Start with what is installed
Factory System Overview
PAC's RP4-FD11 provides one interface route, but its 2013–2014 F-150 coverage is restricted to the specified base-model center-stack radio. A broad year listing does not override that restriction. The interface alone does not retain SYNC, and its factory-amplifier arrangement does not preserve front-to-rear fade. Resolve any additional retention hardware before accepting those tradeoffs.
Vehicle-specific checks
Make a written checklist for steering-wheel controls, hands-free calling, USB, camera display and any other fitted functions. Confirm each item against both the chosen receiver and interface. This guide does not approve a complete package for navigation, color-screen or premium-audio combinations.
Choose a signal path
Keeping the factory amplifier can make a modest upgrade simpler, but its input requirements, turn-on method and filtered outputs still matter. Bypassing it means planning new connections and appropriate amplification for every speaker you intend to use.
Do not tie amplifier outputs together or connect a new radio's powered outputs to an unknown input. Identify the circuit first and follow the selected interface and equipment instructions.
Planning guide, not a fitment guarantee. Exact wiring, impedance, adapters, fasteners and removal procedures must match your vehicle. Photographs show selected vehicle configurations, not universal fitment or a complete removal procedure.
Radio Upgrade
Dashboard fitment follows the original radio configuration. Metra's 99-5820B is a single-DIN kit for specified non-navigation applications, not a general double-DIN solution. Its detailed application list identifies 2009–2013 XL trucks with a CD player, 2009–2012 XLT trucks with a single row of three buttons and no navigation, and 2013–2014 trucks with a CD player but no color screen. Compare the actual dash with the kit instructions before ordering. Other screens and control layouts need a separately verified mounting solution.
Match the installation parts
Select the dash kit and wiring interface for the exact year and audio package. Check whether the antenna connection needs an adapter and whether retained functions need additional hardware. A harness that physically plugs in is not proof that it supports the factory amplifier.
Lay out the radio, kit and harness on a protected workbench. Label each connection by function, make secure insulated joints, and leave enough service length to remove the receiver later without pulling on the wiring.
Check the whole dashboard
Screen size alone says little about fit. Check chassis depth, cable bend space, mounting position and access to nearby controls. With an adjustable or floating display, verify that vents, hazard controls and other important switches remain usable throughout the display's range.
Test reception, each audio source, phone calls, illumination and amplifier turn-on before final assembly. If the radio powers up but the speakers are silent, investigate the amplifier signal and turn-on path rather than immediately replacing the speakers.
The dashboard changed for 2013. Earlier SuperCrew navigation installations have an iDatalink-ready double-DIN/ADS-MRR or ADS-MRR2 route; verify the matching kit. The 99-5820B is not applicable to that navigation setup.
Radio access: eligible CD dashboards
For the 99-5820 CD-radio configurations listed above, release the small switch panel right of the lighter socket to expose one 9/32-inch screw. Lift the rubber mat above the radio/climate panel to uncover two more. Release the vent trim on both sides before unclipping the center panel and disconnecting its plugs. Four further 9/32-inch screws secure the receiver; support it while withdrawing and unplugging it.
Preserve transferred controls
This panel reuses the hazard/airbag-indicator assembly, lighter socket and climate controls. Restore these connections before testing. Follow vehicle battery/restraint precautions; this is not an airbag-service procedure. Do not extend these single-DIN-kit steps to navigation, color-screen or other unmatched dashboards.

Speaker Locations
Measure mounting depth, grille clearance and attachment points at each speaker location. Establish the speaker loads and amplifier signal requirements before replacing either. If keeping the original amplifier, choose compatible speakers; if replacing it, plan the new wiring and crossover arrangement as a system.
Door speakers by cab: 2009–2014
- Regular/Standard Cab: 6×8-inch front doors; some have rear-corner speakers accepting 6×8-inch replacements.
- SuperCab: 6×8-inch front and rear doors.
- SuperCrew: 6×8-inch front and rear doors.
