📢 Important Updates & Notes
Speaker bracket update: Kicker has changed the speaker mounting brackets. The brackets supplied with your bundle may look different from those shown in the video. Use the video as a reference for vehicle disassembly and reassembly, and follow the written bracket instructions below. If your supplied parts do not match these instructions, stop and contact us before modifying a bracket or forcing it into place.
Rear speaker sizes: This guide covers the 6.5-inch and 6.75-inch rear-door and rear-hatch options.
Protect your speakers: Handle speakers by their frames. Do not press on the cones, surrounds, terminals, or the small board where the speaker wires connect. Start fasteners by hand and tighten only until secure; do not overtighten.
Before unplugging or reconnecting speakers, turn the vehicle and audio system off. Support each trim panel while disconnecting it so it does not hang from its wiring or handle cables. Photograph cable positions and connector routing before removal, and keep the fasteners from each location together.

- 10mm socket and ratchet wrench.
- T20 Torx bit and a compatible driver for the factory dash-speaker bracket screws.
📝 Step-by-Step Instructions
Step 1: Check Your Bundle & Prepare
🎥 Watch the bundle and included-parts overview (1:20)
- Inspect the packaging and all components for shipping damage before starting.
- Lay out the speakers, brackets, harnesses, crossovers, and supplied screws. Keep parts labeled for the dash separate from the door and hatch parts.
- Confirm that your bundle includes:
- Two 6×9-inch front-door speakers and two 2.75-inch dash speakers, with the supplied crossover and adapter wiring.
- One pair of 6.5-inch or 6.75-inch rear-door speakers with speaker-wire adapters.
- One pair of 6.5-inch or 6.75-inch rear-hatch speakers with speaker-wire adapters.
- Set aside a safe place for removed trim and fasteners. If a component is missing or damaged, contact us before proceeding.
Step 2: Remove the Factory Dash Speakers
🎥 Watch dash-speaker removal (5:02)
- Slide a panel removal tool under the edge of one dash-speaker grille. Gently work around the edge to release the clips, then lift off the grille.
- Remove the two 10mm-head bolts securing the speaker assembly to the dash. Save them for reinstallation.
- Lift the assembly enough to reach its connector. Press the connector’s release tab and pull on the connector housing, not the wires.
- Remove the two T20 Torx screws securing the factory speaker to its mounting bracket. Keep the screws and factory bracket; both will be reused. Seat the bit fully and turn carefully, as these screws can be very tight.
- Release the factory connector from the bracket as needed to separate the speaker from the reusable bracket.
Step 3: Install the Kicker Dash Speakers
🎥 Watch dash-speaker assembly and installation (6:54)
- Gather one 2.75-inch Kicker dash speaker, its supplied mounting-adapter pieces, the factory bracket and screws, and the crossover/connector assembly from the bag labeled DASH.
- Place the larger Kicker adapter piece into the factory mounting bracket. Rotate it until the mounting holes align; do not force it.
- Set the Kicker speaker into the adapter, keeping its terminals and attached wiring clear of the bracket.
- Position the smaller adapter piece over the speaker and align its holes with the lower adapter. Keep the adapter clear of the cone and surround.
- Reinstall the two factory T20 screws to secure the assembly. Tighten only until secure.
- Connect the supplied dash crossover to the speaker leads. Match the 1/4-inch and 1/8-inch spade connectors to their corresponding terminals. A spade connector is the flat push-on electrical connector; do not force a mismatched size. Ensure the insulating covers protect the connections.
- Connect the adapter harness to the factory dash-speaker plug. Tuck the crossover and wiring into the dash without pinching them beneath the bracket.
- Reinstall the assembly using the two factory 10mm-head bolts, then gently press the grille back into place.
Repeat Steps 2–3 for the other dash speaker.
Step 4: Remove the Front Door Panel
🎥 Watch front-door panel removal (10:02)
- Pull off the small interior trim piece beside the side mirror.
- Carefully release the screw covers behind the interior door handle, near the top of the grab handle, and below the grab handle.
- Remove the three Phillips screws behind those covers. Note where each screw belongs.
- Use your hands and a panel tool to release the retaining clips around the panel’s edge. If a section will not release, check for an overlooked fastener rather than pulling harder.
- Lift the panel upward to unhook its top edge from the window ledge. Support the panel close to the door.
- Photograph the door-handle cables. Release each cable housing from its retainer, then rotate the cable end to lift its ball-shaped end out of the handle mechanism.
