Start with what is installed
Factory System Overview
The standard system has six speakers and an AM/FM/XM/CD/MP3 receiver. The nine-speaker Pioneer option adds a center-dash speaker, two rear-deck woofers and an amplifier behind the passenger-side trunk trim. Navigation was also offered. This guide covers the first-generation sedan and the carryover 2016 Cruze Limited, not the redesigned 2016 Cruze.
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
Single-DIN and double-DIN receivers are installation options with the correct dash kit. The factory radio supplies the warning chime, so an appropriate interface must retain audible safety warnings and provide switched 12-volt power. Do not plan a radio swap around a bare wiring connection that omits those functions.

Access and integration
Removing the receiver involves the receiver trim, shifter trim, lower pocket and climate-control panel before the faceplate, display and radio chassis can come out. Protect the console while resting the control panel on it. Keep the 7mm screws grouped by their original locations, and restore the shifter to Park after access is complete.
Check the complete system
Depending on the original receiver, replacement can remove the information-center display, factory satellite radio and navigation. The original backup camera, where equipped with its dedicated display, is separate from that loss. Check steering-wheel-control integration against the chosen receiver and adapter before ordering.
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.
Pioneer center dash • 3.5-inch
Browse 3.5-inch speakersThe speaker is bottom-mounted to the grille. Direct-fitting choices are limited; measure depth and mounting points. No plug-in wiring adapter is documented.
Front pillars • 1.600-inch tweeters
Browse car tweetersThe tweeters attach to the backs of the pillar trim. Replacement tweeters need secure custom mounting and appropriate wire connections.
Front doors • 6.75-inch factory
Browse 6.5-inch replacementsThe guide identifies 6.75- and 6.5-inch replacement options with mounting brackets. Confirm each speaker and bracket combination.
Rear doors • 6.75-inch factory
Browse 6.5-inch replacementsRear doors use the same nominal factory size and bracket-dependent replacement categories as the front.
Pioneer rear deck • 6×9-inch woofers
Browse 6×9-inch speakersThis size collection is not a direct substitute list for the factory bass drivers. Check the amplifier signal, crossover and impedance; ordinary coaxials are not equivalent subwoofers.
Access and mounting
Front-door access starts with the sail panel and screw covers. Two T20 screws and the panel clips must be released before disconnecting the door-release cable and wiring. A 7mm screw holds the speaker at its top; lift the speaker after releasing it. Rear-door work is similar. Use the specified mounting brackets rather than relying on the factory basket to accept every nominally similar driver.
Details to plan before disassembly
The Pioneer rear-deck pair requires substantially more trim and seat-area access than the door speakers. New mounting holes may be necessary. Inspect behind the drilling point, wear eye protection and preserve the third brake light wiring. After reassembly, verify the brake light and secure all disturbed seats and seat belts to the vehicle manufacturer’s requirements.


Tools & Preparation
Panel tool, T20 driver, 7mm socket with ratchet and extension, small flat-blade and Phillips screwdrivers. Rear-deck installation may also require drilling tools for the selected brackets.
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
The source measures trunk space at approximately 40 inches wide, 17 inches high and 31/36 inches deep. Treat those as planning measurements, not a guaranteed enclosure fit: check the opening, mounting location and access to the spare. A compact powered subwoofer can preserve more usable cargo space than a large enclosure.
Installation Checklist
- Confirm the exact year, body style and installed audio system.
- Check physical fit, impedance and signal filtering at every speaker location.
- Match the radio interface to the features that need to remain functional.
- Test each speaker and retained control before refitting trim.
- Check door locks, handles and window movement after door work.
- Restore any disturbed seats, seat belts and safety equipment to manufacturer requirements.
