 2015–2017 dashboard needs its own receiver and integration fitment check; the earlier dash is not a universal template for all years.
Planning guide, not a fitment guarantee. Match wiring, impedance, adapters and removal procedures to the actual vehicle. Photos show selected configurations, not every trim or a complete removal sequence.
Radio Upgrade
The 2007–2014 dash accepts suitable single-DIN and double-DIN receivers with the correct kit and interface; fold-down-face models are not recommended. With the parking brake applied and negative battery terminal disconnected, release the receiver/climate surround and lower console trim.
Connections and clearance
Make secure insulated connections and leave service length without trapping cables. Check mounting stability, vents, switches and display clearance. A plug that fits physically does not prove amplifier or vehicle-function compatibility.
Test the complete system
Verify reception, source playback, balance, fade and any retained steering-wheel controls. Restore all required dash connections before powering the vehicle for a test, following vehicle safety procedures.
Radio access and integration
The 2007–2014 dash accepts suitable single-DIN and double-DIN receivers with the correct kit and interface; fold-down-face models are not recommended. With the parking brake applied and negative battery terminal disconnected, release the receiver/climate surround and lower console trim. Carefully draw the trim assembly forward, unplug its wiring and set it aside. Four 7mm screws retain the receiver. For 2015–2017 vehicles, select a solution confirmed for the exact factory screen and audio package rather than assuming the earlier dash kit fits. Application-specific replacement-screen packages are available in 8-inch and 10.1-inch floating-screen forms, subject to configuration compatibility. Verify the retained functions, steering-wheel controls and amplifier integration before purchase, and test them before completing reassembly.
Before disassembly
Use the instructions for the exact vehicle and selected installation kit. Support removed trim and the receiver, retain fasteners by location, and stop if the wiring or dashboard differs from the documented configuration.
Shop Speaker Sizes
Browse verified collection categories, then confirm the actual installation requirements. These are not vehicle-specific fitment guarantees.

Both body lengths use comparable receiver and speaker upgrade approaches, but individual equipment still determines interfaces and fitment. Choose component speakers for the front only after confirming tweeter mounting and crossover requirements.
Front door woofers
Factory: Factory door woofer
Replacement planning: 6×8 inches, 5¼ inches with brackets
Remove the cover behind the door release and its 7mm screw, then release the handle trim. Open the pull-cup cover and remove two 7mm screws. Remove the rear-edge cover and Phillips screw, followed by two 7mm screws along the bottom. Release the sail trim, hold it clear and lift the panel off its hooks before unplugging it. Four T20 screws retain the woofer. Smaller replacements need mounting brackets. Test the speaker and check window and lock clearance before refitting the trim.
Electrical note: Verify the original driver and amplifier before choosing replacements.
Front door tweeters
Factory: 1.570 inches
Replacement planning: Compatible component tweeter
The tweeter is attached to the door panel. Removing it with its grille leaves a 1.595-inch opening. A replacement requires a secure custom mounting arrangement and insulated wiring connections; check the flush-mount housing against the opening rather than relying on tweeter diameter alone.
Electrical note: Verify the original driver and amplifier before choosing replacements.
Rear doors
Factory: Factory full-range speaker
Replacement planning: 6×8 inches, 5¼ inches with brackets
Rear access follows the same general panel-removal approach as the front. Keep fasteners organized, verify the particular panel’s attachment points and use suitable brackets for smaller speakers. Recheck door release, locks and window operation before finishing.
Electrical note: Verify the original driver and amplifier before choosing replacements.
Right rear cargo panel, if equipped
Factory: 8-inch subwoofer
Replacement planning: Compatible 8-inch subwoofer
Subwoofer access involves extensive cargo-trim removal. Its original amplifier supplies only bass frequencies, so installing a full-range driver here will not create full-range output. Check impedance before replacing the low-impedance original; a higher-impedance driver can play more quietly. New mounting holes and insulated custom wiring connections may be necessary. Inspect behind every drilling point and restore any disturbed seats and belts to the manufacturer’s installation specifications.
Electrical note: Low-impedance original; verify the exact driver and amplifier.
Tools
Receiver: trim tool and 7mm driver. Front/rear door work: trim tool, 7mm driver, ¼-inch hex driver and Phillips screwdriver; T20 driver for the front woofer screws. Cargo subwoofer access: 6mm and 7mm drivers, 10mm socket, ratchet, extension, T50 driver and trim tool. A replacement subwoofer may require a drill and suitable mounting screws.
Electrical and restraint safety
Follow the vehicle battery-disconnection and restraint-system precautions. Do not probe airbag wiring. Keep the ignition off during connection work and protect exposed conductors.
Before cutting or drilling
Inspect both sides for wiring, glass, fuel lines and safety components. Stop if clearance cannot be verified. Protect cut edges, wear eye protection and restore seat and restraint hardware correctly.
Bass and Amplifier
One measured cargo envelope below the side ledges is approximately 51 inches wide by 15 inches high, with depths of 24 and 30 inches. Check your own wheelbase, seating arrangement and usable loading space instead of treating that measurement as a guaranteed box fit. A separate enclosure offers more bass-system flexibility, while a compact powered unit can preserve more cargo room.
Power and protection
Size cable, fusing and grounding for the equipment and run length. Protect the power cable close to its source, following the wiring system requirements. Route cables clear of sharp edges and moving hardware.
Final tuning
Start with conservative gain and crossover settings. Listen for distortion, rattles and missing channels. Check heat, charging-system behavior and unwanted key-off operation before considering the installation finished.
Installation Checklist
Work through the system in stages. Test before replacing trim, then repeat the checks after everything is secured.
- Record the exact vehicle year and audio package.
- Choose whether to retain or bypass the factory amplifier.
- Confirm radio kit, interface and antenna requirements.
- Measure speaker depth, opening and grille clearance.
- Plan safe wire routes, protection and equipment mounting.
- Gather tools and follow the vehicle's safety procedures.
- Label, connect, insulate and secure the wiring.
- Test every speaker channel at a moderate level.
- Check radio sources, phone audio and vehicle controls.
- Set gain and crossovers without audible distortion.
- Secure all trim, seats and safety-related hardware correctly.
- Recheck for rattles, heat and unwanted key-off operation.
Keep a record. Save the equipment models, interface instructions, wiring changes and tuning settings. Clear notes make future service easier and help another installer understand what has changed.