- Press the release tabs and disconnect the window-switch and courtesy-light connectors. Set the panel aside.
- If a retaining clip stayed in the metal door, remove it with a panel tool and reinstall it in its matching position on the trim panel.
Step 5: Remove the Factory Front Door Speaker
🎥 Watch factory front-door speaker removal (13:40)
- Press the release tab and unplug the factory speaker connector.
- Support the speaker while removing its four 10mm-head mounting bolts.
- Remove the speaker and save all four bolts for the new mounting bracket.
Step 6: Install the Kicker Front Door Speaker
🎥 Watch front-door bracket, wiring, and speaker installation (14:19)
- Align the supplied 6×9-inch mounting bracket with the door’s mounting holes. Start all four factory bolts by hand before tightening them evenly.
- Connect the supplied front-speaker crossover/adapter wiring to the speaker using the matching 1/4-inch and 1/8-inch spade connectors. Use the harness intended for this location, not the dash harness.
- Connect the adapter harness to the factory speaker plug.
- Route the speaker wire through the channel in the mounting bracket so the wire is not trapped between the speaker frame and bracket. Keep loose wiring clear of moving window components.
- Place the speaker in the bracket, align the mounting holes, and secure it with the supplied Phillips screws. Keep the screwdriver clear of the cone and surround.
Important: Before fully reinstalling each door panel, check for trapped wires and loose connections. You can briefly test the speaker at low volume once all electrical connections are secure. Turn the audio system and vehicle off again before adjusting any wiring.
Step 7: Reinstall the Front Door Panel
🎥 Watch front-door panel reassembly (17:26)
- Confirm that all retaining clips are fitted to the panel.
- Reconnect the window-switch and courtesy-light connectors.
- Reattach the door-handle cables: seat each ball-shaped end in its original location, rotate the cable housing into position, and secure its retainer. The original guide identifies the white retainer as the upper cable and the green retainer as the lower cable; compare with your removal photo.
- Check that the cable housings are fully seated and that the handle and lock mechanisms move freely before closing the door.
- Hook the top edge of the panel over the window ledge, then lower it into position. Align the retaining clips before pressing around the panel’s edge.
- Reinstall the three screws in their original positions. The silver screw goes behind the door handle; the black screws go in the other two locations.
- Close the screw covers and press the side-mirror trim piece back into place.
Repeat Steps 4–7 for the other front door.
Step 8: Remove the Rear Door Panel
🎥 Watch rear-door panel removal (20:33)
- Release the three screw covers behind the interior door handle, near the top of the grab handle, and below the grab handle.
- Remove the three Phillips screws and keep track of their positions.

- Support the panel while photographing and disconnecting the handle cables. Release each housing retainer, then rotate and lift out the cable’s ball-shaped end.
- Press the release tab and unplug the window-switch connector. Set the panel aside.
- Transfer any clips left in the metal door back into their matching locations on the panel.
Step 9: Remove the Factory Rear Door Speaker
🎥 Watch the end of panel removal and factory rear-speaker removal (21:50)
- Press the release tab and disconnect the speaker plug.
- Support the speaker and remove the three 10mm-head mounting bolts.
- Lift out the speaker and save the bolts.
Step 10: Install the Kicker Rear Door Speaker
🎥 Watch rear-door bracket, wiring, and speaker installation (23:03)
- Align the supplied rear-door speaker bracket with the three factory mounting holes. Rotate it until the holes line up, then start all three factory bolts by hand and tighten evenly.
- Connect the supplied rear-door speaker-wire adapter to the speaker, matching the 1/4-inch and 1/8-inch spade connectors to their corresponding terminals. Use the wiring supplied for the rear speakers; do not substitute a dash or front-door crossover.
- Plug the adapter into the factory speaker connector.
- Route the wire through the bracket’s wire channel and position the 6.5-inch or 6.75-inch speaker in the bracket. Check that no wiring is pinched or hanging near moving window components.
- Secure the speaker with the supplied Phillips screws, keeping the tool clear of the cone and surround.
Step 11: Reinstall the Rear Door Panel
🎥 Watch the final speaker fit check and rear-door panel reassembly (25:56)
- Confirm that all retaining clips are installed in the trim panel and reconnect the window-switch connector.
- Reattach the handle cables in their original positions, seating the ball ends and securing the housing retainers. Compare with your removal photo; the original guide places the white retainer above the green retainer.
- Check handle and lock movement before closing the door.
