Start with what is installed
Factory System Overview
Early trucks offer 4.2-, seven- and eight-inch factory displays. The standard system has six speakers; the Bose system adds a center dash speaker for seven. Do not assume that a receiver installation suitable for a 2015 truck also applies to a 2022 model. The supplied reference specifically advises against replacing the radio in 2019–2022 trucks without Bose.
Planning guide, not a fitment guarantee. Match all wiring, mounting dimensions, impedance, adapters and removal procedures to the exact vehicle. Photographs show selected configurations rather than every available system.
Radio Upgrade
For a 2015–2018 truck, conventional aftermarket radio installation can require cutting the plastic rails in the dash. That modification is irreversible and prevents reinstalling the original radio. Check the full kit instructions and exact vehicle compatibility before committing. Direct-replacement packages may avoid the same modification, but that is a product-specific question rather than a general promise.
The later-model restriction matters
For 2019–2022 non-Bose trucks, retain the factory radio under this guide's recommendation. Speaker upgrades remain an option. For Bose trucks, verify the particular radio and interface combination before assuming replacement is supported.
Keep warning chimes working
Use an appropriate integration interface that preserves the factory warning chimes. Confirm separately how equipped OnStar, steering-wheel controls and the backup camera will be handled. The original USB, navigation or satellite-radio functions may not transfer directly to a new receiver.
Test before replacing the trim
Identify each retained feature before dismantling the center stack, then test that list after wiring the receiver. This avoids discovering a missing camera or control function after the dash has been reassembled.
Factory Speaker Locations & Sizes
Use these collection links to compare size categories, then verify the specific speaker, bracket, depth and wiring for your installation. A matching size label alone does not establish fit.
Dash corners • Tweeter options

Bose center dash • 3-1/2-inch speakers

Front doors • 6x9-inch speakers

Rear cab speakers • 6-1/2-inch alternatives
Shop 6-1/2-inch alternativesFactory 6-3/4-inch speakers can be replaced by suitable 6-1/2-inch drivers. Access differs between cab styles.
Base and Bose wiring differ
In the base system, the dash-corner speakers are wired in parallel with the front-door speakers. Bose uses amplification that changes the signal path. Check how the proposed components will work together rather than replacing each driver as an isolated part.
Front doors
Door-panel removal gives access to the 6x9 speakers. A smaller round speaker needs the correct mounting arrangement. Standard four-ohm replacements may reduce output compared with the original low-impedance Bose speakers, so resolve that choice before buying.
Crew Cab versus Extended Cab
Rear speakers are 6-3/4-inch factory units, but the access procedure is not the same in both cabs. Extended Cab work involves a seat-belt anchor. Restore safety-critical fasteners to the vehicle manufacturer's procedure and torque specification; use a qualified installer if that information or experience is missing.
Tools & Preparation
Common speaker-access tools include a panel tool, small flat-blade screwdriver and 7mm and 10mm sockets with a ratchet and extension. Extended Cab rear access also calls for Torx T30. Have the cab-specific instructions ready before removing trim or seat-belt hardware.
Use the vehicle-specific removal instructions and appropriate electrical safety procedure. Keep fasteners organized, protect exposed trim and check wiring or moving parts behind any new mounting hole.
Adding Bass
There is not useful space for a conventional subwoofer box behind the rear seats in the arrangements covered by the reference. A compact powered subwoofer may suit the available space better. Measure with the seats operating normally, check all clearances and preserve access to storage and safety equipment. This guide does not identify a factory subwoofer location to replace.
Installation Checklist
- Confirm year, cab style and base or Bose equipment.
- Retain the radio in 2019–2022 non-Bose trucks.
- Understand any irreversible dash cutting before proceeding.
- Verify warning-chime and camera integration.
- Match the speaker brackets and amplifier load.
- Use the proper seat-belt fastener procedure during Extended Cab work.
