Door Panel Removal

Removing the door panel is straightforward. The panel is held by a combination of Phillips screws and plastic snap clips.

  1. Lower the window fully before starting — this prevents the glass from binding against the panel during removal.
  2. Remove the inner door handle trim piece, if present (typically one screw behind it or a pry-tab on the end).
  3. Remove any visible Phillips screws on the panel face — typically one in the door pull handle and one near the bottom edge.
  4. 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.
  5. 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.
  6. 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

Rockford FosgateRFx44-inch upgrade — direct fit, improved output
PioneerTS-A1681F (6.5 inch)Fits with speaker adapter spacer — significant improvement
KickerDSC404 (4 inch)4-inch coaxial — fits stock location
Tip:A 4-inch upgrade (like the Rockford Fosgate RFx4) is the simplest drop-in option — no adapter plate required, and the fit is straightforward. If you want noticeably better bass response without a subwoofer, the 6.5-inch Pioneer with an adapter spacer is a popular choice in the owner community.

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.