- Hook the top edge of the panel over the window ledge and lower it into position. If access is difficult, lowering the window can help; ensure the switch is connected and all wiring is safely clear before operating it.
- Align the retaining clips and press the panel into place around its edge.
- Reinstall the silver screw behind the handle and the black screws in their original grab-handle positions. Close the covers.
Repeat Steps 8–11 for the other rear door.
Step 12: Remove the Rear Hatch Trim Panel
🎥 Watch rear-hatch handle, lights, and trim-panel removal (28:35)
- Open the hatch fully and make sure it is securely supported before working underneath it.
- Use a panel tool to release the pull-handle trim cover. Remove the 10mm-head handle fastener and handle as needed to free the trim panel; keep the parts together for reinstallation.
- Carefully release the hatch-light assemblies with a panel tool. The original guide specifies prying from the driver-side edge. Support each assembly, release its wiring connector, and set it aside.
- Support the large trim panel while releasing the retaining clips around its edge. Lift the panel off the window ledge once the clips and any remaining attachments are free.
- Remove any clips left in the hatch and reinstall them in the trim panel.
Step 13: Remove the Factory Rear Hatch Speakers

🎥 Watch rear-hatch bracket, wiring, and speaker installation (32:28)
- Attach the supplied speaker mounting bracket to the factory speaker mounting points in the hatch using the three saved bolts. Start each bolt by hand before tightening.
- Connect the included hatch-speaker adapter to the Kicker speaker, matching the 1/4-inch and 1/8-inch spade connectors to the corresponding terminals.
- Connect the adapter harness to the factory hatch-speaker plug.
- Route the wire through a channel in the bracket, then place the speaker in the bracket without pinching the wiring.
- Align the mounting holes and secure the speaker with the supplied Phillips screws. Keep the screwdriver away from the cone and surround.
- Repeat for the other hatch speaker. Check that both harnesses are connected before reinstalling the trim.
Step 15: Reinstall the Rear Hatch Trim Panel
🎥 Watch the final wire-clearance check and rear-hatch reassembly (34:51)
- Position the hatch-light wiring so you can reach it through the light openings; do not trap it behind the trim.
- Hook the trim panel over the window ledge and align its retaining clips with the hatch.
- Support the panel while pressing the clips into place around the edge and at the center mounting locations.
- Reinstall the pull handle with its saved 10mm-head fastener, then replace its trim cover.
- Reconnect the hatch-light wiring and carefully press both light assemblies into place.
Step 16: Test Your Installation
🎥 Watch the completed-install listening demonstration (37:02)
- Confirm that tools and loose fasteners have been removed from the vehicle and that all panels are secured.
- Turn on the audio system at low volume and play a familiar track.
- Use balance and fader controls, where available, to check sound from each area. Listen near each of the eight speakers rather than assuming that sound elsewhere confirms every speaker is working.
- Listen for buzzing, rattling, distortion, or missing audio. If you need to inspect a connection, turn the vehicle and audio system off first.
- Check the windows, door locks, interior handles, courtesy lights, and hatch lights after reassembly. Confirm that handle cables operate correctly before closing each door.
First listening sessions: Begin at moderate volume and avoid pushing the system into audible distortion. Follow Kicker’s owner’s manual for speaker-use guidance.
Congratulations on installing your Kicker 8 Speaker Plug & Play Bundle!
🛠️ Common Troubleshooting Solutions
No Sound from One Speaker
Check balance and fader settings first. Turn the vehicle and audio system off before checking that the factory plug, adapter connection, and speaker terminals are fully seated. Verify that you used the harness supplied for that speaker location. Do not force connectors or cut factory wiring to resolve a mismatch.
Buzzing or Rattling
With the audio system off, inspect for loose mounting screws, unsecured trim clips, and wiring resting against a panel or speaker. Confirm that no wire is trapped beneath the speaker frame. Tighten fasteners only until secure; overtightening is not a fix for a misaligned bracket.
A Bracket or Panel Will Not Fit
Check the bracket’s orientation, speaker location, and mounting-hole alignment. For trim panels, confirm that all fasteners have been removed during disassembly and that clips are aligned during reassembly. Remember that updated Kicker brackets may differ from the video. Stop and contact us if the supplied parts still do not align.
A Handle, Lock, Window Switch, or Light Does Not Work
Compare the cable positions with your removal photo and check the relevant electrical connectors with the vehicle off. Confirm that handle-cable housings are secured in their retainers. Do not close a door until its handle and lock mechanisms operate correctly.
