Preparation

Park vehicle on level surface and engage parking brake
Ensure ignition is off and key/phone is away from vehicle
Open rear cargo doors for access
Disconnect 12V auxiliary battery negative terminal located under hood
Wait 5 minutes for vehicle systems to fully power down
Identify subwoofer location (typically under driver seat or in rear cargo panel depending on EDV configuration)
Document existing wiring connections with photos before disconnection

Procedure

1
Access subwoofer location
For driver seat installation: Remove driver seat by disconnecting electrical connectors underneath and removing four T25 Torx bolts securing seat rails to floor. Carefully tilt seat rearward and remove from vehicle. For rear cargo installation: Remove rear interior panel using panel removal tools to release retaining clips along perimeter.
2
Remove protective cover
Locate subwoofer protective cover or enclosure. Remove T20 Torx screws securing cover (typically 4-6 screws depending on location). Carefully set cover aside with screws organized for reinstallation.
3
Disconnect subwoofer electrical connector
Locate the main audio harness connector at the subwoofer. Press release tab and carefully pull connector straight out from subwoofer terminal. Verify no resistance; do not force connector.
4
Remove subwoofer mounting hardware
Remove mounting bolts or brackets securing subwoofer to vehicle structure. Typically four 10mm bolts or T25 Torx screws. Support subwoofer weight while removing final fastener.
5
Extract subwoofer assembly
Carefully lift subwoofer from mounting location, ensuring no wires are caught or pinched. Tilt as necessary to clear surrounding structures. Inspect mounting area for any damage or debris.
6
Inspect mounting area and harness
Check mounting surface for cracks, corrosion, or damage. Inspect electrical connector pins for corrosion or bent terminals. Clean mounting surface with isopropyl alcohol if necessary. Verify harness routing is clear of sharp edges.
7
Test new subwoofer (optional)
If available, use multimeter to verify impedance of replacement subwoofer matches original specification (typically 2-4 ohms). Check voice coil for continuity and verify no short to ground.
8
Install replacement subwoofer
Position new subwoofer into mounting location, aligning mounting holes with vehicle structure. Ensure gasket or seal (if equipped) is properly positioned. Thread all mounting bolts finger-tight before final tightening.
9
Secure mounting hardware
Tighten all mounting bolts in cross-pattern sequence to ensure even pressure distribution. Use 10mm socket or T25 Torx driver as appropriate. Verify subwoofer is secure with no movement or rattles.
10
Reconnect electrical connector
Align electrical connector and press firmly until release tab clicks into locked position. Gently tug connector to verify secure connection. Ensure harness routing matches original path without tension or kinks.
11
Reinstall protective cover
Position subwoofer cover or enclosure back into place. Install all T20 Torx screws and tighten securely. Verify cover sits flush with no gaps.
12
Restore access panels
If driver seat was removed: Reinstall seat by reversing removal procedure, connecting all electrical connectors before securing T25 Torx bolts. If rear panel was removed: Align panel and press firmly to engage all retaining clips, replacing any damaged clips as needed.

Reassembly

Reconnect 12V auxiliary battery negative terminal
Power on vehicle and allow infotainment system to fully boot
Replace any damaged trim clips with new ones from Rivian parts kit
Ensure all panels are flush and secure with no rattles

Verification

Turn on vehicle and access audio system settings through center display
Play audio with significant bass content to test subwoofer operation
Verify no rattles, buzzing, or distortion at various volume levels
Test fade/balance settings to confirm subwoofer is properly integrated with system
Check for any fault codes in vehicle diagnostics related to audio system
Verify all trim panels and seat (if removed) are securely reinstalled
Test seat occupancy sensors and seatbelt indicators if driver seat was removed
