Door Panel Removal
Removing the door panel is straightforward. The panel is held by a combination of Phillips screws and plastic snap clips.
- Lower the window fully before starting — this prevents the glass from binding against the panel during removal.
- Remove the inner door handle trim piece, if present (typically one screw behind it or a pry-tab on the end).
- Remove any visible Phillips screws on the panel face — typically one in the door pull handle and one near the bottom edge.
- Starting at the bottom edge, use a trim panel removal tool (or a wide flat screwdriver with tape to prevent scratching) to pop the plastic snap clips around the perimeter of the panel. Work around all four edges.
- Once all clips are free, lift the panel upward slightly to disengage the top edge from the window sill channel, then pull it away from the door.
- Disconnect the window winder handle (if manual — one spring clip on the spline) before setting the panel aside.
Speaker Adapters / Spacers
The stock speaker cutout is shallow. The OEM 4-inch speakers have very little depth, and most aftermarket speakers are deeper. A 4-inch speaker adapter spacer — available from Etsy sellers and various Acty parts vendors — creates the clearance needed for a deeper speaker cone without the magnet hitting the door glass mechanism.
If you want to fit a 6.5-inch speaker, a custom adapter plate is required. The most common approach uses a 3D-printed or CNC-cut adapter that spans the stock 4-inch mounting hole and provides the larger 6.5-inch bolt pattern.
Aftermarket Speaker Upgrades

| Pioneer | TS-A1681F (6.5 inch) | Fits with speaker adapter spacer — significant improvement |
| Kicker | DSC404 (4 inch) | 4-inch coaxial — fits stock location |
Under-Seat Speaker Placement
The area under the passenger seat has usable space for additional audio components. Many owners mount a small powered subwoofer or a compact amplifier here. The space is wide enough for a shallow 8-inch subwoofer enclosure or a 4-channel amplifier, and the wiring to the head unit and rear speakers is relatively short from this location.
When routing power cables from the battery to an amplifier, use a proper inline fuse (within 18 inches of the battery connection) sized to the amplifier's draw. Route the power cable away from signal cables to minimize noise and interference.