- 5¼-inch alternatives require adapters; verify depth and mounting.
Sony-equipped SuperCab and SuperCrew
- Sony front-pillar tweeters: 4 ohms. SuperCab diameter: 1.646 inches; measure SuperCrew separately.
- Sony center dashboard: 3½-inch speaker.
- Tweeters need adapted mounting/wiring; center brackets may require locating-pin modification.
Sony locations are equipment-specific. Verify your cab and audio package.
Measure more than the cone
Compare mounting-hole positions, opening diameter, basket shape, magnet clearance and available depth with the replacement's drawing. Include any adapter thickness. Check clearance with the window fully lowered and make sure the cone and surround will not touch the grille.
Make the speaker-to-panel connection firm and well sealed. Repair loose clips and deteriorated mounting surfaces before tightening the speaker. Do not use oversized screws where they could contact glass, wiring or a moving mechanism.
Build a balanced front stage
Choose speakers around the power they will actually receive, your listening level and the intended crossover arrangement. With a component set, use the correct crossover and protect the tweeter from low-frequency energy. More speakers do not automatically create a clearer system.
If retaining factory amplification, confirm each speaker's specified impedance and operating range. Changing the load can change output and stress the amplifier. Do not guess impedance from speaker size, connector shape or a badge.
Sound damping can reduce door noise; preserve drainage and service access.
Tools
Use vehicle service information for battery isolation and trim access. Protect airbag circuits and keep new wiring clear of seat movement. Before final assembly, check every audio channel, agreed controls, camera operation where fitted, and normal radio startup and shutdown. Confirm any accepted feature losses with the owner before work begins.
Work safely around the vehicle
Follow the vehicle's battery-disconnection and restraint-system precautions before electrical or trim work. Do not probe airbag wiring. Keep the ignition off during connection work and prevent loose conductors or tools from bridging a power connection to ground.
Before drilling, inspect both sides for wiring, glass, fuel lines and structural or safety components. Stop if you cannot verify the space. Deburr and protect any approved opening so a sharp edge cannot damage a cable later.
Make connections that last
Use connectors and a crimp tool designed for the conductor size. Perform a gentle pull test, insulate exposed conductors and provide strain relief. Twisted wires under ordinary tape are not a durable permanent connection.
Use a meter only in the correct mode. Measure resistance on an isolated, unpowered circuit; never place a meter set to current directly across a power source. If the wiring is unclear, get qualified installation help before applying power.
Regular Cab radio: trim tool, ratchet/extension, 7mm; 2013–2014 adds Phillips, 5.5/10mm. Door work differs with window controls. Restore rear-corner restraint hardware correctly.

Bass and Amplifier
For a Regular Cab, inspect the available space behind the seating before planning an amplifier or subwoofer. For a SuperCab, check rear seating access and clearance around the rear-door wiring routes. For a SuperCrew, measure with the rear seats in every position that will remain in use. These are inspection priorities, not approval for a particular enclosure. Do not transfer mounting measurements from one cab style to another.
Plan the enclosure and power
Measure the proposed enclosure location and access path. Preserve vehicle controls, seat travel and service access, allow amplifier ventilation, and secure equipment so it cannot become a hazard during hard braking. No vehicle-specific enclosure fit is established here.
Match the enclosure to the subwoofer's requirements. Choose power cable, grounding, distribution and fusing for the actual current demand and cable run. Place appropriately rated source protection close to the battery, following the wiring system's requirements. A fuse must protect the cable, not merely match a number printed on an amplifier.
Integrate, then tune
Confirm a suitable signal source before buying a line-output converter or amplifier. Factory outputs may be filtered or change with volume. Match input capability to the measured signal, and keep turn-on behavior controlled so the amplifier shuts down when it should.
Begin with bass boost off. Set gain using the equipment manufacturer's procedure; gain is input sensitivity, not a volume control. Blend the subwoofer with the front speakers using crossover, level and polarity adjustments. Listen for clean transitions rather than simply the loudest bass.
