[. . . ] In most cases it will be "press-fit" or screwed to mounting tabs molded into the surrounding area. If you experience any resistance, consult your dealer or your car's owner's manual to determine if there is any special way the manufacturer has secured the grille. Remove all screws, mounting clips or lock washers holding the factory speaker in place and save them for reuse. Lift the speaker out of the hole a short distance. [. . . ] Draw the inside circle and mark at least two opposing screw locations. Cut the circle with the appropriate tool. Drill pilot holes for the screw locations. File the edges of any bare metal surfaces until smooth, then coat with primer to prevent rust. When primer is dry, slip mounting clips over the screw holes. In the meantime, run wires from your amplifier or radio to the speaker locations. Use grommets when passing through doors. Connect the wires to your new Polk Audio speakers. Hook the positive [+] wire to the wider of the two GXR terminals and the negative [­] to the narrower GXR terminal. Carefully align the speaker and beauty ring holes over the new screw holes and mounting clips. Tighten the screws firmly to secure the speaker to the mounting surface.

Remove only the flange(s) that are necessary to make the speaker fit the chosen location. Secure the speaker with at least two opposing flanges. In some vehicles, you may have to bend or angle (but not break) one of the two flanges to get the proper fit when installing the speakers in your dashboard. Do not use a sander or grinder, as that could cause fine metal shavings to fall into the voice coil and driver suspension units. If you have a subwoofer in your system, you may want to decrease the amount of bass frequencies going to your mid-range speakers (which is what your "full range" speakers would be if you had a subwoofer in your system). Doing this will result in better mid-range detail and increased power handling. There are two ways to roll off the bass before it gets to your mid-range speakers. One way is to use a "bass blocker, " a capacitor placed in series with the speaker input. Bass blockers are installed in series, one end connected with the positive lead from your amplifier and the other end connected to the positive lead of each of your speakers (FIG.
