This is particularly true if you are driving an older model car. Our ears are less sensitive to sounds that are further down the scale. (2) The solid part is also very important when you are creating your box, because if the box can flex around and vibrate, these vibrations will really screw up the overall sound quality and sound pressure level.

Once you have narrowed down your choices to a couple of different speakers, try them out for a while. Once the dash or trim pieces are removed, the radio should be easy to see. Connect the ground wire to the ground connection terminal on the amplifier. When you are using speakers to conduct your sound actually causes a vibration in the air that our ear receives and we hear music.
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
In many cars, door speakers are the easiest to replace. Newer have notched a slot into the edge of the grille. All you have to do is take a screwdriver, pop out the grille, and dismount the factory speaker to get it out.
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.
