Installing your Speakers


Every car is different, so things may vary. However as the method is the same, here are a few general tips to keep in mind as you plan your speaker installation.

Replacing dash speakers
Most dash speakers are easily replaced by removing the grilles, which are held down by screws or friction fittings. If the grille is held in place by friction fittings, carefully pry it up. In some cases the grille is secured from the bottom by screws, or by plastic studs which can break with excessive force. In such cases, the entire dash panel may need to be removed.

Remove the old speakers, making sure to note the polarity of each terminal. The speaker's positive terminal is the bigger one and usually is marked with a + sign or a colored dot. Use your wiring harness to attach the new speaker, or solder or crimp the connections.

Replacing door speakers

Step 1.
Remove the grille and factory speaker. Some manufacturers also use a sealant or foam when they first mount the speaker so you might need to cut through that material with a utility knife.

Step 2.
Unplug the factory wiring harness, and attach the Crutchfield wiring harness to your new speaker's terminals. With the wiring harness connected to your new speaker, just plug the other end of the harness into the factory wiring harness.

Step 3.
Check one last time to be sure that all of your wiring is secure, and then screw the new speaker into place in the factory mounting and re-attach the factory grille.
