Start with what is installed
Factory System Overview
Factory options include CD or cassette/CD receivers, Bose audio and later navigation. Replacing the radio removes the original navigation and factory satellite-radio functions. OnStar and steering-wheel controls require compatible retention hardware. A chime-retaining interface also supplies the appropriate switched-power connection for an aftermarket receiver.
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
Confirm Bose versus standard audio, exact model year and body configuration. The supplied overview contains unrelated model-name errors, so those claims are not repeated here.
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
Single- and double-DIN receivers fit with the correct kit, but the plastic rear support needs trimming for clearance. Begin by loosening the center console: remove the storage-compartment screws, the screws under its rubber coin cup and bottom cover, then the screw under the front cup-holder liner.

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
Single- and double-DIN receivers fit with the correct kit, but the plastic rear support needs trimming for clearance. Begin by loosening the center console: remove the storage-compartment screws, the screws under its rubber coin cup and bottom cover, then the screw under the front cup-holder liner. Lift the rear of the console and shift it back only enough to access the radio surround. Remove the trim fasteners and disconnect the panel and radio carefully. Mount the new receiver with the kit, connect the correct chime/OnStar interface and test before restoring the console.
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.
Dash corners, Bose
Browse by size; verify depth, mounting and electrical compatibility.Speaker Upgrades
Check each mounting location separately. Nominal diameter alone does not establish depth, grille clearance, impedance or a suitable signal from the factory amplifier.

Dash corners, Bose
Factory: Tweeters
Replacement planning: Tweeters, custom fit
Access requires A-pillar and upper-dash trim removal. No dedicated bracket or harness is documented.
Front doors, standard
Factory: 6¾-inch woofer and separate tweeter
Replacement planning: 6¾-inch, verify bracket
The woofer receives full-range audio, allowing a suitable coaxial replacement or a component-system approach. Bracket locating tabs need modification.
Electrical note: 4-ohm factory woofer.
Front doors, Bose
Factory: 8-inch woofer
Replacement planning: Verify replacement and adapter fit
The factory amplifier supplies a low-pass signal, so a new full-range speaker will still play only bass unless integration is changed. No Bose front-door adapter harness is documented.
Electrical note: 2-ohm factory woofer; check amplifier loading and level changes.
Rear doors
Factory: Varies with year and factory equipment
Replacement planning: 5¼-inch, 6½-inch, 6¾-inch
The source supports these nominal replacement sizes depending on the exact truck. Remove locating tabs as needed so the selected speaker or adapter sits flat.
Access and mounting
Remove the door panels carefully around their retaining clips. Front mounts may need limited material removal and locating-tab trimming, while rear brackets can require removing additional square tabs. Confirm each fit before altering parts. Bose amp bypass planning must account for the amplifier in the right rear cargo area. Before reinstalling door panels, verify speaker polarity, window clearance and door release and lock operation.
Test before closing
Confirm polarity and each channel at a moderate level. Check window travel, latch operation and wiring clearance. Replace damaged clips and secure every panel without pinching its harness.
Tools
Phillips and small flat-blade screwdrivers, panel tool, 7mm and 10mm sockets, ratchet and extension, Torx T15 driver and pliers; suitable trimming tool when required.
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
The researched cargo space allows an approximately 45-inch-wide, 14-inch-high, 34-inch-deep enclosure envelope. Recheck with the actual seats and cargo needs before building. A compact powered enclosure can preserve more usable luggage room. Secure the enclosure and plan suitable fused power, signal integration and ventilation; a Bose front-door bass signal is not automatically the best full-system signal source.

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.
