Remove the door lock button. Simply screw it out by turning it counterclockwise until it comes loose, and pull it off the threaded stud. Remove the window crank. You will need a tool to release the snap ring, if it is installed this way. Check an auto parts supply for the proper tool for your model. Slide the tool between the base of the crank and the door panel, opening a gap to see the retainer with a small prying tool like a flat blade screwdriver.
Snap the snap ring off the window crank's shaft, and pull the crank off. For crank handles with a threaded fastener visible in the center of the hub, simply unscrew the fastener and pry the handle off. Remove any that are obviously holding the panel in place. Use a flat pry bar or wide, flat screwdriver to pry the panel clips around the edge or seam of the door panel. These clips are spring loaded, and should snap free with minimum effort. Work all the way around the sides and bottom of the panel, being sure to disengage the clips completely.
Lift the panel upwards while pulling it out from the window crankshaft, and it should snap free of the trim at the edge of the window. Do not pull far enough away from the door itself to damage wiring for electric locks and windows, if the car is so equipped.

Match your new speakers to the old ones, both in diameter, shape, and depth. Very high powered speakers may not have space for the ceramic magnets attached to the back of the speaker frame, so it is probably best to measure this clearance before buying your new speakers.

Clamp your new speakers into the door. If the original equipment clamps don't fit your new speakers, you may want to pop rivet or use self drilling machine screws to attach them.
Reattach the speaker wires, noting the positive and negative positions. If you don't have a mark or know the polarity of the wires, you may have to test the speakers prior to reinstalling the door. Powering the speakers with reverse polarity should not damage them unless you have a highly amplified system, but it is always better to connect them properly the first time.

Reassemble the door panel, and reinstall the window crank and lock knob in reverse order. New Speakers in Different Locations Select the location of your new speakers. This option allows you to put much larger speakers in your car if you choose the proper location. Here are some possible choices. In the rear dashboard. Install speakers here, behind the backseat headrest, by laying out holes with the cutting templates provided with your new speakers, or by tracing the outline of your new speaker grill, and cutting the hole half an inch or so smaller. Mounted to the top of the cabin. You may buy speakers with enclosures suitable for mounting in the ceiling of your car.
You will want to be sure they allow headroom for all passengers, and do not interfere with the view in the rear-view mirror. Also consider how you will route the speaker wires, as fabric headliners are difficult to attach the wires to, and headliners cannot be reattached like the door panels can be. This is the easiest way, but will not offer the optimum acoustics, since the seats will absorb much of the sound they produce.
The speakers will be subject to considerable vibration if mounted on the floor of the vehicle, as well.
Cut holes for rear dashboard mounted speakers, or use hardware supplied for ceiling or floor mounted speakers, and secure the assembly. Route speaker wires at the edge of upholstery or flooring to the firewall behind the dashboard, then up to the stereo. Keep them tidy, either clamping them or tucking them under the trim or edge of the flooring to keep them in place. Most factory-installed speaker wiring uses copper-colored wire for positive and silver-colored for negative.
A few others use the same color wiring but put a raised strip on the negative side of the wire. Most car amps have 4-ohm output impedance. Make sure your speakers are the same impedance. The impedance is usually listed on the back of the speaker and on the output terminals of your car stereo. If you replaced the factory-installed speakers, the installation manual should tell you the impedance.
Turn the balance control on your car stereo from one side to the other to check the sound for balance after your installation is complete.

If your left and right balance is reversed, switch the RCA-type audio output plugs, either on the back of the amp or on the back of your car stereo, whichever is easier to access.

Tip If your speaker wire is too short to reach the amp or you choose to mount the amp in an out-of-the-way spot like the trunk, take the speakers out of their door mounts, remove the old wire from the terminals on the far side and attach them to a string with duct tape. Pull the string to the trunk-mounted amp.
